In view of the superiority of support vector machine and the fault characteristic of diesel engine, a classify method for diesel engine fault based on support vector machine is presented in this paper. First the cylinder block vibration signal on different condition was measured by the simulation test of diesel engine fuel injection system fault, then the feature parameter was extracted by empirical mode decomposition and the most impactful parameter was selected to be the input of support vector machine. The result shows that this method has fine classified ability and precision.
