項に記載の内燃機関の空燃比制御装置。[Scope of Claim for Utility Model Registration] 1. A mixture regulating valve is provided which is operated by negative pressure in the intake passage in order to supply secondary air to the intake passage when the carburetor throttle valve is suddenly opened;
An air-fuel ratio control device for an internal combustion engine, comprising a control device that controls to stop supply of secondary air to the intake passage under predetermined engine operating conditions. 2. The secondary air control device includes a valve in the negative pressure passage that introduces negative pressure in the intake passage to the air-fuel mixture adjustment valve that closes when the starter is operating and under any conditions of below a predetermined engine speed and below a predetermined vehicle speed. An air-fuel ratio control device for an internal combustion engine according to claim 1, which is a control device with an intervening mechanism. 3. The secondary air control device controls the secondary air passage that starts at the air-fuel mixture adjustment valve and supplies secondary air to the intake passage under any of the following conditions: during starter operation, below a predetermined engine speed, and below a predetermined vehicle speed. The air-fuel ratio control device for an internal combustion engine according to claim 1, which is a control device that includes a valve mechanism that closes even when the engine is closed. 4. The secondary air control device has an opening end in the intake road of a negative pressure passage that introduces negative pressure in the intake passage into the air-fuel mixture adjustment valve downstream of a valve end of a downstream valve portion of the throttle valve in the closed state. Claim 1 for utility model registration characterized by a control device
The air-fuel ratio control device for an internal combustion engine according to item 1.
