１項所載のエンジンにおける混合気の制御装置。[Claims for Utility Model Registration] 1. A main intake passage 1 that guides a relatively lean air-fuel mixture into the main combustion chamber of an engine, and a sub-intake passage 2 that leads a relatively rich air-fuel mixture to a sub-combustion chamber of the engine. These passages are arranged in parallel 1.2
A type having a main throttle valve 3 and a sub-throttle valve 4 on the upstream side of the main intake passage 1, and a choke valve 5 that closes at low temperatures on the upstream side of the main intake passage 1, - the sub-throttle valve 4 in the sub-intake passage 2; A control device for an air-fuel mixture in an engine, comprising a secondary air passage 6 which is connected to the outside air on the downstream side thereof, and a thermo valve or other temperature-responsive valve 7, which opens when the engine is low, is interposed therein. 2. The air-fuel mixture control device for an engine as set forth in claim 1 of the Utility Model Registration Claim, in which a control valve 8 that is closed during cranking of the engine is interposed in the secondary air passage 6.
