The development of fault diagnosis system for diesel engine based on fuzzy logic

The relationship between the condition of diesel engine and thermal parameters is too complicated to utilize threshold method to diagnose diesel engine´s fault. A method of fuzzy logic is used to develop a fault diagnosis system for diesel engine, with an aim to identify the diesel engine´s fault related to lack power of single cylinder. It is proven that this fault diagnosis system is capable of identifying automatically the diesel engine´s fault related to lack power of single cylinder, which is helpful to apply the thermal parameters to diagnose the diesel engine´s fault under ship environment.
