摘　　要：选取4款典型的非道路移动机械用小型点燃式发动机进行了PM测试,为后续排放控制政策制定提供数据参考,并提前为可能进行PM监管的美国/欧洲排放法规进行预研。结果表明二冲程通机PM排放远高于四冲程通机;从比排放数值上来看,二冲程通机PM排放几乎与我国四阶段非道路柴油机PM限值(P<37 kW功率段)在同一量级水平;四冲程通机PM排放还是远低于我国四阶段非道路柴油机PM限值(P<37 kW功率段)。In this paper,four typical small spark ignition engines for non-road mobile machinery are selected to test PM,which can provide data reference for subsequent emission control policy formulation,and pre study the U.S./European emission regulations that may be subject to PM regulation in advance.The results show that the PM emission of the two-stroke engine is much higher than that of the four stroke engine;the PM emission of the two-stroke engine is almost the same level as the fourth-stage emission limits for non-road diesel engine in China(P<37 kW);the PM emission of the four stroke engine is still far lower than the fourth-stage emission limits for non-road diesel engine in China(P<37 kW).
