Abstract: “Recently, non-edible oil based biodiesel fuels have more attractive among all researchers as well as government than edible sources based alternative fuels. The objective of this study is to compare the engine performance and emission results of biodiesel produced from Jatropha oil when applied in different proportions in multi cylinder diesel engine. Results revealed that biodiesel blends produce less CO (up to 52.6%) and lower HC (up to 48%) with an increase in emission of NO (up to 11.82%). Biodiesel also presented a slight increase in brake specific fuel consumption (up to 8.33%) which may be acceptable considering the reduction in exhaust emissions. The experimental results proved that biodiesel blends can be used in compression ignition engines, thereby providing a viable alternative to diesel.”
