Abstract
A fuel injector of the type in which a valve hole is opened and closed by a valve so as to intermittently inject pressurized fuel from the valve hole includes a distributing adapter fixedly attached to a front end of the valve hole, and an air adapter fixedly attached to a front end of the distributing adapter. The air adapter is formed with a plurality of guide holes directed to a plurality of intake ports of the engine, respectively, and assist air passages each communicating laterally with a corresponding one of the guide holes. The distributing adapter is formed with distributing holes of the same number as the guide holes, each of the distributing holes extending between the valve hole and a corresponding one of the guide holes.
