Abstract

The effects of different EGR rates and injection timings on lowtemperature combustion of biodiesel engine were simulated and analyzed by GTPower. The results show that the combustion phase moves backward, the maximum combustion pressure, the thermal efficiency and the NO_x emission decrease and the highest average incylinder combustion temperature, the brake specific fuel consumption and the soot, CO and THC emissions increase with the increase of EGR rate. With the delaying of injection timing at the same EGR rate, the combustion phase still moves backward, the maximum combustion pressure, the average incylinder combustion temperature and the NO_xemission decrease, the CO and THC emissions increase, the brake specific fuel consumption first decrease and then increase and the thermal efficiency and soot emission first increase and then decrease. In addition, adjusting the EGR rate and injection timing can reduce both NO_x and soot emissions, but will result in a significant deterioration in fuel consumption and thermal efficiency as well as CO and THC emissions.
