摘要： A fuel injection system (4) of an internal combustion engine of a vehicle such as motorcycle comprises a throttle body (6) of a cylindrical structure having a passage (6a) for supplying a fuel-air mixture to a combustion chamber of an engine, a disc-shaped throttle valve (8) disposed in the passage to be rotatable so as to regulate an amount of air flowing through the passage, and an injector means (10) mounted on a peripheral wall of the passage and adapted to inject fuel in the passage at a portion downstream side of the throttle valve (8) with respect to an air flow in the passage. The throttle valve is provided with a through hole (12) opened to both surface of the throttle valve, and the through hole being formed at a portion on an injector location side with respect to a rotational axis (8a) of the throttle valve so that an axis of the through hole substantially accords with a central axis (10a) of a fuel injection from the injector when observed from the injector location side.
