PURPOSE: To raise the durability of engine by restoring partial cylinder operation to full-cylinder operation when temperature difference in the operating and non-operating exhaust manifolds exceeds a fixed value. CONSTITUTION: During the partial cylinder operation period, the temperature at the thick portion of operating exhaust manifold is detected. When the difference between the output Va of the sensor and the temperature output Vb at the thick portion of non-operating exhaust manifold exceeds a fixed value, the output of the comparator 2 into which the voltage is put is switched, whereby the gate of the AND circuit 4 is closed, a reset signal is supplied to the flip-flop circuit 7, a signal is put in the relay 9 through the amplifier 8, a fuel injection signal is supplied to the injectors a4Wa6, and full-cylinder operation is started.
