ABSTRACT:
A method and apparatus for controlling fuel to be supplied from a motor-driven fuel pump to fuel injection valves of a fuel injected engine, the time period during which the fuel injection valves are kept open and the power duty cycle for driving the fuel pump motor are both calculated by a microcomputer responsive to one or more engine operating conditions. Reduced power consumption of the pump motor is achieved, thus resulting in reduction in the load applied to the battery and therefore improving the fuel consumption rate. The apparatus comprises an input unit, an injector drive unit, and a pump drive unit in addition to the microcomputer, and includes circuits for converting both the time period and the power duty cycle according to the battery voltage and the degree of engine acceleration.
