Abstract:
Considering the differences between diesel and biodiesel fuels, engine condition should be modified based on the fuel or fuel blends to achieve optimum performance. In thisstudy, the effect of fuel injection timing on performance of a diesel engine was investigated experimentally using environmental friendly diesel-biodiesel blends. Different experimentswere carried out on the test diesel engine at engine speeds of 1200, 1600, 2000 and 2400 rpm.The injection timing was regulated for 10, 15 and 20 degree crank angle BTDC. The experimental results related to engine torque, BSFC, cylinder pressure and exhaust gastemperature for fuel blends of B20, B40, and B100 at different engine speeds and injectiontimings were recorded and analyzed. The results showed that advancing the fuel injectiontiming for fuel blends of B20, B40, and B100 increased engine torque approximately 2.1%,2.9% and 6.3% respectively and decreased maximum brake specific fuel consumption approximately 2.7%, 3.3% and 6.6% respectively
