Repair Of Locomotive Diesel Engine Performance Testing And Diagnostic Techniques

In order to guarantee the locomotive's dynamic behavior, economy and the reliability, we must keep the diesel engine running in the good situation. Because the diesel engine is the most important component of the locomotive. It can affect the locomotive heavily. Before the diesel engine is fixed, it will be tested to keep the correctness of the parameters. The spot equipment and instruments are very lag, and it will depend on the works' experience to evaluate the status of the objects. In order to solve these problems, on the base of analyzing the related datum, according to the special instance of China, the writer study and explore a system which is constituted by the Pc computer and the single chip microprocessor. This system has some characteristics: in the part of the hard ware we use the personal computer as the core processing unit and in the part of the soft ware, this system is based on the Windows operating system and is compiled by use of the popular computer language-Visual Basic, C and assemble language.. Otherwise it uses the fuzzy theory to help judging the status of the diesel engine and uses the engine power, fuel consumption rate, temperature of the exhaustion and the speed of the diesel or the supercharge air pressure and other parameters to evaluate it's integer performance. When choosing the hard and soft ware, we think over the experiment environment of the diesel engine sufficiently then adopt a series of effective measures to promise the precision and veracity and the ability to anti-jamming. Through managing in the sports, this system can finish the goal basically and accord with the requests. It has biggish utility value.
