BIODIESEL AS A BLENDED FUEL IN COMPRESSION IGNITION ENGINES

K A. Sorate

Abstract: Fast depletion of fossil fuels, rapid increase in the prices of petroleum products and harmful exhaust emissions from the engine jointly created renewed interest among researchers to find the suitable alternative fuels. The literature survey shows that the yield of Hibiscus Cannabinus seeds per hectare is about 800 kg and oil yield is about 120 liter (15-18 % yield). Its by products are fiber and cake, find wide spread applications. It is found that physical and chemical properties of Hibiscus Cannabinus oil biodiesel are very close to the diesel. The authors have conducted experimental tests on a single cylinder diesel engine using Hibiscus Cannabinus oil biodiesel and diesel blended fuel. The performance parameters like thermal efficiency, brake specific fuel consumption, fuel – air ratio and smoke tests are determined through experimentation. The authors concluded that the Hibiscus Cannabinus oil biodiesel biodiesel could be used as an alternative fuel in the blending form.
