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 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:: 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.

Opis:: 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.

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.

Opis:: 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.

DPF
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:: 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.
