INVESTIGATE OF DIESEL ENGINE WITH COMBINED PONGAMIA OIL AND JATROPHA

The present investigation, performance of Direct injection diesel engine has been tested with the combination of two oils namely jatropha and pong Amia, this two oils are been mixed with different percentages with this two oils and with diesel, Pong Amia 5%, Jatropha 5% and remaining diesel. The jatropha oil is only increased by 5% making pong Amia oil as constant, further combination are detailed discussed in the paper. Maximum percentage of jatropha oil was taken up to 25%. The performance test was conducted on twin cylinder stationary direct injection diesel engine coupled to swinging field dynamometer. The performance test consist of break power (BP), mass of fuel consumed (MFC), Brake Specific Fuel consumption (BSFC), Mechanical Efficiency, Break thermal Efficiency and Indicated thermal efficiency. From the results it was observed that the combination of two oils are showing better performance comparing with diesel. Out of the most pong Amia 5%, jatropha 15% was showing the best result.
