Performance Analysis of IC Engines with Bio-Diesel Jatropha Methyl Ester (JME) Blends



Petroleum products resources are limited  and their consumption rate is increasing  very fast with technological  development  since  the  last  two  decades.  The  emissions  from  the  usage  of  these petroleum products pollute the environment considerably. Jatropha oil is one of the renewable energy resources which are easily available in India. This study investigates the percentage substitution of jatropha methyl ester blends to diesel as fuel for automobiles and other industrial purposes. The study details the analysis of the performance and emission characteristics of the jatropha methyl esters and its comparison with petroleum diesel. The tests were carried out on a 3.7 KW single cylinder, direct injection and a water-cooled diesel engine. The fuels used were neat jatropha methyl ester, diesel and different blends of the methyl ester with diesel. The experimental result shows that 20% of the blend shows  better  performance with  reduced  pollution.  The  analysis  shows  that jatropha  methyl  ester blended biodiesel is a good substitute for pure diesel.
