摘　　要：节能减排已成为当今社会发展的一大主题,通用小型汽油机作为一种常见的动力装置,其排放已逐渐成为大气的主要污染源之一。针对通用小型汽油机的排放现状,分析了过量空气系数、点火系统、转速、负荷、调速器的稳定性、废气再循环技术、催化转化技术和燃料等对排放的影响,相应地提出了降低尾气排放的技术路线,有助于通用小型汽油机节能减排路线的优化。Energy conservation and emissions reduction have become a major theme in today＇s social development. Non-road small spark-ignition engine is a type of common power units, its emission has gradually become one of the main atmospheric pollution sources. Aiming at the current situation from the emission of non -road small spark-ignition engine, we mainly analyze the effect of excess air coefficient, ignition system, speed, load, the stability of governor, EGR, catalytic conversion technology and fuel on the emission, and put forwards technical routes to reduce exhaust emission. That＇s helpful for optimization of energy conservation and emission reduction routes for non-road small spark-ignition engine.
