Influence of injection timing and compression ratio on performance, emission and combustion characteristics of Annona methyl ester operated diesel engine

Abstract This study targets at finding the effects of the engine design parameters viz. compression ratio (CR) and fuel injection timing (IT) jointly on the performance with regard to specific fuel consumption (SFC), brake thermal efficiency (BTHE) and emissions of CO, HC, Smoke and NO x with Annona methyl ester (A20) as fuel. Thus A20 can be effectively used in a diesel engine without any modification. Compression ratio of 19.5 along with injection timing of 30°bTDC (before top dead centre) will give better performance and lower emission which is very close to diesel. Comparison of performance and emission was done for different values of compression ratio along with injection timing to find best possible combination for operating engine with A20. It is found that the combined increase of compression ratio and injection timing increases the BTE and reduces SFC while having lower emissions. Diesel (20%) saved, will greatly meet the demand of fuel in railways.
