とを特徴とするアイドルアツプ装置。 A bypass passage is connected in parallel to the intake passage before and after the throttle valve, and the amount of air passing through the bypass passage is controlled by an air control valve according to the pressure generated by the power steering, and fuel is increased by the amount of air passing through the bypass passage. In an idle up device that injects a large amount of water from an injection valve,
The air control valve includes a hydraulic valve body, a plunger that is slidably fitted into the hydraulic valve body and pivots according to the pressure generated by power steering, and a plurality of valves that communicate with each other through valve holes. an air-side valve body having a chamber; a flange portion that can abut a valve seat formed around the valve hole; and a valve member having a shaft portion that is loosely fitted into the valve hole and has one end abutting the plunger; It consists of a spring that is inserted between the valve member and the air-side valve body and presses the flange part in the direction of contacting the valve seat, and a small diameter part and a large diameter part are formed in the shaft part of the valve member in order toward the flange part. An idle up device characterized in that a tapered part is formed between a small diameter part and a large diameter part.
