Abstract: The number of working cylinders of the internal combustion engine is controlled so that the load of the internal combustion engine is relatively increased thereby to keep the combustion effect within an expected range. By controlling the number of working cylinders of the internal combustion engine also to other than integral numbers, the torque control of large freedom is continuously effected. Thus the torque characteristic is smoothed, thus improving the fuel efficiency and driveability at the same time.
