摘　　要：根据ISO EGD规范中要求的CEC L-079-T-97清净性评定标准方法,采用其规定的动力设备以及自行设计配套的测控设备,建立了EGD级二冲程油清净性评价系统。经校机试验证明:不同质量的油品,清净性指数有较大差异,具有良好的区分性;相同油品多次试验数据接近,重复性高;所得试验数据证明与国际领先水平的EGD评定技术与装备功能等效。According to CEC L-079-T-97 detergency evaluating method for two-stroke gasoline engine oil （2T oil） which was regulated by ISO EGD standard, a detergency evaluating system of EGD 2T oil was set up. Both the standard engine and self-designed control system were used in this system. Checking test results indicate that the evaluating system has well distinguishability since detergency indexes for different quality grades＇ oils have great distinction, and it also has high repeatability for test results because the repeat test results of the same oil samples are very adjacent. It is proven that this evaluating system of EGD 2T oil is equivalent with the foreign ones in the international leading level.
