Abstract: Gasoline compression ignition (GCI) engines have received more and more attention owing to their high thermal efficiency and low harmful emissions. However, GCI engines fueled by pure gasoline with low reactivity are limited to poor combustion stability at low loads and high pressure rise rate at high loads. To this end, a kind of second-generation hydrogenated catalytic biodiesel (HCB) from waste cooking oil with high reactivity is blended into the China 95#gasoline with different volume ratios, and the effect of blended ratio on the combustion and emission characteristics of a heavy-duty diesel engine was explored in the present study. The results indicate that ignition performance is significantly improved as the increase in HCB proportion, maximum combustion pressure can be effectively suppressed, and the combustion stability under low load conditions is much enhanced. Furthermore, HCB blended ratio should match combustion phasing controlled by the start of injection (SOI) to obtain better engine performance and wider operation range. In terms of emissions, the gas emissions of nitrogen oxides, carbon monoxide, and unburned hydrocarbon can be significantly reduced with increasing HCB fraction, however, the particulate matter emissions are increased slightly as a penalty.
