| Abstract: | 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. |
