Opis:

The objective of the present work is to find out the viable substitute fuel for diesel and control of pollutants from compression ignition engines. Therefore, in this present investigation an attempt has been made to study the effect of 20% proportion of five different biodiesel diesel blend in diesel engine. The 20% proportion of biodiesel such as Jatropha, Pongamia, Mahua, Annona and Nerium and 80% of diesel and it is denoted as J20, P20, M20, A20 and N20 are used in the present investigation. The experimental results showed that the brake thermal efficiency of the different biodiesel blend is slightly lower when compared to neat diesel fuel. However, N20 blend, have shown improvement in performance and reduction in exhaust emissions than that of other biodiesel diesel blends. From, the experimental work, it is found that biodiesel can be used up to 20% and 80% of diesel engine without any major modification. The conducted experiments were conducted on a four cylinder four stroke DI and turbo charged diesel engine using biodiesel blends of waste oil, rapeseed oil, and corn oil with normal diesel. The peak cylinder pressure of the engine running with bio diesel was slightly higher than that of diesel. The experiments were conducted on a four cylinder four stroke diesel engine using bio diesel made from corn oil.

Opis:

In the operating marine diesel engines the indication diagnostics tests are usually performed through a 0.5-1.0 me ter long indication channel which delays and disfigures the pressure signal being measured. the delay depends on the engine 's speed and load. the pressure sensor itself together with an amplifler is an additional source of delay and disfigurements, so the registered pressure curve is displaced even if theTDC piston's position hadbeen estimated with the highest accuracy. when the over exploited engine is being tested the angle of delay can achieve several degrees and differ for each cylinder. in that case cylinders' load is unequal and torsional vibrations occur in the engine operation. in case when some simplifying assumptions have been adopted the part of diagnostic information is lost what could lead to a false diagnosis. in the paper the attention is focused on the mistakes which could be made in the marine diesel engine diagnostics when different TDC assessment methods are used. TDC corrections with compression pressure analysis are possible only in case when crankshaft angle position is precise. in case of measurement with constant frequency such corrections are possible only when the engine is good balanced.

Opis:

The paper presents the results of on-road exhaust emission tests of passenger car fitted with diesel engine, and a DPF (diesel particulate filter). Under such conditions the author could determine the actual vehicle emissions. The tests were performed on a road portion of a fifty kilometres or so - these tests provide information on the on-road emissions and are a basis for their ecological evaluation. For the measurement of the exhaust emissions the authors used a portable exhaust emissions analyzer SEMTECH DS by Sensors Inc. The analyzer measured the concentration of the exhaust components at the same time measuring the exhaust mass flow. The measurements of the particulate matter (mass) were done with the use of particle analyzer by AVL. The obtained data were used to calculate the relations that characterize the influence of the dynamic engine parameters on the exhaust emissions. These properties were taken into account indirectly using the whole range of speeds and accelerations of the vehicle (engine speeds and loads of the engine) for the preparation of the matrices of the emissions rate. The used data were averaged within individual speed and acceleration ranges thus obtaining the characteristics of the share of operation in individual ranges and the characteristics of the emission matrices of the individual emission components. The above results served for defining of the emission level indicator of the vehicles that can be used for classification of vehicle fleet in terms of their emission level.

Opis:

The process of fuel combustion in a diesel engine is determined by factors existing during liquid fuel injection and atomisation. The physicochemical properties of the fuel to a large extent decide upon the quality of this phase of cylinder fuelling. So it is important to ensure appropriate properties of a fuel affecting its atomisation and, as a result, combustion. The paper deals with the topic of diesel oil improvers and the analysis of their influence on atomisation and combustion indices. In the studies base diesel oil and a diesel fuel improved by a package of additives, were used. The process of conventional and improved fuel injection was analysed by using optical examinations. The amount of released heat was evaluated during the studies carried out on combustion. Significant aspects of the applied improvers in relation to fuel injection and its combustion have been indicated.

Opis:

The increasing industrialization and development in the field of transport sector of the world have led to a steep rise for the demand of petroleum products. Petroleum fuels are obtained from limited reserves of foreign countries. Presently our country is facing the problem of foreign exchange due to the import of crude oil. Hence, it is necessary to look for alternative fuel, which can be produced from available raw material within the country. In the present investigation, the bio-diesel produced from the jatropha seeds have been considered as a potential alternative for running the compression ignition engines. The different blends of bio-diesel and conventional diesel have been tested on the engine. The experimental data obtained for various concentrations of bio-diesel blends have been compared with base line data of conventional diesel. Significant improvement in engine performance has been observed due to the use of bio-diesel. Acceptable thermal efficiencies of the engine have been obtained with different blends of bio-diesel and diesel. It has been observed that 20% of jatropha oil can be substituted for diesel without any engine modification and preheating of the blends.

Opis:

The article presents bench test results of a four-stroke, four-cylinder, naturally aspirated, DI diesel engine operating with neat JP-8 fuel (J) and its blends with Diesel fuel (D) in following proportions by volume: 90/10 (J+10D), 70/30 (J+D30), 50/ 50 (J+D50), 30/70 (J+D70), and 100% diesel fuel (DF). The purpose of the research was to analyse and compare changes occurred in the autoignition delay, combustion events, engine performance efficiency, emissions, and smoke of the exhaust when running on JP-8 fuel, jet-diesel fuel blends, and diesel fuel at a full (100%) engine load and speed of 1400 min–1 at which maximum torque occurs and rated speed of 2200 min–1. It was found that the start of injection (SOI) and the start of combustion (SOC) occurred earlier in an engine cycle and the autoignition delay decreased by 9.0% and 12.7% due to replacement of aviation JP-8 fuel with diesel fuel at a full load and the latter speeds. Maximum in-cylinder pressure was 6.8% and 4.0% higher when operating with diesel fuel, whereas brake thermal efficiency was 3.3% and 7.7% higher, and brake specific fuel consumption 2.8% and 7.0% lower when using fuel blend J+D50 compared with the respective values measured with neat JP-8 fuel. Emissions of nitric oxide (NO) and nitrogen oxides (NOx) were 13.3% and 13.1% higher from a straight diesel running at speed of 1400 min–1, and 19.0% and 19.5% higher at a higher speed of 2200 min–1. The carbon monoxide (CO) emissions and total unburned hydrocarbons (HC) decreased 2.1 times and by 12.3% when running with fuel blend J+D70 at speed of 2200 min–1 compared with those values measured with jet fuel. Smoke of the exhaust was 53.1% and 1.9% higher when using fuel blend J+D10 than that of 46.9% and 70.0% measured with jet fuel at speeds of 1400 and 2200 min–1. The engine produced 34.5% more smoke from combustion of fuel blend J+D70 at the low speed of 1400 min–1, but smoke converted to be 11.3% lower when operating at a higher speed of 2200 min–1.

Opis:

Recent years have brought significant progress in the field of hybrid vehicles. Today, almost all major manufacturers offer this type of cars for their clients. Hybrid drives have lower fuel consumption and less emission of toxic gases. These benefits have led to the rapid popularization of hybrid cars on the global market. The growing demand for economical vehicles leads to increased work of engineers on new improvements. The biggest drawback of such drives is their high cost of purchasing. The result is lack of small urban car with such a powertrain. Following article describes the prototype of hybrid powertrain designed for small car with diesel engine. Vehicle design is based on the construction of Fiat Panda. The project includes construction of the prototype vehicle with eAWD powertrain. Prototype vehicle will be used for research into finding the optimum powertrain control algorithms. Test results will determine possible fuel savings and economical benefits of using hybrid cars in urban driving cycle. Research results will be compared with the results of simulations carried out Matlab/Simulink program. This comparison will confirm the correctness of simulation algorithms that can be used in the process of optimizing the drive control program. Research results confirm the correctness of simulation algorithms that can be used in the process of optimizing the drive control program.

Opis:

The largest amount of air pollutants is produced by the combustion of fossil fuels (coal, lignite, petroleum, natural gas, etc.). Such combustion releases huge amounts of greenhouse gases into the atmosphere (including carbon oxides (CO, CO2), sulphur oxides (SO2, SO3), nitrogen oxides (NO, NOx)) and dust, ashes and soot. Transportation is a significant share of the air pollution, mainly wheel-based transportation. The combustion process in diesel engine is very complex physico-chemically and varies in time. The process is accompanied by simultaneous exchange of heat and mass and chemical reactions. The development of internal combustion engines is made towards meeting of the increasingly stringent requirements for toxic exhaust emissions, reduction of fuel consumption, and preservation of Earth's natural resources. The problem to solve in modern diesel engines is the emission of toxic compounds. One way to reduce emissions is to use a catalytic converter positioned directly in the combustion chamber of an internal combustion engine. The aim of this analysis is assessment of toxic emissions of a diesel engine with an internal catalyst. Qualitative assessment of engine emissions was determined by comparing test results of an engine with ceramic-ally coated valves against one with just conventional valves (commercial valves - without a ceramic coating). The study utilized a fourcylinder 1.9 TDI VW engine. It was expected that the use of glow plugs with an active coating would reduce the release of toxic compounds.

Opis:

To make clear the feasibility and influence factors of diesel fuel autothermal reforming to hydrogen, PdCeCr-FeCu/Al2O3 catalyst was prepared by equivalent-volume impregnation method. Experimental facility based on an adiabatic tubular reactor with preheating section was designed and set up, the behaviors of diesel reforming to hydrogen with straight-run diesel as a raw material according to the analysis of the components were studied. Diesel oil reforming over a catalyst for hydrogen production was analyzed using an adiabatic tubular reactor with a preheating section that was designed and built in-house. The operating conditions were optimized. Under the suitable operating conditions, viz., catalyst bed inlet temperature of 700°C, diesel liquid space velocity of 0.24 h–1, water-carbon ratio of 20, and oxygen-carbon ratio of 0.6, the hydrogen yield reached 28.3 (mol/mol).

Opis:

In Mexico, one of the principal natural resources is oil, however, the activity related to it has generated hydrocarbon spills on agricultural soils. The aim of this study was to evaluate the biodegradability of diesel by means of indigenous bacteria isolated from agricultural soil contaminated with 68 900 mg kg-1 diesel. We examined indigenous bacterial strains in agricultural soils contaminated with diesel from Acatzingo, Puebla, Mexico. We performed a physicochemical soil characterization, and a bacterial population quantification favoring sporulated bacteria of the genera Bacillus and Paenibacillus taken from the study site. Six bacterial strains were isolated. The identification was made based on the 16S rRNA gene and API systems. The tolerance and biodegradation capacity in diesel were determined at 4 000 to 24 000 mg L-1 of diesel. Residual concentrations of diesel were determined by GC-FID. Soil contaminated with diesel alters the concentrations of organic matter, phosphorus and nitrogen. Analysis of soil samples showed heat resistant bacterial populations of 106 cfu g-1 dry soil. Six strains from soil pollution were identified – Pseudomonas stutzeri M1CH1, Bacillus pumilus M1CH1b, Bacillus cereus M1CH10, Bacillus subtilis M1CH15a, and Paenibacillus lautus strains M1CH19 and M1CH27. These bacteria showed different degradation behavior. Bacillus pumilus M1HC1b and Paenibacillus lautus M1CH27 use diesel oil as the sole carbon source. Bacillus pumilus degraded high concentrations of diesel (24 000 mg L-1), while for Paenibacillus lautus it became toxic and the degradation was less.

Opis:

To make clear the feasibility and influence factors of diesel fuel autothermal reforming to hydrogen, PdCeCr-FeCu/Al2O3 catalyst was prepared by equivalent-volume impregnation method. Experimental facility based on an adiabatic tubular reactor with preheating section was designed and set up, the behaviors of diesel reforming to hydrogen with straight-run diesel as a raw material according to the analysis of the components were studied. Diesel oil reforming over a catalyst for hydrogen production was analyzed using an adiabatic tubular reactor with a preheating section that was designed and built in-house. The operating conditions were optimized. Under the suitable operating conditions, viz., catalyst bed inlet temperature of 700°C, diesel liquid space velocity of 0.24 h–1, water-carbon ratio of 20, and oxygen-carbon ratio of 0.6, the hydrogen yield reached 28.3 (mol/mol).

Opis:

The article presents the test results of the single cylinder compression ignition engine with common rail injection system operating on biofuels and conventional diesel blends with hydrogen. Two types of liquid fuels were tested: blend of the 7% Rapeseed Methyl Ester (RME) with conventional diesel fuel and Neste Pro Diesel – blend of the 15% Hydrotreated Vegetable Oil (HVO), produced by Neste Oil Corporation with conventional diesel fuel. The purpose of this investigation was to examine the influence of the hydrogen addition to biofuels and diesel blends on combustion phases, autoignition delay, engine performance efficiency and exhaust emissions. Hydrogen fraction was changed within the range from 0 to 43% by energy. Hydrogen was injected into the intake manifold, where it created homogeneous mixture with air. Tests were performed at both fixed and optimal injection timings at low, medium, and nominal engine load. After analysis of the engine bench tests and simulation with AVL BOOST software, it was observed that increasing hydrogen fraction shortened the fuel ignition delay phase and it affected the main combustion phase. Moreover, decrease of carbon monoxide (CO), carbon dioxide (CO2) and smoke opacity was observed with increase of hydrogen amounts to the engine. However, increase of the nitrogen oxide (NOx) concentration in the engine exhaust gases was observed.

New Diesel exhaust gas aftertreatment systems, with DPF*) and deNOx (mostly SCR) inline application are very important step towards zero emission Diesel fleet. Solid quality standards of those quite complex systems are urgently necessary to enable decisions by several authorities. The Swiss Federal Office of the Environment BAFU and the Swiss Federal Roads Office ASTRA decided to support further activities of VERT to develop appropriate testing procedures and to define the quality criteria. The present report informs about the international network project VERT *) dePN (de-activation, de-contamination, disposal of particles & NOx), which was started in Nov. 2006 with the objective to introduce the SCR-, or (DPF+SCR)-systems in the VERT verification procedure. Examples of results with some investigated systems are given. The most important statements are: - the investigated combined aftertreatment systems (DPF+SCR) for dynamic engine application efficiently reduce the target emissions with deNOx-efficiency up to 92% (if operated in the right temperature window) and filtration efficiency based on particle count up to 100%, - the average NOx conversion rate at transient operation (ETC) depends strongly on the exhaust gas temperature profile and the resulting urea dosing control, - the NP filtration efficiency, which is verified at stationary engine operation is perfectly valid also at the transient operation. The present results will be confirmed in the further project activities with other systems and with different testing cycles. A special attention will be paid to the operational profiles, which are representative for low emissions zones LEZ.

For several years, research is underway to fuels derived from natural sources, which can partially or completely replace the fuel from crude oil. Such fuels are called non-conventional, alternative or substitute. As a substitute fuels commonly used in CI engines can provide liquid fuels of vegetable origin or another, and gaseous fuels. In the past decade, used vegetable oil methyl esters (FAME), Poland - rapeseed oil esters. Currently, notes the trend of so-called withdrawal biodiesel, including the opinion of the speaker because of the negative effect of that not only the fuel injection equipment, as well as CI engine performance. This paper presents the results of the influence the content of FAME (vegetable oil methyl esters) in diesel oil for power, torque, and the content of harmful substances in exhaust gases CI engine. These results were related to the obtained with the engine running only on pure diesel oil. The results were obtained on test bed for engine and for car.

With 70% of all locomotives still being powered by diesel and most of the locomotives being older than 30 years, the railway industry must urgently seek environmentally friendlier and economically more attractive alternatives to diesel fuel. Dual-fuel systems once installed on diesel locomotives, allow substituting most diesel fuel with much cheaper and cleaner gas fuels – biogas, natural gas, and syngas – without the necessity for large capital investments. This article describes a case of dual-fuel conversion of a S200/CHME3 series diesel locomotive, introducing to the system specifics, certification procedure, gas refueling infrastructure, as well as outlining the main economic and technical results. The article concludes by outlining the dual-fuel perspectives in the Polish railway industry and estimates the economic and ecological benefits its implementation can bring.

This paper presents the HiFORS continuously rate shaping injector for injection pressures of 2500 bar and above developed by FEVGmbH and the Institute for Combustion Engines, RWTH Aachen University. The development process from concept definition to hydraulic and deisgn layout, material choice and manufacturing is discussed. The hydraulic operating properties are verified by injection test rig investigations. Optical investigations are conducted in an optically accessible high pressure, high temperature chamber using shadowgraphy and OH chemoluminescence detection, thereby capturing both liquid and gaseous penetration as well as combustion areas. Single cylinder investigations are carried out at a 0.4 dm³ research engine in different operating points from low part load to full load. Compared to a serial production piezo injector, base measurements using conventional square injection profiles already show reduced combustion noise at improved NO_x-soot trade-off as well as lowered HC and CO emissions. Detailed investigations at part load operating points explore the potential of different continuous rate shaping patterns, while the injector’s high injection pressure capability of up to 2500 bar and its influence on engine performance is tested at full load operation points.

This article presents methods of acquisition of information from vehicle electronic components, with the purpose of its use to control the additional devices. These additional devices can comprise an LPG fitting, which was installed on a tested vehicle. Also, the way of modifying the contents of the engine control unit has been shown in order to examine the influence of the serial settings of the injection timing. Information that can be obtained from the CAN (Controller Area Network) allow for the lack of interference with the original manufacturer wiring, not disturbing the analogue signals at the same time. Modification of controller memory contents enables the improvement of performance parameters, especially in the case of the compression-ignition engine being fuelled with the addition of LPG. In the Summary section, the dynamometer test results of the modified vehicle have been presented. The tests were conducted for different control parameters during powering with Diesel fuel exclusively, as well as with the addition of LPG.

Informacje, które można pozyskać z sieci CAN pozwalają na brak ingerencji w fabryczną instalację elektryczną, nie zakłócając tym samym sygnałów analogowych. Modyfikacja zawartości pamięci sterownika pozwala na poprawę parametrów użytkowych, zwłaszcza w przypadku zasilania silnika o zapłonie samoczynnym dodatkiem LPG. W podsumowaniu zaprezentowano wyniki badań hamownianych modyfikowanego pojazdu. Badania przeprowadzono dla różnych parametrów sterowania podczas zasilania wyłącznie olejem napędowym jak również z dodatkiem LPG.

The article deals with the effects made by using various n-butanol-diesel fuel blends on the combustion history, engine performance and exhaust emissions of a turbocharged four-stroke, four-cylinder, CRDI 1154HP (85 kW) diesel engine. At first, load characteristics were taken when running an engine with normal diesel fuel (DF) to have ‘baseline’ parameters at the two ranges of speed of 1800 and 2500 rpm. Four a fossil diesel (class 1) and normal butanol (n-butanol) fuel blends possessing 1 wt%, 2 wt%, 3 wt%, and 4 wt% (by mass) of n-butanol-bound oxygen fractions were prepared by pouring 4.65 wt% (BD1), 9.30 wt% (BD2), 13.95 wt% (BD3), and 18.65 wt% (BD4) n-butanol to diesel fuel. Then, load characteristics were taken when an engine with n-butanol-oxygenated fuel blends at the same speeds. Analysis of the changes occurred in the autoignition delay, combustion history, the cycle-to-cycle variation, engine efficiency, smoke, and exhaust emissions NOx, CO, THC obtained with purposely designed fuel blends was performed on comparative bases with the corresponding values measured with ‘baseline’ diesel fuel to reveal the potential developing trends.

Opis:

As a part of the research work done on the engine URSUS 4390 which aimed at increasing power while reducing exhaust gas emissions, intake channels in the head, shape of the combustion chamber and compression ratio were modified. Proper injection equipment was selected and atomizer nozzles were constructed. In the first phase of the research, toroidal combustion chamber was located in factory design location. In the article there are presented results of exhaust gas emissions in selected operating points of engine URSUS 4390 for various positions of experimental combustion chamber. An innovative method of changing the position of the combustion chamber related to the piston axis was developed. A rotating insert with eccentrically extruded combustion chamber was mounted in piston axis. Rotation of the insert by a given angle resulted in displacement of combustion chamber around the axis of rotation. For each particular position of combustion chamber, concentration of toxic flue gas components and smoke index was measured at full load with rotational speed of 1400 and 2000 rpm. Proposed piston construction with rotating insert allowed to significantly decreasing duration of the research, which aimed at verification of combustion chamber relative location to injector and inlet nozzle. This way the necessity of construction of new sets of pistons and lapping them each time was avoided. As a result of the work, 11 locations of combustion chamber were tested. The study allowed picking the position of combustion chamber, which guarantees lowest emissions of toxic flue gas components.

It is oblivious, various properties of fuels cause different thermal loads of engines. Question is, how big is this effect and what fuel compound and its property play insignificant part. This paper is focused on problem of quality of diesel commercial fuels in Polish market and it is a challenge to find answer for question mentioned above. The academic staff from Wroclaw University of Technology organized tests with different commercial fuels. Chemical and physical properties of these fuels were studied and used for investigation to define relationships between them and thermal load during simulation process. All researches were done in the lab of Division of Motor Vehicles and Internal Combustion Engines at the Wroclaw University of Technology. Tests have showed differences in chemical and physical properties of fuels, but there is no statistics effect on engine parameters. Results have not also pointed any important differences in thermal loads of engine VW1,9 TDI and its components according to different physical and chemical properties of tested fuels. It is probably because there are differences of calorific values from one side but from other hands various density and specific fuel consumption compensated these differences. To burn unit of fuel contains higher level of oxygen, engine needs lower amount of air, so it gives, for the same fuelling system, lean mixture. It causes higher temperature of exhaust gases and a bit higher exhaust losses

Opis:

The paper presents results of investigation of cylinder liners wear. The investigation was carried out on diesel engines during long lasting operation in 5 motor trucks. Cylinder diameters were measured in two perpendicular planes on four depths using 2-point bore gauge, after removal of the cylinder head. Measurements were made every 50 000 km of vehicle mileage. Such methodology of measurements enabled to determine time course and wear profile of the cylinder liners (wear value in relation to the direction and height of the liner). It was stated that increments of diameter during the first period of operation are several times higher than during the later periods, when the wear intensity is constant. It was also found that wear of the cylinder liner in the plane perpendicular to the engine axis is bigger than in the parallel plane, and that wear in the upper part of the liner is twice as big as in its middle part. Measurement scheme for the cylinder liner; histogram of cylinder liner diameters obtained in measurements after the technological running-in of the engine after mileage of 0, 50,000 km, 150,000 km and 250,000 km, wear profiles of cylinder liners in the two directions at different vehicle mileages are presented in the paper. Estimated profiles of the cylinder liner wear will be used as input data for the calculations of the blowby intensity with the use of mathematical model of PRC set.

Opis:

Compression ignition engines have no possibility for self-regeneration of DPF and regeneration requires additional energy for soot combustion (additional fuel or electric energy) after some period of the engine work as a result of closing of substrate pores by soot. The innovation method takes into account a self-regeneration of diesel particle filter by use of special heat recovery system. The paper shows one of possible design of DPF self-regeneration. The exhaust temperature behind the turbine and catalytic converter is very low and for an increasing of gas temperature before DPF, the heat from soot combustion can be used. The preliminary studies show a possibility of using the special design of DPF with heat recovery system. The paper presents results obtained from simulations based on one-dimensional model of such system and analysis of increasing the heat recovery ratio by change of geometry of DPF. The gas heat exchange formulas between DPF and the heat exchange model are partly included in the paper. The preliminary results of calculations show the possibility of increase of exhaust gases in front of DPF about 20%, which enables a continuous regeneration of DPF. Heat recovery ratio is depends on soot combustion rate on the wall of DPF monolith. The method enables to recover some part of energy which is lost in the conventional DPF. The paper is a part of further work in European project FP6 IPSY.

Opis:

In this paper molybdenite flotation using microemulsified collector was reported. The flotation performance of microemulsified collector and conventional diesel was compared. This study is a prelimi-nary investigation which uses pure molybdenite mineral in a modified Hallimond tube. The pH tests showed that the highest recovery of molybdenite in the presence of diesel and microemulsion was ob-tained at pH=6, reaching the recoveries of 93% and 90%, respectively. In the case of obtaining similar results, it was observed that the microemulsion consumption was lower in comparison to diesel. In the flotation tests with microemulsified collector the recovery slightly decreased because too large collector amount caused formation of more unstable bubbles. The contact angle measurements showed that the microemulsified collector was more effective for increasing the hydrophobicity of molybdenite surface. An adsorption model was proposed and it was suggested that the non-ionic surfactant present in the mi-croemulsified collector formed a continuous bimolecular layer, resulting in the increased surface hydro-phobicity. The accomplishment of this research demonstrated the viability of the use of microemulsified collector in molybdenite flotation, attempting to simplify the molybdenite flotation process, especially replace the conventional emulsified collector with high energy consumption and difficult storage.

Opis:

Introduction. Diesel oil is a mixture of hydrocarbons. These compounds are widely used in everyday life. Oral exposures are most often accidental and affect mainly children, but they also happen in adults. Oral ingestion may lead to aspiration of pulmonary alveoli which may cause necrotizing pneumonia. Aim. The aim of the study is to assess te severity of diesel oil intoxication on an example of a presented case. Methods. The analysis of the clinical patient history and review of available literature. Results. A 27 year old patient was admitted to the toxicology department due to accidental diesel poisoning. Patient drank a small amount diesel oil, then suffered nausea and vomiting, which resulted in aspiration of diesel to respiratory system. During hospitalization focal necrotizing pneumonia was diagnosed. Patient was treated with intensive specific pharmacotherapy. On the 11th day of stay, the patient was discharged with recommendation of control in the pulmonological and toxicological clinic and chest x-ray examination in order to diagnose the suspicious oval change discovered in the right lobe during hospitalization. Conclusion. First toxicity symptoms are non-specific, so well collected anamnesis is crucial. Complications of hydrocarbon ingestion can be a threat to patient’s life. Due to rarity of the problem, there are no clearly defined treatment guidelines

Results of modelling of thermal cycle of turbocharged compression ignition IC engine are presented. The object of investigation was a 6CT107 turbocharged auto-ignition internal combustion engine powered by diesel oil, installed on an ANDORIA-MOT 100 kVA/ 80 kW power generating set in a portable version. The performed simulations of the combustion process have provided information on the spatial and time distributions of selected quantities within the combustion chamber of the test engine. The numerical analysis results have been juxtaposed with the results of indicating the engine on the test stand. Modelling of the thermal cycle of an auto-ignition piston engine in the AVL FIRE was carried out within the study. Advanced numerical submodels were used to analysis of combustion process, such as: Extended Coherent Flame Model (ECFM-3Z), turbulence model k-zeta-f, injection submodels with evaporation, collisions, coalescence and other. Intake and exhaust processes were included during modelling. This resulted in a lot of information about the intake, fuel mixing, ignition process and the exhaust process. Results of modelling were compared with results from real engine.

Opis:

Current and future air quality is a worldwide concern, which has resulted in both a continuous tightening of emissions legislation for vehicles and a parallel tightening of fuel specifications. The automotive and oil industry across the globe especially in EU, USA and Japan have in each case made considerable efforts to understand the relationship between vehicle emissions, urban air quality, engine technologies and fuels, and to meet the more and more stringent legislation. The supply of automotive fuels today is based almost entirely on petroleum.The quality requirements of diesel fuels become more and more stricter and it will continue in the next decades, because the clean engines need clean fuels. Therefore, fuels of low emission become significant factor in reducing toxic emission which pollutes the environment. With the introduce of low sulfur diesel fuel, the effect of sulfur become less significant. Other fuel properties such as aromatics content i.e. composition thus becomes more important. From this aspect it is investigated the affect of simultaneous addition of mono+-, di+ - and tri+-aromatics into low-sulfur diesel fuel. Obtained results show that aromatics composition has the effect on diesel exhaust emission.

Opis:

The use of diesel oil and methanol mixture in a Diesel engine requires modernization of old fuel injection control systems or development of new ones. Therefore, few options of structural solutions of the fuel injection system have been developed. The objective of the paper was to develop a structure of control elements of fuel injection in a Diesel engine which works with diesel oil and methanol mixtures, diesel oil and biogas mixtures, to check their practical utility and formulate indications. The control systems of multi-fuel Diesel and gas engines as well as two types of submerged high-pressure regulators were discussed. Characteristics of engine power, torque, unit and hour fuel consumption in the function of rotational speed with the use of Diesel D-21A1 engine were defined. The impact of methanol addition to diesel oil on the power and other performance indexes of a Diesel engine were determined. Two structural variants of the submerged fuel regulator were positively evaluated. The described solutions obtained a patent right and a patent protection and have been introduced to production in the Flow Machines Unit in Nikopol (Russia) and are used by the Central Scientific and Research Institute of Diesel Fuels in Saint Petersburg with work on improvement of Diesel engines.
Zastosowanie mieszanki oleju napędowego i metanolu w silniku Diesla wymaga modernizacji starych lub opracowania nowych systemów regulacyjnych wtrysku paliwa. W tym celu opracowano kilka wariantów rozwiązań konstrukcyjnych systemu wtrysku paliwa. Celem pracy było opracowanie konstrukcji elementów regulacyjnych podawania paliwa w silniku Diesla pracującym na mieszankach oleju napędowego i metanolu oraz oleju napędowego i biogazu, sprawdzenie ich praktycznej przydatności i sformułowanie zaleceń. Omówiono systemy regulacyjne silnika Diesla wielopaliwowego, gazowego oraz dwa typy nurnikowych regulatorów wysokociśnieniowych. Sporządzono charakterystyki mocy silnika, momentu obrotowego, jednostkowego i godzinowego zużycia paliwa w funkcji prędkości obrotowej z użyciem silnika Diesla D-21A1. Określono wpływ dodatku metanolu do oleju napędowego na moc i inne wskaźniki eksploatacyjne silnika Diesla. Opracowane dwa warianty konstrukcyjne zespołu nurnikowego regulatora paliwowego uzyskały pozytywną ocenę. Opisane rozwiązania uzyskały świadectwa autorskie oraz ochronę patentową i zostały wdrożone do produkcji w Zakładzie Aparatury Przepływowej w Nikopolu (Rosja) i są wykorzystywane przez Centralny Naukowo-Badawczy Instytut Paliw Diesla w Sankt Petersburgu przy pracach nad doskonaleniem silników Diesla.

Opis:

The uncertainty in the supply of crude oil, increasing the number of vehicles and rising air pollution, especially in urban areas, has prompted us to look for alternative fuels. It is understood that using Compressed Natural Gas (CNG) in IC engines could be a mid-term solution to these problems. It is well established that CNG has better combustion characteristics and low emissions compared to conventional gasoline and diesel fuel. In the present study, an experiment was conducted to evaluate the engine performance and exhaust emissions using various percentages of CNG in dual fuel mode. CNG was mixed in the intake manifold’s air stream, and diesel was injected after the compression of the CNG air mixture. This paper presents experimental results of 40%,60%, and 80% CNG in the air stream. Engine performance and emissions are presented and discussed at a speed of 1200 rpm to 1500 rpm in steps of 50 rpm. The results of the experiments showed that adding CNG to diesel engines in dual-fuel combustion significantly impacted performance and emissions. Compared to single diesel fuel combustion, dual fuel combustion increases brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) at all CNG energy shares and engine speeds. Carbon monoxide (CO) and hydrocarbon (HC) emissions were increased, while nitrogen oxide (NOx) and smoke opacity were decreased in dual fuel combustion compared to single diesel fuel.

Opis:

W artykuleopisano wyniki badań wybranych właściwości fizykochemicznych mikroemulsji wodno–paliwowych, które można zastosować do zasilania silników o zapłonie samoczynnym. Badania dotyczyły oleju napędowego, do którego wprowadzono odpowiednie surfaktanty oraz wodę w ilości 4 i 8% wagowo (m/m). W celu uzyskania mikroemulsji zastosowano dwa rodzaje niejonowych związków powierzchniowo czynnych tj. alkohol laurylowy oksyetylenowany 3 molami tlenku etylenu (Laureth – 3) oraz alkohol laurylowy oksyetylenowany 7 molami tlenku etylenu (Laureth – 7). Wprowadzenie tych związków chemicznych oraz wody do oleju napędowego pozwoliło uzyskać mikroemulsje paliwowe, które w niniejszej pracy oznaczono kodem L4 i L8. Średnica cząstek fazy rozproszonej w oleju napędowym zawiera się w zakresie 4–100 nm. Z tego powodu obydwie badane mikroemulsje są transparentne i stabilne termodynamicznie. Ich gęstość jest nieznacznie większa (o ok. 1%) w stosunku do oleju napędowego. Zauważono wyraźny wpływ wody oraz zastosowanych surfaktantów na wzrost lepkości mikroemulsji oraz jej temperatury zapłonu w stosunku do oleju napędowego. Jednocześnie badane mikroemulsje charakteryzowały się mniej korzystnymi właściwościami niskotemperaturowymi, co może utrudnić ich zastosowanie w warunkach zimowych.
Paper presents research results of selected physicochemical properties of water – fuel microemulsion, which can be used as a fuel for a diesel engines. Researches were carried out for a diesel oil blended with selected surfactants and water at 4 and 8 % by weight. Tested microemulsions contained a two kinds of nonionic surfactants, ie., lauryl alcohol ethoxylates with 3 moles of ethylene oxide (Laureth - 3) and a lauryl alcohol ethoxylates with 7 moles of ethylene oxide (Laureth - 7). The addition of these chemicals and water to the diesel oil allows to formulate a fuel microemulsions marked by a code L4 and L8. The particle diameter of the dispersed phase in the diesel oil is in the range of 4-100 nm. For this reason, both tested microemulsions are thermodynamically stable and transparent. Their density is slightly greater (approx. 1%) compared to diesel oil. It was observed an impact of water and surfactants on increasing the microemulsions viscosity and the ignition temperature compared to diesel oil. At the same time the low temperature properties of tested microemulsions wereless favorable, which may hinder their use in winter conditions.

Opis:

With the implementation and expansion of international sulfur emission control areas, effectively promoted the marine low sulfur diesel fuel (MLSDF) used in marine diesel engines. In this study, a large low-speed, two-stroke, cross-head, common rail, electronic fuel injection marine diesel engine (B&W 6S35ME-B9) was used for the study. According to diesel engine’s propulsion characteristics, experiments were launched respectively at 25%, 50%, 75%, 100% load working conditions with marine low sulfur diesel fuel to analyze the fuel consumption, combustion characteristics and emissions (NOx, CO2 , CO, HC) characteristics. The results showed that: Marine diesel engine usually took fuel injection after top dead center to ensure their safety control NOx emission. From 25% to 75% load working condition, engine’s combustion timing gradually moved forward and the inflection points of pressure curve after top dead center also followed forward. While it is necessary to control pressure and reduce NOx emission by delaying fuel injection timing at 100% load. Engine’s in-cylinder pressure, temperature, and cumulative heat release were increased with load increasing. Engine’s CO2 and HC emissions were significantly reduced from 25% to 75% load, while they were increased slightly at 100% load. Moreover, the fuel consumption rate had a similar variation and the lowest was only 178 g/kW·h at 75% load of the test engine with MLSDF. HC or CO emissions at four tests’ working conditions were below 1.23 g/kW·h and the maximum difference was 0.2 or 0.4 g/kW·h respectively, which meant that combustion efficiency of the test engine with MLSDF is good. Although the proportion of NOx in exhaust gas increased with engine’s load increasing, but NOx emissions were always between 12.5 and 13.0 g/kW·h, which was less than 14.4 g/kW·h. Thus, the test engine had good emissions performance with MLSDF, which could meet current emission requirements of the International Maritime Organization.

Opis:

W artykule przedstawiono wyniki badań z zakresu oceny wpływu składu mikroemulsji wodno-paliwowej na opóźnienie jej samozapłonu w silniku o zapłonie samoczynnym. W celu przygotowania mikroemulsji wykorzystano standardowy olej napędowy oraz surfaktanty/ko-surfaktanty na bazie alkoholu laurylowego. Do takiej mieszaniny wprowadzono wodę destylowaną w ilości 4 i 8 % (m/m). Uzyskane w ten sposób mikroemulsje L-4 i L-8 wykorzystano do przeprowadzenia badań silnikowych. Wyniki tych badań wskazują, że zastosowanie wody w testowanych paliwach mikroemulsyjnych nie spowodowało zwiększenia wartości kąta opóźnienia samozapłonu w stosunku do silnika zasilanego olejem napędowym.
Paper presents an impact of the water-fuel microemulsion composition on self-ignition delay angle in the diesel engine. Tested microemulsions were prepared by blending of regular diesel oil and surfactant/co-surfactant based on the lauryl alcohol. Then to the mixture a distilled water was added in ratio of 4 and 8 % by mass. These microemulsion fuels were used for the engine research. Their results indicate that the value of selfignition delay angle calculated for microemulsions is comparable or slightly lower when compare to the diesel oil.

Opis:

W artykule przedstawiono wyniki badań dotyczące określenia wartości wybranych właściwości fizykochemicznych mikroemulsji paliwowych. Badania przeprowadzono dla oleju napędowego zawierającego 4 i 8 % (m/m) wody. Jako surfaktant zastosowano olej rycynowy oksyetylenowany siedmioma molami tlenu etylenu. Natomiast jako kosurfaktant wykorzystano olej rycynowy polioksyetylenowany czterdziestoma molami tlenu etylenu. Uzyskane wyniki w zakresie oceny wybranych właściwości fizykochemicznych tj.: gęstości, lepkości kinematycznej, temperatury zapłonu, temperatury krzepnięcia oraz temperatury blokowania zimnego filtra potwierdziły wstępną przydatność opracowanych mikroemulsji jako paliwa dla silników o zapłonie samoczynnym.
Paper presents research results of selected physicochemical properties of water-fuel microemulsion, that can be used as a fuel for a diesel engines. Tests were carried out for a diesel oil blended with selected surfactants and water at 4 and 8 % by mass. Tested microemulsions contained a surfactant and cosurfactanst, ie., PEG-40 and PEG-7. The addition of these chemicals and water to the diesel oil allows to formulate a fuel microemulsions marked by a code C4 and C8. Both tested microemulsions are thermodynamically stable and transparent. Their density is slightly greater (approx. 1%) compared to diesel oil. It was observed an impact of water and surfactants on increasing the microemulsions viscosity and the ignition temperature compared to diesel oil. At the same time the low temperature properties of tested microemulsions were less favorable, which may hinder their use in winter conditions.
