Abstract

A variable stroke direct injection (DI) fuel pump system for an engine includes a DI fuel pump having a stroke member and configured to pump a quantity of fuel based on a stroke of the stroke member. The system includes a variable fuel pump actuator assembly comprising an actuator member configured to actuate the stroke member, a control valve configured to control a flow of hydraulic fluid to the actuator member, and a hydraulic fluid pump configured to pump the hydraulic fluid and be actuated by one or more lobes of a camshaft. The system also includes an engine control unit (ECU) configured to control a variable stroke of the stroke member by controlling the control valve based on one or more operating parameters of the engine.
