- 摘要：
- A control method for modulating the torque in an internal combustion engine with mechanical power transmission and with pneumatically, hydraulically or electromagnetically controllable valves that are open and closed based on signals from a control system, by which method a torque that is requested in an operative situation at a certain moment is provided by a selection of the frequency with which power strokes are performed by controlling the number of power strokes in relation to the number of idle strokes. The power strokes take part in 2-stroke cycles or 4-stroke cycles, and one or more 2-stroke cycles are alternated with or more 4-stroke cycles.
