Abstract
A fuel injector including a body having an inlet, an outlet, and a fuel passageway extending from the inlet to the outlet along a longitudinal axis. An armature is proximate the inlet of the body. A needle is operatively connected to the armature. A seat is proximate the outlet of the body. A guide member is disposed within the body, the guide member including an aperture that guides the needle. A flat metering disk is disposed between the seat and the guide member, the flat metering disk including a central aperture, a perimeter, and a plurality of slots. Each of the plurality of slots is disposed about the central aperture and extends from the central aperture toward the perimeter to define a volume. The plurality of slots are configured so that the volumes of two of the plurality of slots are non-uniform, and/or the plurality of slots are non-uniformly disposed about the central aperture.
