摘　　要：介绍了车用柴油机瞬态工况排放问题的由来 ,初步探讨了我国现阶段瞬态循环排放的研究方法。随着排放法规日益严格 ,瞬态排放要求已提到议事日程 ,限于我国现阶段瞬态循环排放测试实施有困难 ,通过稳态排放试验和瞬态工作过程模拟相结合的方法来研究瞬态排放性能 ,在一定程度上可弥补直接进行瞬态测试的困难。文中还讨论了控制和降低车用柴油机瞬态工况排放的一些措施及其效果。This paper described the origin of the transient exhaust emissions of vehicle diesel engine, and discussed the methods for the research of exhaust emissions under the transient test procedure in our country. It is thought in this paper that the transient exhaust emissions will be put forward to solving because of more and more stringent exhaust emission legislations. Regarding to the difficulties of the transient exhaust emission test in our country nowadays, the method, steady state exhaust emission test combined with transient process simulation, can make up for the difficulties of the transient exhaust emission test to some extend. Some measures to reduce and control the transient exhaust emission of vehicle diesel engines and the results were also introduced.
