The Performance Evaluation and Emission Study of Compression Ignition Engine Operating with Blends of Animal Fat and Palm Oil Based Biodiesels

Depletion of origin and anguish of health issues due to emissions by petroleum discharge triggered to take necessary steps to avoid adverse effects on forthcoming generation. In view of this tremendous work is being done to diminish dependence on fossil fuels by biodiesel which are ecofriendly. In this research work an investigation of biodiesel blends with diesel at different ratios will be done. Blends of pig fat biodiesel and palm biodiesel are prepared with different proportions of diesel. The composition abbreviated as APD with prefixing different percentage which indicates the quantity of biodiesel. From results recorded, it has noticed that 20% APD can be directly used without any modification in the engine. Performance results and emission results are acceptable for 20% blend which is in range with diesel. HC and CO emissions are less for all blends but CO2 and NOx emissions increases with blend ratios. 20% APD sample emission data is well compromised with diesel at all loads. Hence it can be said that 20% APD can be a potential sample that can be used directly in engine without modification.
