Abstract
Animal fats are being explored for preparing bio fuel blends. In the present work pork fat oil is converted into bio diesel. B20 blend of this with the diesel is prepared and tested for its performance. The influence of injection pressure of the engine for handling this blend is investigated. The test conducted on a four-stroke single cylinder CI engine. Four types of injection pressures were used for running the engine. The brake thermal efficiency (BTE) shows improved values on increasing the injection pressure up to 220 bar, but at 240 bar the BTE values are not up to the mark. BSFC and NOx emission values are not showing much difference between the injection pressures. Hydrocarbon emissions were reduced on increasing injection pressures. Combustion parameters for this engine conditions are all of similar trend. Overall, it can be included that the B20 blend of pork fat biodiesel can be used in CI engine with slight increase in injection pressure for better performance.
