Abstract

In a method for controlling an internal combustion engine comprising an intake pipe and a throttle valve that is arranged therein, the pressure in the intake pipe is regulated by modifying the opening angle of the throttle valve, and the desired pressure value is adjusted when the valve lift of the internal combustion engine changes. An apparatus for controlling an internal combustion engine has a mechanism for regulating the intake pipe pressure, the mechanism allowing the opening angle of the throttle valve to be influenced as a controlled variable. In addition, at least one device is provided for changing the valve lift of the internal combustion engine while a device is provided for adjusting the desired pressure value to the valve lift.
