20501 Engine Performance and Emission Study on Bio Fuel Using a Highly Boosted Single Cylinder Diesel Engine : Fourth Report: Combustion Characteristics by RME 50% Fuel

In present scenario researchers focusing the alternate sources of petroleum products. Based on this, current research work focused the emission study of its characteristics and potential as a substitute for Diesel fuel in CI engines. Current research biodiesel is produced by base catalyzed transesterification of rice bran oil is known as Rice Bran Oil Methyl Ester (Biofuel). In this research various proportions of Biofuel and Diesel are prepared on volume basis. It is used as fuels in a four stroke single cylinder direct injection Diesel engine to study the performance and emission characteristics of these fuels. Varieties of results obtained, that shows around 50% reduction in smoke, 33% reduction in HC and 38% reduction in CO emissions. In result discussion a different blends of the brake power and BTE are reduced nearly 2 to 3% and 3 to 4% respectively around 5% increase in the SFC. Therefore it is accomplished from the this experimental work that the blends of Biofuel and Diesel fuel can successfully be used in Diesel engines as an alternative fuel without any modification in the engine. It is also environment friendly blended fuel by the various emission standards.

This paper investigates the performance, exhaust emissions, and combustion characteristics of a dual fuel diesel engine fueled by CNG (compressed natural gas) as the main fuel. The experiments used standard ignition fuels prepared by n-hexadecane and heptamethylnonane which are used to define the ignitability of diesel combustion, and focused on the effects of fuels with better ignitability than ordinary gas oil such as fuels with higher cetane numbers, 70 and 100. Compared with gas oil ignition, a standard ignition fuel with C.N. 100 showed shorter ignition delays, and lower NOx exhaust concentrations, and engine noise. The results also showed that regardless of ignition fuel, misfiring occurred when the CNG supply was above 75%. While the CNG ratio where misfiring occurs lowered somewhat with increasing C.N., the combustion stability (defined as the standard deviation in the cycle to cycle variation of IMEP divided by the mean value of IMEP) was little influenced. In summary, the results show that the influence of the ignitability on the engine performance and emission characteristics of the dual fuel operation is relatively small when the ignition fuel has C.N., and similar to or higher than ordinary gas oil.
