The existing evaluation methods of diesel engine technical conditions are introduced. The limitations of these methods and the advantages of support vector machines in handling small samples, nonlinearity and high dimension are analyzed. A model of technical condition assessment of diesel engine based on support vector machine is proposed. The characteristics that can characterize the change of technical condition of diesel engine are determined, and these characteristics are extracted through real vehicle test. The technical condition assessment model of diesel engine based on support vector machine is established and the diesel engine of some test vehicles is evaluated. The result proves that the application of support vector machine in the assessment of technical status of armored vehicle diesel engine is feasible.
