Performances and emissions characteristics of diesel engine by using Jatropha oil

They are various fuels being investigate as a potential substitute to the present extremely pollutants in diesel which is resulting from the withdrawing marketable sources. The vegetables oil is among the alternative fuel which can be directly use in C.I engine which having more cetane number and C.V. Though, the BTE of the vegetables oil is lesser to the diesel fuel. The custom of vegetables oil can causes to the more smokes, CO and HC emission. It be due to more viscosity and less volatility of the vegetables oil.
The issue of more viscosity of vegetables oil is approach in various habits namely oil preheating, blending with other fuels, thermal cracking and transesterification. The main scope of project is to conduct an investigational analysis on the less heat rejection engine with help of raw Jatropha oil in the proportion 70:30 and diesel. The experiments conceded for the cylinder pressures when using the raw Jatropha oil and diesel. The results are obtained and specify the improved performances and emissions characteristics of engine with the Jatropha oil.
