摘　　要：本文提出了基于可能性测度的柴油机故障诊断方法.与概率测度相比,可能性测度更为适合,计算更为简单,在故障诊断中有着广泛的适用性。Possibility measure of fuzzy integrals of fault diagnosis was obtained by extending the probability measure from probability space to fuzzy sets.A new method of fault diagnosis for the diesel engine based on the possibility measure is developed in this paper.Comparing the two methods the definition and computation of the possibility measure seem to be more reasonable and simpler.This new method may be applied in engineering because the confidence of fault diagnosis for the diesel engine is expressed in fuzzy words.

关 键 词：柴油机 故障诊断 可能性测度
