Experimental investigation on the influences of varying injection timing on the performance of a B20 JOME biodiesel fueled diesel engine / S. Jaichandar and K. Annamalai

This experimental study aims to optimize the injection timing to achieve higher performance from biodiesel fueled Direct Injection (DI) diesel engine. Experiments were performed using a naturally-aspirated single cylinder DI diesel engine equipped with a conventional jerk type injection system to st...
