Journal ArticleDOI
Combustion and performance evaluation of a diesel engine fueled with biodiesel produced from soybean crude oil.
TL;DR: In this article, the performance, emissions and combustion characteristics of the compression ignition engine of a diesel and biodiesel engine were analyzed, and the results showed that biodiesel exhibited similar combustion stages to that of diesel, however, biodiesel showed an earlier start of combustion.
Journal ArticleDOI
Experimental studies on the combustion characteristics and performance of a direct injection engine fueled with biodiesel/diesel blends
TL;DR: In this paper, the effects of biodiesel addition to diesel fuel on the performance, emissions and combustion characteristics of a naturally-aspirated DI compression ignition engine were examined, and a minor increase in brake specific fuel consumption (BSFC) and decrease in brake thermal efficiency (BTE) for biodiesel and its blends were observed compared with diesel fuel.
Journal ArticleDOI
Effect of diethyl ether and ethanol additives on the combustion and emission characteristics of biodiesel-diesel blended fuel engine.
TL;DR: In this paper, the effects of using diethyl ether and ethanol as additive to biodiesel/diesel blends on the performance, emissions and combustion characteristics of a direct injection diesel engine were evaluated.
Journal ArticleDOI
Performance and combustion characteristics of biodiesel–diesel–methanol blend fuelled engine
TL;DR: In this article, the effects of using methanol as additive to biodiesel-diesel blends on the engine performance, emissions and combustion characteristics of a direct injection diesel engine under variable operating conditions were evaluated.
Journal ArticleDOI
Effect of injection parameters on the combustion and emission characteristics in a common-rail direct injection diesel engine fueled with waste cooking oil biodiesel
TL;DR: In this article, the effects of the injection pressure and injection timing on the combustion and emission characteristics in a single-cylinder common-rail direct injection (CRDI) diesel engine fueled with waste cooking oil (WCO) biodiesel and commercial diesel fuel were investigated.
