Abstract : Present work deals with testing performance of CIengine with different blends of non-edible oil as well as their methylesters with petrodiesel.

To improve the performance of parameters like brake thermal efficiency, specific fuel consumption, brake power and reduction in brakes specific fuel consumption, especially at higher load.

•The methods used to reduce viscosity are; blending, emulsification,pyrolysis and transesterfication.

•To conduct the performance on IC engine the following blended oils will be used -JATROPHA -PONGAMI
