摘要： A returning spring 7 of the electronic control throttle and a default spring 8 for securing an initial opening degree (default opening degree) of the throttle valve 3 have diameters different from each other, and both of the springs 7, 8 are held around a shaft of the throttle valve shaft 3 and arranged between a gear 43 attached to the throttle valve shaft 3 and a wall portion of the throttle body 100. A shaft supporting gap of the throttle valve shaft 3 is filled with an air leak preventing material, and a minimum opening degree on control purpose of the throttle valve is set to a value larger than an amount of overshoot of the throttle valve occurring when opening degree of the throttle valve is changed from a maximum opening degree on control purpose of the throttle valve to the minimum opening degree.

摘要： There is provided an air flow meter (7) for detecting the flow rate of air, an electronically controlled throttle (13) for opening and closing a throttle valve and a calculating device (14, 801) to which a target engine intake air flow rate, a value detected by the air flow meter, the position of a throttle valve detected by a throttle position sensor, and a value detected by an engine speed sensor are input. The calculating device calculates a time constant of a delay of response of the air flow rate into the engine, and an air flow rate passing through the throttle valve to compensate for the delay of response, and drives the throttle valve such that the flow rate of air passing through the throttle valve agrees with the calculated value.

摘要： To achieve an integration of components and the rationalization of the default opening mechanism of the throttle valve, a reduction of the load of the motor drive and a stabilization of the throttle control operation. In a default opening setting mechanism with which the default opening of the throttle valve 24 is maintained to be larger than the fully closed position when the electric current does not pass through the motor 12 driving the throttle shaft 18, the throttle lever 3 and the sleeve 45 are inserted and fixed, and the sleeve 42 united together with the return lever 2 is engaged with the sleeve 45 so as to be enabled to rotate in relative to the sleeve 45. The sleeve 42 is energized by the return coil in the close direction of the throttle valve 24 up to the initial opening position. This energized operation enables the return lever 2 to be coupled with the sleeve 3. A force for opening the valve for keeping the default opening the throttle valve 24 is energized by the spring 5 onto the throttle shaft 18 near the fully closed position.
