Abstract: From last ten year there has been number of increase in vehicles and corresponding to increase in the fuel price. For this reason the scientist will move towards alternative fuels like vegetable oils, biodiesel, etc. Biodiesel is one of the substitute fuels which is obtained from vegetable oils, Waste cooking oil. In this experiment, the biodiesel is produced from waste cooking oil using transisterification process, the present work has focused mainly on the performance and exhaust emission of waste cooking oil and its blend with diesel on diesel engine and its suitability is examined. The oil blended with diesel in proportion of 25/75%, 50/50%, 75/25%, and 100/100% on quantity basis after that biodiesel is analyzed. The performance and exhaust emission of blend are check out at a variable loads (brake power) of 0 1,2,3,4 at constant speed of 1500rpm and 5kW and results are compared. The experimental results show that there is mixing of lower percent of biodiesel in diesel give good results means increase mechanical efficiency, the brake thermal efficiency, and BSFC are well comparable with diesel. At full load CO, CO2, and HC are lower compare to diesel. Hence we can use the biodiesel which produced from waste cooking oil can be an alternative fuel in a diesel engine. And also up to B25 there is no modification of our engine.
