Biodiesel is known to be renewable fuel which shows less effect on the environment and it is a product obtained from various plant sources through trans-esterification. Many types of research are proposing for biodiesel/ biofuel as an alternative fuel without minimizing the efficiencies and reducing the effects of diesel on the environment and even without affecting the life of the engine and without modifying the engine hardware. In this experiment, we extracted biodiesel from raw canola oil by trans-esterification and fueled the engine by blending it with petroleum-based diesel. The results obtained were satisfactory. The properties of biodiesel like viscosity, fire point, flash point, density, calorific values are observed and they are found to be comparable with the petroleum-based diesel. In this study, we tried to show the results of both raw canola oil and canola biodiesel. By considering the efficiency of the engine the blends are compared. When blends are prepared with raw oil and fueled the engine B30 has shown some good results both in terms of emission and performance. It was observed that by using B30 there is 12% increase in efficiency, 8% decrease in fuel consumption, 32.5% reduction of HC, 30% reduction of CO2, 20% reduction in CO. In the case of canola biodiesel both the blends B40, B50 shown good results when compared to diesel both in performance and emission parameters. When B40 is used it was observed that a 40% reduction in Co, 30.5% reduction in Co2, 41% reduction in HC, 8% reduction in fuel consumption, 7% more in efficiency. When B50 is used 13.21% increase in efficiency, 9% reduction in fuel consumption, 22% reduction in the HC, 17% reduction in CO2, 7% reduction in CO.
