Abstract
A mechanically pressurized electronic fuel injector for use in internal combustion engines is actuated by the engine valve train during the injection stroke. A control solenoid is mounted to the injector and has its axis inclined with respect to the axis of the injector. A control valve passage has its axis generally coaxial with the central axis of the control solenoid. Machining of the control valve passage is accomplished through the receiving boss for the control solenoid. High pressure sealing plugs, previously required to seal orifices in the exterior surface of the injector body which were needed to provide access to drill or machine the control valve passage, are completely eliminated. The drilling and machining of the control valve passage is accomplished without drilling through the exterior surface of the injector body.
