Claims (14)

A throttle chamber having an air chamber having one end connected to the air cleaner, a venturi chamber fixed to the other end of the air chamber, and a throttle valve connected to the venturi chamber opposite to the side to which the air chamber is joined; An injector disposed near a center of an air pipe through which air formed by the air chamber and the venturi chamber flows; An inlet opening upstream of the venturi chamber, an outlet opening in the venturi chamber, and a bypass passage formed between both chambers when the venturi chamber is joined to connect the inlet and the outlet; Disadvantages consisting of air flow meter installed in the middle of fuel injector. The bypass passage is located on a straight cross section with respect to the flow of air, and the disadvantages of the scope of claim 1 described in connection with the shape of the inner peripheral wall of the air pipe. The air pipe has a circular cross section at right angles to the flow of air, and the bypass passage has the disadvantages of the scope of claim 2, which is formed in an arc shape centered on the center of the air pipe. Disadvantages of claim 3, wherein the inlet of the bypass passage is arcuately opened on the circumferential wall surface of the air pipe. The inlet of claim 4, wherein the inlet is opened to face the air flowing through the air pipe. The injector is a dagger fuel injection device according to claim 1, which is sandwiched between an upper injector support formed on an upper support arm fixed to the air chamber and a lower injector support formed on a lower support arm fixed to the venturi chamber. . Disadvantages of claim 6 in which a fuel pipe for sending fuel to the injector is formed in the lower support arm. The injector is supported by being sandwiched between an upper injector support formed on an upper support arm fixed to the air chamber and a lower injector support formed on a lower support arm fixed to the venturi chamber, and the upper injector support supports the upper injector support of the bypass passage. Disadvantages of claim 1 in which the inlet opens through an inlet passage formed in the upper support arm. The inlet installed in the upper injector support portion has the disadvantage of claim 8 in the opening of the right angle to the air flowing through the air pipe fuel injection device. Disadvantageous fuel injection device of claim 9, wherein the upper injector support portion is provided with an annular wall portion implanted at right angles to the opening direction of the inlet. Disadvantages of claim 1, wherein the insulator is installed between the air chamber and the junction surface of the venturi chamber to prevent air leakage. Disadvantages of the scope of claim 1, wherein a throttle chamber having a throttle valve is attached to an end face of the venturi chamber opposite to the air chamber, through an insulator for preventing heat transfer. Disadvantages of claim 12, wherein the throttle chamber has grooves through which coolant is circulated. Disadvantages of claim 1 in which the air flow measurement circuit is attached to the outer wall of the venturi chamber. ※ Note: The disclosure is based on the initial application.
