车用柴油机瞬变工况排放问题研究——瞬变工况排放测试与控制方法

A Study on Transient Emission in Vehicle Diesel Engine

本文介绍了车用柴油机瞬态工况排放问题由来,初步探讨了我国现阶段瞬态循环排放的研究方法。文章认为,随着排放法规愈来愈严格,瞬态排放要求必将提到议事日程,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。

The origin of vehicle diesel engine transient e-mission problem is introduced. A research method on current transient cycle emission is discussed. With the emission regulation more strict,transientemission demands must become the order of the day. Through the method of combining steady e-mission test with transient process simulation, we study transient emission performances. Some measures and results of control and decrease vehicle diesel engine transient emission are discussed in this paper.
