摘要： A method for improving the torque band of a multi-cylinder, four-cycle piston internal combustion engine comprising at least two cylinder pairs including variably triggered gas exchange valves, wherein each cylinder pair comprises two cylinders associated with each other by a firing interval of 360° crank angle, and wherein one cylinder pair is not fired by cutting off the fuel supply and acting upon the gas exchange valves resulting in a partial load operation. The method includes triggering the cylinders of the non-fired cylinder pair during the partial load operation so that such cylinders take in a predetermined charge quantity for adjusting a predetermined compression level that influences the torque band. The gas exchange valves of the non-fired cylinders are maintained closed for the duration of the partial-load operation and the associated gas intake valve and/or gas discharge valve is opened only briefly solely to influence the charge quantity during the piston passage through bottom dead center.
