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.

TDC
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 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 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:
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.

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.

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.

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

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.
