| Abstract:The non-road national emissions control regulations and the status at home and abroad are briefly 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 components, 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. |
