Abstract

Determine engine performance of a naturally aspirated direct injection diesel engine fueled with diesel and pungam methyl ester blend (PME20). Comparison of performance was done for different values of compression ratio, injection pressure and injection timing to find best possible combination for operating engine with PME20. It is found that the combined compression ratio of 19:1, injection pressure of 240 bar and injection timing of 27°bTDC increases the brake thermal efficiency. From the investigation, it is concluded that the both performance was considerably improved for PME20 compared to diesel.
