Compression ignition engine is a popular prime mover in rural areas, particularly in the places where electrical power is not available. The rapid depletion of fossil fuel has stimulated worldwide efforts to produce alternative fuel to diesel fuel. Use of bio fuel as an alternative fuel can contribute significantly towards the twin problem of fuel crises. The fuel of bio origin may be the bio d...

Diesel is one of the fuels used in automobiles. But diesel is often adulterated with Kerosene which harms the engine and reduces the life of automobiles. An electronic technique has been developed to determine the adulteration in diesel by kerosene, in which the light is passed in an optical fiber, the cladding of which is removed over a small area, where the evanescent wave interacts with the ...

Diesel exhaust particles (DEP) contain elemental carbon, organic compounds including Polyaromatic hydrocarbons (PAHs), metals, and other trace compounds. Diesel exhaust is complex mixture of thousands of chemicals. Over forty air contaminants are recognized as toxicants, such as carcinogens. Most diesel exhaust particles have aerodynamic diameters falling within a range of 0.1 to 0.25 μm. DEP w...

investigations are carried out to evaluate the performance of a low heat rejection (lhr) diesel engine consisting of air gap insulated piston with 3-mm air gap, with superni (an alloy of nickel) crown and air gap insulated liner with superni insert with different operating conditions of crude jatropha oil with varied injection timing and injection pressure.  performance parameters of brake ther...

This paper presents the results of experimental work carried out to evaluate the distribution of cold and hot exhaust gas recirculation between cylinders in a DI diesel engine. The experiments have been conducted on a 3.99 liters turbocharged DI diesel engine under full load condition at 1900rpm in order to distinguish and quantify some effects of hot and cooled EGR with various rates on the EG...

When looking at the effects of diesel engine exhaust on the environment, it is important to first look at the composition of the exhaust gases. Over 99.5% of the exhaust gases are a  combination of  nitrogen, oxygen, carbon dioxide, and water. With the exception of carbon  dioxide, which contributes about  5% of the total volume, the diesel engine exhaust consists of  elements which are part of...

To efficiently recover the waste heat from a diesel engine exhaust, a regenerative organic Rankine cycle (RORC) system was employed, and butane, R124, R416A, and R134a were used as the working fluids. The resulting diesel engine-RORC combined system was defined and the relevant evaluation indexes were proposed. First, the variation tendency of the exhaust energy rate under various diesel engine...

Alternative fuels are intensively investigated for the replacement of the diesel fuel. Today the diesel power generators are mostly used in the various industrial companies in Iran. Therefore, it is necessary to estimate the level of performance of the diesel power generators fueled with biofuels. For the first time, in this study, the prediction of the performance of a diesel power generator m...
