摘　　要：通过对美国船舶制造商协会(NMMA)TC-W3清净性评定技术和评定设备进行研究,提出了TC-W3高档水冷二冲程油清净性的简易评定技术.采用Piaggio180单缸、水冷二冲程发动机建立了TC-W3二冲程油的简易清净性评定试验台架,制定了相应的试验方法.利用舷外机的250 h系泊试验和OMC J70HP试验对笔者所建立的高档水冷TC-W3油简易评定技术进行了试验验证.结果表明,TC-W3简易清净性评定台架分辨效果明显,试验结果趋势一致.通过各种油样进行简易清净性试验,制定了清净性简易评定指标.Based on the evaluating techniques and equipments of national marine manufacturer association（NMMA） TC-W3 oils, the simple evaluating techniques for detergency of high-grade water-cooled two-stroke-cycle oils were put forward in this paper. The test bench, adopting single cylinder, water-cooled, Piaggio 180 engine, was established to evaluate the detergency of TC-W3 oils. The simple detergency test procedure for evaluating TC-W3 oils was also established. The detergency test bench was validated by 250 h mooting trial test of outboard engine and OMC J70HP test. Test results indicate that the detergency test bench can distinguish different oils obviously, and test dada are consistent and reliable. By testing a set of oil samples on the detergency test bench, the pass index was set up .
