Abstract: Methods are provided for correct spill valve timing of a high pressure pump coupled to the direct injection system of an internal combustion engine. A method is needed to monitor and adjust spill valve timing on-board the vehicle, where spill valve timing error may result from sensors error and/or time between command signal and actuation response of the spill valve. To self-correct spill valve timing error on-board a vehicle, methods are proposed that involve monitoring and recording fuel rail pressures, high pressure pump duty cycles, and fractional liquid volume pumped values in order to find zero flow relationships.

Abstract: An automotive fuel pump having a body with an inlet, an outlet, and an elongated chamber therebetween. A relief valve, relief valve housing, and check valve are respectively disposed in the chamber between the inlet and the outlet. The relief valve housing has a portion which extends across the chamber so that a first axial end of the relief valve housing forms a valve seat for the check valve while the other axial end forms a valve seat for the relief valve. The check valve permits fluid flow from the body chamber to the outlet while the relief valve exhausts excess fluid pressure at the outlet back into the body chamber.

Abstract: A pump unit for a fuel injection system is disclosed. The pump unit has a low pressure fuel supply line and a high pressure fuel outlet. A pumping chamber having a plunger is operable to perform a pumping cycle comprising a pumping stroke and a filling stroke. The pump unit also includes an inlet valve having an inlet valve member movable between an open position for permitting the supply of fuel to the pumping chamber from the low pressure fuel supply line and a closed position for inhibiting the supply of fuel from the pumping chamber to the low pressure supply line. An outlet valve is provided in the high pressure fuel outlet. The pump unit also includes means for coupling the plunger to the inlet valve member. The present application also relates to a method of operating a pump unit; and a valve for a fuel injection system.

Abstract: Methods are provided for rapid zero flow lubrication of a high pressure fuel pump, wherein a fuel rail pressure rapidly responds to commanded duty cycles. A method is needed to control operation of the high pressure pump during times when no direct injection is requested by an engine system and when operation of the high pressure pump is continued to maintain pump lubrication. To lubricate the high pressure pump while gaining zero flow rate data, methods are proposed that involve both open and closed loop control of the high pressure pump.
