DEFINITION

Classification: 123/472

Electrically actuated injector:

(under subclass 445) Subject matter in which the fuel injection system includes a valve means that is electrically actuated to control the flow of pressurized fuel into the engine intake or combustion chamber, and further includes switching means to direct electrical current to actuate the injection valve.
