On the basis of mathematical simulation of the hydraulically intensified electronically controlled fuel injection system,the Genetic Algorithm (GA) was applied to the parameters’ optimum organization.The optimal process of GA was introduced,and some optimal results were obtained. According to the test condition,an optimal test result was compared with the initial result. The comparison shows that GA could guide the development of the system.
