ABSTRACT:
A fuel injector having an orifice plate proximate the outlet. The orifice plate has first and second plate surfaces spaced at a predetermined distance from one another and an orifice, the orifice extending along a longitudinal axis and includes a first surface and a second surface being spaced from the first surface. The first surface includes a first region having a first surface characteristic being oriented in a first direction oblique to the longitudinal axis. The second surface includes a second region having second surface characteristic being oriented in a second direction oblique to longitudinal axis. The fuel injector has a housing extending a longitudinal axis. The housing includes an inlet, an outlet and a passageway disposed between the inlet and the outlet. The fuel injector further includes an electromagnetic actuator proximate the inlet, the electromagnetic actuator including an armature and an electromagnetic coil, a valve assembly, the valve assembly including a closure member and a valve seat, the closure member operable to occlude fuel flow to the outlet in a first position and operable to permit fuel flow to the orifice plate in a second position.
