Model-based combustion engine control method in which, in an energy balance model, the total energy input corresponding to the fuel air mixture is matched to heat output and converted heat energy

摘要

Method for controlling a combustion engine using an engine controller that includes a control unit with a dynamic structure that receives signals relating to engine state and load requirements. The control unit has a computer model that is matched to the engine type and simulates a high pressure process in which energy supplied by fuel air mixture is considered, a total combustion curve (QSB) determined and with the aid of it a heat output curve (QSH) determined according to a Vibe function, from which the pressure curve is determined.
