Abstract

In the range where the fuel efficiency may be improved by relatively increasing the load of working cylinders at the time of partial loading of a multicylinder internal combustion engine, the intake pressure of the engine is maintained at a fixed optimum value. Also, the number of working cylinders is controlled, so that a torque actually required by the driver is obtained, and under any load, the maximum improvement of fuel efficiency may be attained at a saving of fuel consumption.
