Abstract

PURPOSE:To keep good exhaust cleaning action all the time by stipping the control of the cylinder number under low-temperature condition that oxygen sensor does not operate properly. CONSTITUTION:When the revolution number of engine and the pulse width of fuel injection are in the 6-cylinder zone, the output level of the VCS circuit 16 is 1 and the cylinders #1 to #3 are put into operational state. Then, the output of the oxygen sensor 10 is put in the air-fuel ratio control circuit 12. When the engine becomes a light-load state and the pulse width and the engine revolution number sift to the 3-cylinder zone, the cylinders #1 to #3 come into stopped state. Thus, the selective relay 11 is switched to the oxygen sensor 8 side and the ternary catalyst 7 on the working cylinder groups #4 to #6 exhibits a high conversion efficiency. When the catalyst 9 and the oxygen sensor 10 are cooled to a low temperature at which their proper outputs can not be exhibited, whole cylinder operation is restored forcibly by the output of the low temperature detector.
