摘要
针对国内小型通用汽油机工业的发展状况,以美国和欧盟的小型通用汽油机第二阶段排放法规为依据,对188F小型通用汽油机进行试验研究;从生产控制出发,用五气分析仪检测汽油机尾气排放物的浓度,给出测量值与整机排放值的关系。试验给出了小型通用汽油机达到美国和欧盟第二阶段排放限值和能优化汽油机综合性能的方法和措施。
This paper introduces the development of domestic non-road spark-ignition small engines. Aiming at the American and European requirements on the emission limits, we carry out experiments on 188F engine and detect its emission density with the five-gas analysis apparatus. And bring forward some effective measures to reach the foreign present emission limits and optimize the small gasoline engines.
