A Study on Reduction of Oxides of Nitrogen With Jatropha Oil Based Bio Diesel

Nitin Shrivastava, Satya Narayan Varma, Mukesh Pandey


The Continuous depleting oil resources and stringent emission norms leads to increase in interest in Biodiesel fuel. Biodiesel is a renewable fuel made from vegetable oil or animal fats. World’s maximum biodiesel is produced from edible oils, raising the concern for the global scarcity of edible oil supply. In order to defeat the situation, research has been conducted to produce biodiesel by using non-edible oils like Jatropha. Jatropha Biodiesel (JOME) is being accepted as promising renewable alternatives to diesel fuels. Jatropha Biodiesel have advantages over the conventional diesels, as they are known to produce reduced emissions like CO, HC and Smoke, but the NOx  Emission  is found to be increased. Use of the Cooled Exhaust Gas Recirculation (EGR) system is one of the most effective techniques currently available for reducing NOx. In the present study performance and emission parameters of a four stroke four cylinder diesel engine fuelled with neat Jatropha Biodiesel with cooled EGR is experimentally investigated. The study showed that the effect of increased NOx emission was found to be reduced with the EGR.
