Experiments were conducted on a single cylinder, constant speed, vertical, water cooled CI engine fuelled with methyl esters of Jatropha oil blended with petroleum diesel for 20% volume ratio (B20). Injection timing and injector opening pressure (lOP) were changed to study their influence on performance, emissions and combustion parameters. Pressure Vs. crank angle data for 500 cycles were recorded for each operating conditions which was later analyzed to estimate the cyclic variations in combustion parameters using a computer program. It was observed that advancing the injection timing and increasing the lOP up to 220bar resulted in improved performance and reduced cyclic variations in peak heat release rate but at the cost of higher rate of pressure rise. On the emissions front an inverse behavior was observed between smoke opacity and NOx emissions with advanced injection timing and increased lOP.
