A mathematical engine model which simulates the dynamic interaction of various engine components and processes is developed. The different components and processes included in the simulation are the air/fuel inlet element, the intake manifold, combustion, engine dynamics and exhaust emissions. The total simulation is developed generally so that it can be calibrated to analyze the performance of an arbitrary gasoline engine. The only required information for calibration is the engine's physical characteristics and some steady state engine data.
Application of the engine model to the analysis of a rapid transient demonstrates that the model is effective in generating expected engine behavior and exhaust emissions. The model is thus an extremely powerful tool in the design and development of engine control.
