Unascertained Measure Model on Fault Diagnosis of Diesel Engine Turbocharging System

By way of analyzing uncertainty on the classification of state parameters of Diesel Engine turbocharging system, this paper defines index distinguishable weight on basis of classification and builds the unascertained measure model of the comprehensive evaluation on fault diagnosis of Diesel Engine turbocharging system. Then it explains diagnostic procedure and usage on index distinguished weight by means of a example. This model is applied to fault diagnosis of Diesel Engine whose state parameters possessing criteria for partition of the fault grade.
