  • Method and apparatus for adjusting an internal combustion engine with variable valve timing
    Patent number: 6502545
    Abstract: A method for adjusting an internal combustion engine with variable valve timing wherein the current position of the accelerator pedal is associated with a set air mass and a set pressure. The set pressure is compared with a reference pressure and control of the set air mass takes place via the throttling device in the intake pipe when the pressure falls below the reference pressure, and control of the set air mass is carried out via the engine valves when the pressure exceeds the reference pressure.
