Engine Performance and Emission having Jatropha Diesel Blend

Apurba Layek

Abstract


The performance of a four stroke, single cylinder, direct injection CI engine is evaluated having fuel as neat jatropha-diesel blend in proportion 2:1 on a volume basis. The experimentations were conducted to test engine performance and emission characteristics at throttle settings of 25%, 50%, 75% and 100% and variable loads covering under load to overloading of engine operation. The effect of jatropha blend on engine brake power, brake thermal efficiency and specific fuel consumption were observed at different loads and throttle openings along with exhaust emissions and exhaust gas temperatures. Compared to jatropha blend diesel provides better performance for entire operating range (of loads and throttle openings) but effect of varying load /throttle settings on performance characteristics are of similar nature. The jatropha blend produces lower hydrocarbon and NOx emission, highlights the positive aspects of combustion and the allowance of higher effective compression ratio of the blend.
