Experimental Investigation on Performance and Emission Characteristics of Diesel Engine Fueled With Blends of Karanja Oil Methyl Ester

Biodiesel are becoming popular as alternative eco-friendly fuel now days. The petroleum product requirement is going on increasing day by day in India with limited resources in the oil pool. Crisis of petroleum fuel and import of fossil fuel is giving a high impact on the economy and development. Besides the economy and development, fossil fuel also leads to a major problem like global warming and climatic change. The emission of harmful gasses like CO, NOx, CO2, and smoke density causes acid rain, health hazard and also global warming. The high oil price, environmental concern and supply instability put many researchers to go for alternative fuel i.e. biodiesel. Biodiesel is part of the solution which reduced many of the problems. The objectives of this study are the production process, fuel properties, oil content, engines testing and performance analysis of biodiesel from karanja oil which is known as Karanja oil methyl ester (KOME). Engine tests have been carried out in a water cooled four stroke diesel engine and experimental investigation have been carried out to examine properties, performance and emission of different blends of KOME. The study reveals that the emission parameters are better for biodiesel blends fuel compared to diesel. Whereas, brake thermal efficiency and brake specific fuel consumption parameters are inferior compared to diesel.
