Gujral Punjab Technical University, Hoshiarpur Campus, India Taking into account the rising cost of non-renewable energy source and ecological contamination, elective fuel is required. Looking for such fuel, biodiesel has drawn everybody's consideration. Biodiesel might be an enormous substitute for a non-renewable energy source. The current paper speaks to a relative examination of the biodiesel Karanja, Mahua and Jatropha in comparison with pure diesel (D100). The three biodiesels were extracted from two-step transesterification process. Then 20 percentage blends of the biodiesels were used in CI engine separately at varying load. The Results were determined and afterwards compared on the ground of performance and emission from the engine. The outcomes demonstrate that the carbon monoxide (CO), hydrocarbon (HC), CO2 and smoke created by K20 (karanja 20% blend), J20 (jatropha 20% blend) and M20 (mahua 20% blend) are lower than diesel (D100). The brake thermal proficiency (BTE) for all the three biodiesels was found lower as comparison with D100. The brake specific fuel consumption was lowest for D100. Additionally, K20, J20 and M20 produce more NOx than diesel D100. Likewise, EGT was found highest for D100. http://pubs.sciepub.com/aees/8/6/10/aees-8-6-10.pdf biodiesel emission performance karanja Jatropha and Mahua
