Comparative Performance and Emission Analysis of A Diesel Engine Using JOME, KOME and MOME Blends

Abstract

Fossil fuel resources are decreasing because of increasing use and causing effects on the environment. Therefore, renewable, carbon neutral alternative fuels are required for environmental and economic sustainability. A potential renewable alternative fuel is biodiesel, which is produced from vegetable oils and animal fats. Biodiesel comprises mono alkyl esters of long chain fatty acids. In the present paper, experimental investigation is carried out to examine performance and emissions of different blends of Jatropha oil methyl ester, Karanja oil methyl ester and Mahua oil methyl ester. Results indicated that Jatropha has closer performance to diesel. Karanja has equally good thermal efficiency with blends other than B100. Mahua oil ester has the lower efficiency with 50% load. Exhaust gas emissions like hydrocarbons, carbon monoxide, oxides of nitrogen and smoke opacity were measured using a gas analyzer. Results indicate that biodiesel blends upto 20% with diesel can be used as an alternative fuel in existing compression ignition engine with no modification.
