Abstract

PURPOSE: To improve accuracy in the control of fuel supply remarkably, by controlling operation of fuel injection valves depending on the operational condition of engine, and also controlling the opening of an electromagnetic fuel metering valve by a pressure sensor for detecting the pressure of fuel in an accumulator.
CONSTITUTION: High-pressure fuel pre-pressurized by a feed pump 10 and then compressed to a high pressure by a plunger pump 11 is stored, under pressure, temporarily in an accumulator 13, the pressure of fuel in which accumulator 13 is controlled by an electromagnetic fuel metering valve 12. The high-pressure fuel from accumulator 13 is supplied to fuel injection valves 6, operation of which is controlled by a control circuit 16 on the basis of the output signals from a sensor 42 for detecting the amount of intake air, a sensor 44 for detecting the rotational angle of engine, a sensor 45 for detecting the temperature of engine cooling water, a fuel-temperature sensor 46, etc. Here, the signal relating to the pressure of fuel in accumulator 13 is fed back to control circuit 16 as an output of a potentiometer 23.
