Device for controlling an internal combustion engine with a pre-compression

Device for controlling an internal combustion engine with a supercharging device through which a desired supercharging pressure is generated, comprising: a throttle control device that controls a throttle valve; a pressure sensor disposed in an intake pipe to detect an actual supercharging pressure; To be connected with the throttle control apparatus for selectively controlling a throttle opening of the throttle valve in response to an operation amount of an accelerator pedal, a control unit, which is designed; wherein the control unit comprises: (A) an arithmetic section that calculates a target air quantity that is used in an operating range of the engine with a lean air-fuel ratio based on at least the degree of depression of the accelerator pedal, (B) an arithmetic section which calculates the required boost pressure based on the engine speed and engine load, (C) an arithmetic section which calculates a boost pressure Korrekturtaktor which takes into account the operating range of the engine with a lean air-fuel ratio, a difference between the desired boost pressure and the actual boost pressure, and (D) an arithmetic section, of the target amount of air in the operating range of the engine with ...
