Engine Control Using Combustion Model

The combination of physical models of an advanced engine control system was proposed to obtain sophisticated combustion control in ultra-lean combustion engines, including homogeneous compression-ignition and activated radical combustion. Physical models of intake, combustion and engine thermodynamics were incorporated, in which the effects of residual gas from prior cycles on intake air mass and combustion were taken into consideration. The control of in-cylinder air/fuel ratio, misfire, knocking and auto-ignition was investigated using simulations.
