Title: Fuel supplying device for internal combustion engine

Abstract

A fuel supplying device for an internal combustion engine is disclosed which has a fuel supply passage for introducing fuel fed from a fuel pump at a substantially constant pressure to a fuel injector operative at a predetermined constant pressure. The fuel injector is installed at a congregated portion of engine intake manifolds. A metering valve includes a motor so that the pressure drop is maintained substantially constant by a differential regulator. The metering valve is disposed in an intermediate portion of the fuel supply passage. Calculating means including a servo signal generator calculates an injection flow amount causing a predetermined air/fuel ratio on the basis of signals of various engine running factors. An operational signal output from the servo signal generating circuit of the calculating means is applied to the drive motor means for driving said metering valve to thereby inject fuel into the intake manifolds.
