摘要：
An experimental study has been conducted to reveal combustion and emission characteristics of biodiesel-fuel engine equipped with EGR. The effect of ambient temperature and oxygen concentration on ignition delay time at self-ignition combustion of biodiesel was measured by using a constant volume combustion chamber. Engine bench test results show that low smoke emission achieved by using biodiesel and high pressure injection enables high EGR ratio, which results in lower NOx emission compared to gas oil. Also, it is indicated that a large amount of EGR combined with high-pressure injection is effective to reduce SOF content in PM emission from biodiesel.
