摘　　要：中重型车用柴油机排放已成为降低车辆排放的主要控制目标。本文论述我国中重型车用柴油机满足欧 Ⅱ排放所需采取的技术措施。讨论了采用增压中冷、提高喷射压力、控制供油速率,优化喷油定时、改进燃烧系统、控制机油耗及燃油质量、降低燃油中含硫成分等关键因素对排放的影响程度。The exhaust emission of diesel engines for HD & MD vehicle has become the main controlled aim of reducing vehicle emissions. This paper introduces the technical measurements adopted for meeting EuroⅡexhaust emissions regulation. The effects of the key factors, such as supercharging with intercooler, injection pressure, fuel delivery rate, fuel injection timing, combustion system, oil consumption as well as the quality of the fuel, on the exhaust emissions have been discussed.
