Abstract
PURPOSE: To improve fuel consumption at deceleration by opening a control valve connected to an air feed pipe which opens into a suction port downstream a throttle valve, at a running a period where a suction negative pressure is great, thereby allowing a great quantity of air into the suction port.
CONSTITUTION: Is installed an air feed pipe 50 which bypasses a venturi 58 and a throttle valve 45 within a carburetor 41 to connect an air cleaner 51 with a suction manifold 47. On the side of the air cleaner 51 of the pipe 50, there form an air nozzle 25 equipped with a valve body 18 opened or closed by a diaphragm 16, and an auxiliary air pipe 29. On the side of the manifold 47 a low speed nozzle 53 which is communicated with a low speed fuel passage 55 opens to the manifold. When the throttle valve 45 is completely closed with the engine at idling, a mixture for the idling is supplied from the auxiliary air pipe 29 and the low speed nozzle 53, respectively. When the engine is decelerated and the suction negative pressure grows, the valve body 18 is opened to allow a great quantity of air to be carried from the air nozzle 25 into a suction system.
