COMPARISON OF PERFORMANCE AND EMISSION CHARACTERISTICS OF MAHUA AND JATROPHA METHYL ESTER WITH BIOADDITIVE IN VCR ENGINE

The search for alternative fuels in last few decades is intensive due to the rapid depletion of petroleum fuels and their ever increasing costs. There is a great need to reduce the consumption of conventional fuels in both developed and developing countries. The consumption and demand of the petroleum based fuels is increasing every year due to the increased industrialization and innovation in the world. The aim of the present experimental work is to evaluate the impact of various compression ratio using blends of diesel fuel with 20% concentration of Methyl Ester of Jatropha biodiesel blended with bio additive and the blends of diesel fuel with 20% concentration of methyl ester of mahua biodiesel blended with bio additive as an alternate fuel. The experiment is carried out with three different compression ratios in DI diesel engine. Biodiesel is extracted from Jatropha oil and mahua oil, 20% (B20) concentration with 3ml bio additive is found to be the best blend ratio from the earlier experimental study. 3ml of biodiesel B20MEOJBA and 3ml of B20MEOMBA is tested with compression ratio of 17.5. The purpose of the experimental study is to obtain better efficiency, minimum specific fuel consumption, and lower smoke and lesser emission. This is done by increasing cetane number using combustion additives of 3ml bio additive blends with biodiesel when compared with the baseline diesel.
