摘要： A fuel delivery system for a vehicle having an engine configured to selectively operate between a port fuel injection (PFI) mode and a gasoline direct injection (GDI) mode includes a PFI fuel rail having a plurality of PFI injectors configured to supply fuel to the engine during the PFI mode, a GDI fuel rail having a plurality of GDI injectors configured to supply fuel to the engine during the GDI mode, a first GDI fuel supply line fluidly coupled to the GDI fuel rail, a first deactivating GDI fuel pump assembly disposed on the first GDI fuel supply line. The first deactivating GDI fuel pump assembly is configured to selectively transition between an activated mode and a deactivated mode.

摘要： A computer-implemented method can include receiving a contact point path between a rocker arm pad and a valve tip. The method can include adjusting the contact point path to obtain a modified contact point path that satisfies a design objective of decreased valve tip wear or decreased valve tick. The method can include determining and outputting a custom contour for the rocker arm pad and the camshaft lobe based on the modified contact point path. The custom contoured camshaft lobe can companion with the custom contoured rocker arm pad to produce the modified contact point path for the specified design objective.
