ABSTRACT:
A throttle body adapted to be mounted between an intake pipe and an intake manifold, the throttle body comprising an upstream body connected to the intake pipe and formed with a substantially horizontal suction passage; a downstream body connected to the intake manifold and formed with a downwardly inclined throttle bore, the throttle bore continuously extending from the suction passage on a downstream side thereof; a throttle valve rotatably mounted in the throttle bore of the downstream body; and a fuel injector mounted to the upstream body in such a manner as to inject fuel toward the throttle valve; wherein the fuel injected from the fuel injector collides with the throttle valve to be atomized and distributed in the downstream body, and is supplied to the intake manifold.
