    摘要: A valve assembly in an internal combustion engine fuel system includes a valve member movable within a valve body to contact a valve seat and block fluid communication between first and second passages. The valve seat and valve member each include a multi-layered coating having a harder metal nitride base layer and a softer metal nitride outer layer. The base layer is relatively incompliant to impacts between the valve member and the valve seat, and the outer layer is relatively compliant to the impacts and thereby deformable. Related methodology is disclosed.

    摘要: A fuel injector system includes an injector body having a proximal end and a distal end, the injector body defining a nozzle having an outlet. The injector system includes a spill valve fluidly connected to the outlet and having a spill valve member movable between an open position and a closed position. The injector system includes a control valve including a control valve member movable between an open position and a closed position. The injector system includes a check valve fluidly connected to the outlet, the control valve including a check valve needle movable between an open position and a closed position. The injector system also includes an electrical monitoring circuit configured to output a signal indicative of at least one of the open position or the closed position of the spill valve member.
