PERFORMANCE AND EMISSION OF CI ENGINE USING BIODIESEL OF COCONUT OIL BLENDS

Nonconven tional energy source is one of the fast growing science in which the biodiesel is one of the method of utilizing nonconventional energy sources. Paper deals with the science of biodiesel technology. Process of biodiesel production is consists of several ch emical mechanisms. And the process of transesterification for different experiments and their final conclusion is taken for review. During the review of papers, experimental parameters like Engine performance parameters namely brake power, brake specific f uel consumption, brake thermal efficiency and exhaust emissions of CO, HC, NOx, and smoke density were analysed from studies carried out for different loading conditions and at constant engine speed of at different speeds. The test result indicates that th ere is an increase in brake thermal efficiency and slightly decrease in specific fuel consumption for all the blended fuels when compared to that of diesel fuel.
