摘　　要：以非道路4R2U柴油机为例,首先进行原机性能参数调整,以及优化燃烧等技术参数调整,然后在SCR技术路线下,进行排放后处理试验研究。试验研究表明,在采用传统机械直列泵前提下,排放指标很难达到非道路欧ⅢB排放标准;若采用高压共轨系统,再采用SCR技术路线,理论上是可以达到非道路欧ⅢB排放标准的。Taking a non-road diesel engine 4R2 U as an example,first,the paper adjusted the original machine performance parameters,optimized the combustion technology and parameter adjustment. Then in the SCR technical route,it conducted the experimental research about after treatment. The experiments indicate that it is difficult for the engine with traditional mechanical in-line pump to achieve the Euro ⅢB emission standard. But in theory,it is possible for the engine with high pressure common rail system and SCR technology to achieve the Euro ⅢB emission standard.
