TL;DR: In this paper, the analysis of the combustion, performance and emission characteristics of a direct injection diesel engine with jatropha methyl ester (JTME), diesel and their blends is presented.
Abstract: This work involves the analysis of the combustion, performance and emission characteristics of a direct injection diesel engine fuelled with jatropha methyl ester (JTME), diesel and their blends JTME is prepared by the alkali transesterification of Jatropha oil with methanol The combustion parameters are determined by measuring in-cylinder pressure with respect to crank angle The results show that ignition delay, maximum heat release rate and combustion duration are lower for JTME and its blends compared to diesel Though JTME and its blends recorded lower Brake thermal efficiency, they have lower tail pipe emissions as compared to diesel, except for nitrogen oxides

TL;DR: In this paper, the effects of MEA on engine's power, fuel economy, emissions and combustion characteristics were studied on a single cylinder DI diesel engine under the same speed and load conditions, the maximum cylinder pressure decreases when fueled with the blends, while the ignition delays and the combustion duration becomes shorter.
