Comparative Analysis of Jatropha-Methanol Mixture and Diesel on Direct Injection Diesel Engine

Impact of increasing trend in the production of automobile focuses on
the control of greenhouse gases. This should be within the limits of
different norms of emission. Alternative fuels are better than the
conventional fuel in those aspects. In this work, an attempt was made using
blends of Jatropha and methanol to run the single cylinder diesel engine
and their performance and emission were compared with the diesel. It has
yielded better results on the emission of HC, CO and CO2 and oxides of nitrogen and the data acquired by electronic system exhibit better performance results for jatropha methanol blend1. Diesel fuel is considered as base reading for comparing performance and emission characteristics of blend1 (the mixture of Jatropha 75% methanol 25%) and blend2 of (jatropha 80% methanol 20%) approximately. The result shows that jatropha methanol mixture gives better performance in high load rather than less than half load operations.
