Abstract
An electromagnetic fuel injector has an orificed fuel director plate, mounted downstream of a solenoid actuated valve and an associated main orifice passage opened and closed by the valve, to receive fuel when the valve is pulled to an open position from its associated valve seat for controlling and directing flow from the injector. The upper surface of the orifice director plate is provided with a fuel distributing channel system terminating in separate pairs of cooperating injection orifices that are disposed adjacent to one another to direct adjacent jets of fuel which partially intersect one another producing discrete cones of atomized fuel accurately onto separate fuel intake valves of a piston cylinder of an internal combustion engine.
