置。 The slow system and main system are configured to maintain an appropriate air-fuel ratio by controlling the fuel flow rate to maintain a constant liquid level in the negative pressure passage that communicates with the fuel passage, and the fuel passage is shared. The fuel flow rate of both systems is controlled by a solenoid valve disposed in the middle of the air valve, and the air valve that can block the intake passage in the slow region is connected to a negative pressure actuator operated by negative pressure downstream of the air valve. In the fuel supply device configured to further control the operating negative pressure of the negative pressure actuator by a control valve, a connection between the negative pressure chamber of the negative pressure actuator and the control valve is connected to the atmosphere through a restriction. An air-fuel mixture supply device characterized in that the air-fuel mixture supply device is connected to each other so that the amount of atmospheric air leaked through the throttle can be changed depending on the warm-up state of the engine.
