ング運転制御装置。[Claim for Utility Model Registration] A distributor in an internal combustion engine is connected via a negative pressure passage to a negative pressure port downstream of a throttle valve in a carburetor, and when the negative pressure in the negative pressure port is large,
While providing a sub-negative pressure advance mechanism to advance the ignition timing,
The throttle valve in the carburetor is connected to a negative pressure port downstream of the throttle valve in the carburetor via a negative pressure passage, and when a large negative pressure acts on the negative pressure port, the throttle valve is in a closed position. A dashpot is provided that moves the closed position of the throttle valve in the closing direction and in the opening direction when no negative pressure is applied, and a negative pressure passage connecting the dashpot and the negative pressure port is provided with a A switching valve is provided to cut off communication between the negative pressure port and the dashpot when the electrical load is turned on, and at the same time open the dashpot to atmospheric pressure. A temperature sensing valve that is open to atmospheric pressure is connected, and a negative pressure passage that connects the dashpot and the negative pressure port is provided with a valve that opens toward the dashpot between the switching valve and the dashpot. An idling operation control device for an internal combustion engine, which comprises a check valve and an orifice arranged in parallel.
