ABSTRACT:
A high-pressure, continuous-delivery piston pump, controlled as a function of engine speed and load, supplies fuel to an accumulator supplying injectors. On the intake side of the pump, there is provided a throttle for metering the amount of fuel supplied by the pump. Via operating signals, the throttle is regulated by an electronic control device in such a manner as to supply the pump and pressurize only the amount of fuel strictly required for operating the injectors and the engine, thus eliminating any energy losses caused by fuel feedback to the tank, and drastically reducing fuel consumption.
