PERFORMANCE INVESTIGATION ON VCR ENGINE BY USING BLENDED COCONUT OIL

Energy is a key factor for the development of any country. With the increased civilization and industrialization the need for energy is increasing day by day. Majority of the world’s energy demand is met through fossil fuels and natural gas. As a result fossil fuels are diminishing from year to year. Since fossil fuels are no renewable, fuel price is increasing with spiraling Demand and diminishing supply. To avoid dependency on foreign countries the use of renewable energy has become important. The coconut is considered as natural asset in India Thailand and some other countries on the globe.   So our Endeavour is to use coconut oil as alternative to conventional fossil fuels. Decrease in indicated thermal efficiency with similar values of brake thermal efficiency and volumetric efficiency is observed compared to diesel. In view of emission parameters a significant improvement is achieved. The use of coconut biodiesel as fuel for diesel engine will reduce dependency on fossil fuels and decrease environmental pollution.
