The Effect of Biodiesel on Combustion, Performance and Emission Characteristics of DI Diesel Engine

Biodiesel fuels play an important role in addressing issues such as food security and environmental pollution. Diesel oil fuel and biodiesel-diesel blends (including B5S, B10S, and B100S which are produced from the rubber seed oil by supercritical methods) are going to be examined in this study. Engine performance, emissions and combustion characteristics of diesel engine were studied. The results of this experimental research show that the oxygen content of biodiesel helps to improve combustion, reduce ignition delay and decrease a significant amount of smoke density emitted from the engine; however, improved combustion has resulted in a slight increase in the amount of NOx. The results from this study have made contribution to the development and use of biodiesel fuel.
