    摘要： A choke valve is controlled finely suited to the running state of an engine. A throttle valve (8) and a choke valve (9) are provided in series on an intake pipe (6), and the opening degree of the choke valve (9) is controlled by a stepping motor. The choke valve opening degree upon start of engine (start opening degree) is determined depending on the engine temperature. The stepping motor (11) is initialized at the fully closed side of the choke valve (9) when the power source for starting the engine is turned on. The start opening degree of the choke valve is judged to be closer to the fully closed side or fully opened side, and the stepping motor (11) is initialized at the fully closed side if judged to be close to the fully closed side, and at the fully opened side if at the fully opened side.

    摘要： A choke valve is controlled finely suited to the running state of an engine. A throttle valve (8) and a choke valve (9) are provided in series on an intake pipe (6), and the opening degree of the choke valve (9) is controlled by a stepping motor (11). A choke valve opening degree upon start of engine (start opening degree) and a driving pulse rate of a stepping motor (11) are determined depending on the engine temperature. When lower than the engine temperature TL, the pulse rate is set at first rate, or the lowest rate in a specified range. Depending on the engine temperature, the pulse rate is set higher gradually up to second rate TH. When releasing the choke gradually in warm-up operation, the pulse rate is lowered so as to obtain a choke opening degree of high precision by a high torque.
