Study on Emission Index of Jatropha Based Bio Diesel

In the current scenario world petroleum reserve is getting depleted and there is an urgent need to find an alternative fuel, which has similar characteristics of conventional fuels. Jatropha based bio diesel is an alternative, which can be easily produced and made commercial. Also, bio diesel can be directly used on internal combustion engine (ICE) without any modification. Study on the different cultivation methods of Jatropha Curcas plant and production methods in India have been explained in detail. The emissions of CO, PM (particulate matter), CO2 and SOx are less as compared to diesel. However, NOx emissions are high in bio diesel. The aim of this work is to find an optimum blend, which has least NOx emissions, and to find the emission index of bio diesel. The blends chosen for the experiment included B20, B40, B60, B80 and B100. The optimum blend with least NOx emission was found to be B20 but the NOx emissions are still high compared to diesel. The emission index of NOx of all blends was calculated. The Emission Index value showed that blends B20 – B40 can be used on diesel engine without any engine modification and also with a minimum emission of NOx. Bio diesel is environment friendly and a better alternative to diesel.
