非道路柴油发动机台架循环排放试验方法研究

The Research of Emission Test Method of Non-road Diesel Engine on Bench

本文介绍了我国非道路移动机械柴油机污染物排放法规的发展现状与过程。并结合非道路柴油发动机国四排放升级主要技术路线,着重对非道路国四柴油发动机瞬态循环、稳态循环、非标准循环测试规范及结果有效性判定方法进行研究和介绍。

The current situation and the development process of pollutant emission regulations is introduced about non-road mobile machinery diesel engine at China in this paper.Combined with the main technical route of non-road diesel engine National IV emission upgrade,it is focused on non-road transient cycle,non-road steady cycle,non-standard cycle of the test specifications and the result validity judgment methods for non-road diesel engine is introduced and researched.
