Abstract
PURPOSE:To secure smooth acceleration by preventing the mixture, to be fed in the engine cylinder from becoming temporarily too thin at the moment when the throttle valve is opened. CONSTITUTION:The carburetor 3 consists of the primary side carburetor A and the secondary side carburetor B, and the air bleed 22 is connected to the inside of the main fuel passage 16 of the primary carburetor A, and the air bleed duct 29 is connected to the slow fuel passage 24, and it is also connected to the electro-magntic control valve 23. The secondary carburetor is also connected to the electro-magnetic control valve 23 through air bleed ducts 39 and 44. The electro- magnetic control valve 23 is controlled by the concn. of the oxygen in the exhaust gas. The flow control main reed valves 80 and 82 of the first and second main air bleed passage 22 and 39 are engaged with the first connection part, and the flow control slow reed valves 79 and 81 of the first and second slow air bleed passage 29 and 44 are engaged with the second connection part, and the main reed valves 80 and 82 are opened after the slow reed valves 79 and 81 are opened.
