【摘要】：采用SRV摩擦磨损试验机、HFRR高频往复试验仪对GF-50W-20、A5/B50W-30汽油机油加入有机钼型和胺类有机化合物摩擦改进剂后在不同试验条件下的摩擦磨损性能进行考察;通过发动机扭矩试验进一步验证加入摩擦改进剂后汽油机油在发动机上的实际扭矩变化,确定摩擦改进剂对汽油机油摩擦性能的改善效果。结果表明:采用SRV摩擦磨损试验机、HFRR高频往复试验仪能够区分不同摩擦改进剂的性能差异;摩擦改进剂的适量加入可以降低汽油机油摩擦试验的摩擦因数,降低发动机的摩擦磨损和扭矩,改善汽油机油的燃油经济性。SRV及HFRR模拟试验结果与发动机扭矩试验结果具有较好的一致性。
[Abstract]:By using SRV friction and wear tester, HFRR high frequency reciprocating tester of GF-50W-20 A5/B50W-30 gasoline engine oil with organic molybdenum and organic amine compounds after the friction and wear properties of friction modifier under different experimental conditions were studied; the engine torque test validate the actual torque change of gasoline engine oil in the engine with friction modifier, identify improvement the effect of friction modifier on the friction performance of gasoline engine oil. The results show that the SRV wear test machine of the difference of HFRR high frequency reciprocating tester can distinguish different friction modifier; friction modifier added friction factor can reduce the friction test of gasoline engine, reduce engine wear and friction torque, improve the fuel economy of gasoline engine oil.SRV and HFRR simulation has good consistency with the engine torque test results the test results.
