Title: Direct fuel injection using a fuel pump driven by a linear electric motor

Abstract: A fuel delivery system for an internal combustion engine having a plurality of combustion chambers. The fuel delivery system includes a source of fuel, a fuel pump driven by a linear electric motor, a plurality of fluid actuators and a plurality of fuel delivery assemblies. The fuel pump driven by a linear electric motor draws fuel from the source of fuel and pumps the fuel to the plurality of fluid actuators. The fluid actuators direct the fuel to fuel delivery assemblies. The fuel delivery assemblies receive the fuel from the fluid actuators and deliver the fuel to combustion chambers. The fuel delivery system includes a control system that controls the operation of the fuel delivery system to provide desired volumes of fuel at desired flow rates to the combustion chambers.
