Abstract
Electrically controlled fuel injection systems should be able to operate at low voltage. In order to operate an electrically controlled fuel injection system at low voltage, the voltage available to an electrical actuator is monitored. The electrical actuator is coupled to a valve positioned within a passageway in which high pressure actuation fluid flows to and from an hydraulically actuated device, such as a fuel injector and/or an engine brake. If the voltage available to the electrical actuator falls below a predetermined voltage, the pressure differential across the valve is reduced. Although the principal application of the present invention is in the fuel injection system, the present invention has application in any electrically controlled fluid system at low voltage.
