摘　　要：目前国内已经开始执行《非道路移动机械用小型点燃式发动机排气污染物排放限值与测量方法(中国第一、二阶段)(GB 26133-2010)》的第二阶段限值。为了考核发动机的排放劣化情况,二阶段排放需进行耐久测试。国标中没有过多的耐久试验方法。通过分析美标和欧标中的有关耐久规定,推荐选择一种通用小型汽油机耐久测试方式。According to requirements in GB 26133-2010 Limits and measurement methods for exhaust pollutants from small spark ignition engines of non-road mobile machinery（I,II）,phase 2 standard has been effective. To evaluate deterioration tendency of exhaust emission from engine,durability test is applied in phase 2 standard. Description on mode of durability test is limited in this GB standard,so related requirements in American standard and European standard are referred and analyzed to select one durability testing mode for general small gasoline engine.
