摘要
简要介绍了国内外非道路排放控制法规及现状。针对法规要求开发了新一代东方红LR4M3-24柴油机。通过采用新结构活塞、喷油泵、喷油器等零部件及运用内部EGR技术,使该型柴油机的排放指标全面达到《非道路移动机械用柴油机排气污染物排放限值及测量方法》(Ⅰ、Ⅱ阶段)中的Ⅱ阶段规定;且动力性、油耗、噪声、等性能均有所提高。
The non-road national emissions control regulations and the status at home and abroad are brief- ly introduced. To satisfy the emissions regulations, the new LR4M3-24 type Dongfanghong diesel engine was developed. Through the structure redesign of piston, injection pump and injector and some other com- ponents, and by inner EGR technology, the new type of engine satisfies the regulations of ＂Limits and Measurement Methods for Exhaust Pollutants from Diesel Engines of Non-road Mobile Machinery （II） ＂, and its power, fuel consumption, noise and some other performance parameters are improved also.
