TC-W3高档水冷二冲程汽油机油润滑性评定技术的研究

水冷二冲程汽油机油主要应用于水上作业的舷外机（摩托艇）等动力机械，高档的水冷二冲程汽油机油既要具有环境友好的清净性，又要具备优秀的润滑性，才能保证其可靠性。结合国际上的有关标准，建立了与NMMA等效的TGW3水冷二冲程汽油机润滑油发动机台架评定装置，进行了高档水冷汽油机油（TC—W3级）的润滑性评定试验。结果表明，该润滑性评定装置运行稳定，具有良好的区分性，试验手段科学，试验数据准确可靠。

STUDY ON EVALUATING TECHNIQUES FOR LUBRICITY OF TC-W3 GRADE OIL USED IN TWO-STROKE WATER-COOLED GASOLINE ENGINES

Water-cooled two-stroke gasoline engine oils were mainly used in outboard marines(also called motorboat).The high-grade oils are required to have not only better detergency for friendly environment,but also the excellent lubricating quality to ensure their reliability.Here were introduced the evaluating techniques and a set of equipment developed by authors according to the advanced technology and standards in the world.Some experiments on water-cooled two-stroke gasoline engine oils(TC-W3 grade)were carried out.The results showed that the set of equipment run stably with the feature of good scientific in test method, data reliability and distinguishable capability.
