Abstract

PURPOSE:To satisfy both the exhausting and driving performances by shifting from pausing cylinder group to operating cylinder group every time the whole cylinder operation is shifted to the partial cylinder operation without causing a bad driving feeling. CONSTITUTION:Outputs of the oxygen sensor 5-7 placed in the exhaust pipe 1b- 1d, in which three catalyzers 2-4 are provided, are fed as an air-fuel ratio compensating signal from the change circuit 16 to the fuel injection control circuit 11 through the air-fuel ratio control circuit 17. The said circuit 11 accepts outputs of the sensor for suction air quantity 9 and sensor for the number of rotation 10, and provides a corrected injection signal synchronized with the number of rotation to the injection valves 13 of cylinders #1-#3 and the ones 14 of cylinders #4-#6 through the control circuit for the number of cylinders 12. Also the said circuit 12 cuts off the fuel feed to the cylinders #1-#3 or the ones #4-#6 selectively in the range of less load, and changes the operated cylinders group to the other every time the whole cylinders operation is changed to the partial cylinders operation.
