Claims

[Scope of utility model registration request]

An intake passage formed in the main body to supply air to the engine,
a venturi portion formed in the intake passage; a throttle valve provided in the intake passage downstream of the venturi portion; a bypass air passage connecting the venturi portion upstream of the venturi portion;
a hot wire sensor provided in the bypass air passage to detect the amount of air flowing through the bypass air passage; an air metering valve provided in the bypass air passage downstream of the hot wire sensor; and between the throttle valve and the venturi section. When the fuel passage that supplies fuel from the fuel pump to the opened fuel injection part, the fuel metering valve provided in the fuel passage, and the air metering valve are displaced in a direction to reduce the amount of air flowing through the bypass air passage, the fuel an electromagnetic device that drives the air metering valve and the fuel control valve to displace the metering valve in a direction in which fuel increases; and an electromagnetic device that drives the air metering valve and the fuel control valve, and compares the output of the hot wire sensor with a set level so that the output of the hot wire sensor remains approximately constant. In a fuel control device comprising a computer that provides a control signal to the electromagnetic device to control the air metering valve, the fuel metering valve, the air metering valve, and the electromagnetic device are assembled separately from the main body. Fuel control device.
