PURPOSE:To permit the smooth engagement of a clutch by a method wherein the valve opening time of a control valve immediately after the opening of a throttle valve is set to the valve opening time in the loop of the feedback control immediately before opening of the throttle valve and, thereafter, it is decreased gradually. CONSTITUTION:When the throttle valve 5 is opened for starting, the revolution number of the engine Ne is increased. In this case, the amount of auxiliary air, supplied to the engine 1, is not brought into zero even though the throttle valve 5 is opened, and the amount of the auxiliary air supplied in the feedback mode control loop immediately before opening of the throttle valve 5 is supplied continuously. Thereafter the amount of the auxiliary air is supplied to the engine 1 under decreasing by a constant amount at every inputs of the signals of a TDC. The amount of the auxiliary air is not decreased suddenly to zero even though the throttle valve 5 is opened and is supplied to the engine by decreasing it gradually after the opening of the throttle valve, therefore, the sudden decrease of the revolution number of the engine may be prevented and the smooth engagement of the clutch may be effected. |
