| Abstract: | The protable fault diagnosis system was designed according to the features of the diesel engine with P-T fuel system. The problem, that is, the high pressure pulse sensor signal cannot be obtained because there is not the high-pressure line, was solved through the non contact orientation signal. The engine faults can be diagnosed according to the comparison of these measured parameters of the engine with the technical requirements provided by the engine manufacturers. Therefore, the evidences of maintenance and management can be gained for the diesel engines. The practical application shows that the measurement system, especially with respect to the method for measuring gas leakage from cylinder by starting electrical current, is very convenient and effective. |
