Optimization Of Diesel Engine Running-in Indexes Based On Oil Analysis

With the development and perfection of tribological theory and a series of analysis instrument's invention, oil fluid analysis technic has been deeply enriched in theory and application. The application and development of computer make it possible to handle these abundant information which get from oil fluid using the technic. Oil fluid analysis technic acquires remarkable effect and obtains a lot of application in mechanical equipment's state monitoring such as engine, gear transmission, bearing system, hydraumatic system.The process of diesel engine running-in is a complex tribological system problem. We must analyze scientific how to make burnish rules and verify it through experiment. In this paper, we monitor diesel engine's burnish state using oil fluid analysis technology based on tribological theory, and also study and analyze the mechanism of worn-out, the features of microns produced during grinding in, diesel engine's burnish state and burnish trend. On these bases, we find out some methods how to Optimize the Burnish rules of diesel engine, and made it successful to take application of Orthogonal Test on the diesel engine running-in test.It proved by experiment that diesel engine's running-in's quality and time are affected by many factors such as machining quality of part's face, assembling quality of machine, burdening and speed, burnish oil etc. When setting down burnish rules, we must make these factors match up each other so that we can enhance burnish quality and shorten burnish time. On the precondition of not changing the manufacture technics, selecting and using a equal burnish oil and orthogonal test method's application on testing designs, fast running-in of diesel engine can be realized.In this paper, I also take a given diesel engine as a illustration to optimize it's running-in indexesed by application our study results. It was proved doable by optimized result.The study of this project can provide some method experience to the studying workon the aspect.
