The Study of Wear Evaluation in Reliability Test of Diesel Engine Based on Oil Analysis
基于油液分析的柴油机可靠性试验磨损评价研究

The 1 000 h reliability test of an EQD diesel engine was investigated.The concept of in site wear evaluation was used in the reliability test of diesel engine and the wear evaluation was designed as one method of identifying the reliability of diesel engine.On the wear evaluation,the oil analysis approaches such as oil spectrum analysis,ferrography and PQ analysis,with trend graph analysis,were adopted to describe the wear condition of every stage of test.The oil analysis results showed that the test engine...
