Diesel Fuel Supply System Faults Diagnosis Based On Fuzzy Pattern Recognition

In modern society with larger number of automobiles, the questions such as severity of the exhaust emission and traffic accident emerges. Meanwhile, bring the greater maintain work. The engine is the drive force of the car, and more and more use of the diesel engine in it, the work state is crucial for the car. It is important to diagnose the fault of the diesel engine for solve "the car question".The fuel supply system is the heart of the diesel engine, which is made up of the fuel injection pump, high pressure oil tube and injection implement. Its condition effects the combustion course directly and decides the performance of the engine. So it is vital to do the check and diagnosis for the supply system. The paper gives a detail introduction for the compose and work course, typical faults.A plenty status messages are in the pressure wave of the high pressure oil tube, the signal is the important characteristic which reflect the work condition of the supply system. The faults of the system comes up, and the reflection is on...
