Comparative Performance Study of Jatropha Methyl Ester as Diesel Oil Substitute on DI Diesel Engine With Emphasis on Vibration and Noise as Potential Engine Parameters

Abstract

Among the biomass resources, vegetable oils are observed to be good alternative fuels for use in diesel engines and are also attractive because of renewability. However, there are fundamental problems of engine performance and exhaust emissions due to high viscosity and low volatility of the pure vegetable oil. The present work aims at evaluating the performance of Jatropha methyl ester (JME) by evaluating the combustion properties and engine vibration & noise. This generates a corroborative method to ascertain the engine combustion quality, as the vibration trend developed by the engine is synonymous with the excitation generated by combustion..
