成した燃料噴射装置。[Claims for Utility Model Registration] The throttle body to which the injector is attached is laterally assembled to the intake manifold, and the throttle valve is incorporated in the throttle bore passage leading to the intake manifold. This is a fuel injection device of the type that injects fuel from the throttle valve toward the throttle shaft of the throttle valve, and the throttle shaft injects fuel only on the downstream side when the throttle valve is closed. The fuel injected from the injector collides with the valve face of the throttle valve in the low opening range of the throttle valve, and hits the throttle shaft in the high opening range of the throttle valve. A fuel injector configured to collide.
