ABSTRACT:
The invention relates to a method for operating a multicylinder internal combustion engine having a device, preferably an asymmetric swirl valve, located in the cylinder inlet passage and selectively movable by means of a control unit from a starting position into an effective position, for influencing the flow conditions in the cylinder inlet passage. In known methods the swirl control valve is brought into its effective position in a predetermined rotational speed/torque region and the engine is operated with a stoichiometric or rich mixture. Outside this region the swirl control valve is brought into its starting position and the engine is operated using a substantially stoichiometric or rich mixture. In contrast to this, a saving in fuel is obtained by bringing the swirl control valve into the starting position in a second predetermined rotational speed/torque region lying outside the predetermined first rotational speed/torque region and at the same time operating the internal combustion engine using a lean mixture.
