Abstract

The present research work aimed to analyse the performance and emission characteristics of a single cylinder, air cooled, compressed injection diesel fuelled with Jatropha methyl ester blends with Diethyl Ether (DEE) and Isobutanol (IB) additives. Each additive was added in the proportion of 5% and 10% by volume. Experiments were conducted with diesel, B20 and B30 JME (Jatropha Methyl Ester) blends added with selected additives. With these additives, the fuel properties improved. The engine test results showed an improvement in all the performance and emission characteristics with the fuel added and with additives. B20 + 10% DEE showed a better specific fuel consumption, brake thermal efficiency and lower NOx emissions. B30 + 10% IB had shown better CO, CO2 and O2 emissions.
