| Abstract: | In order to judge the faults in gas exchanging system of marine diesel engine rapidly and exactly, based on the operational process of the gas exchanging system of marine diesel engine, an effective fault diagnosis method is proposed in which there are 7 fault indication types, 19 fault date types according to the fault states of the gas exchanging system of marine diesel engine. A membership function about the fault indication is set up, the fuzzy fault diagnosis is applied into the gas exchanging system of marine diesel engine, and the fault diagnosis is performed according to the principle of the maximum degree of membership. |
