Summary:A method for a combustion motor that is initially used in a full Miller cycle or full Atkinson cycle that is advantageous with regard to efficiency. In full operation, a switchover to a partial operation takes place, wherein the intake valves associated with the combustion chambers that are to continue to be operated are switched over to actuation in accordance with a second valve lifting curve in order to achieve a switchover that is as torque-neutral as possible and is optimal with regard to efficiency. The closing time of the intake valve brought about by this second valve lifting curve is designed with respect to maximum volumetric efficiency.
