为保证我国风冷和水冷二冲程汽油机油达到国外先进质量水平，等效采用日本ＪＡＳＯ、美国ＮＭＭＡ以及ＡＳＴＭ有关试验方法，建立了二冲程油性能评定台架。该文介绍台架试验装置的组建情况，对试验方法、试验机的技术性能、所用的燃料和参比油也做了简要的说明 In order to ensure that the air-cooled and water-cooled two-stroke gasoline engine oil in China achieves the advanced foreign quality level, the two-stroke oil performance evaluation bench has been established by using JASO in Japan, NMMA in the United States and the related test methods of ASTM. This article describes the formation of bench test device, the test method, the technical performance of the test machine, the fuel used and the reference oil also made a brief description
