Abstract
In a fuel injection apparatus of an internal combustion engine comprising a fuel injector, an intake valve device for opening and closing an intake port, and an intake air flow control device arranged in an upstream side of the intake valve device, a fuel injection is synchronized with an intake stroke of the engine. A fuel spray is oriented to an inner wall face which is positioned in an opposite side to an inner wall face of a cylinder heads in a fuel injector side and the fuel spray is transported by an air flow having a strong fluidization which is entered from the intake air control device. In a port injection lean burn engine, an adhesion to the wall face according to the fuel spray can be reduced, and a quality and a formation state of an air-fuel mixture in a cylinder can be improved.
