  • Pressure control for the fuel system of an internal combustion engine
    Patent number: 4756291
    Abstract: A fuel system for an internal combustion engine wherein the fuel pressure is maintained within a desired predetermined range. An electric fuel pump supplies fuel at a pressure proportional to the electric power applied to the pump. Control circuitry compares a voltage signal corresponding to the fuel pressure within a predetermined voltage range corresponding to a predetermined fuel pressure range. When the voltage signal is below the predetermined voltage range, the electric power applied to the electric pump is increased; when the voltage signal is above the predetermined voltage range, the electric power applied to the electric pump is decreased. The control circuit may further increase or decrease the electric power at a predetermined rate.
