Abstract :
Heat release rate is one of the important factors affecting diesel engine characteristics. This paper presents a diesel engine dynamics model based on identification of heat release rate. Instantaneous engine speed and cylinder pressure can be obtained by numerical simulation of air intake and exhaust properties, in-cylinder combustion process and crank rotational dynamics by using the identification results. Simulation results of the engine speed and cylinder pressure well coincide with experimental ones for different external loads and nominal engine speed.
