Abstract
Disclosed is a fuel injection mechanism having a horizontal control surface formed within a plunger for regulating the start of fuel injection. The horizontal control surfaces are formed within one or more of the two opposed ridges formed within the plunger defining a recessed channel there between. The horizontal control surfaces of the ridges regulate the opening and closing of the ports formed within the bushing of the injector. The horizontal control surfaces contribute to reduced wear and provide for accurate timing and fuel quantity delivery.
