A system and method for controlling the fuel pressure in a common rail fuel injection system which electronically controls a variable output high pressure pump based upon engine speed, torque and actual common rail pressure inputs, as well as the present system voltage, thereby providing simple yet stable control of the fuel pressure in the accumulator of the common rail system which is relatively insensitive to supply voltage fluctuations from the power source providing the electrical power to the solenoid-controlled valve which controls the high pressure pump. |
