【Abstract】 A zero-dimensional model for a naturally aspirated diesel engine has been established in this paper. The stable performance and dynamic characteristics of the diesel engine has been simulated and tested. The tolerance of modeling is less than 2%. The dynamic model has been simplified from the point of view of desiring of controller design. The simplified model has the nonlinear characteristics of the diesel engine and its accuracy of dynamic process modeling has reached to 95%.更多还原
