초록 ▼

A fuel supply system for an engine having no fuel return pipe is disclosed. In steps target fuel is set according to an engine operating state. Thereafter, a target current value to be supplied to the motor of a fuel pump according to the target fuel pressure is obtained. In the succeeding step, an actual motor current is detected and, then, the target current value and the detcted current are compared. Thereafter, the supply current is controlled by feedback based upon the difference obtained by comparison between the target current value and the detected current value to eliminate the difference.

대표청구항 ▼

[ What is claimed is:] [1.] A fuel supply system for an internal combustion engine, said system comprising:an electronically pulse-width controlled fuel injection valve;a delivery pipe disposed for supplying fuel to said fuel injection valve;a fuel pump driven by a dc electric motor disposed for feeding fuel to said delivery pipe at a controlled pressure;a motor driving circuit arranged to supply driving current to said electric motor;first means storing data representing a relationship between target fuel pressure and engine operating conditions, which conditions include intake air amounts and engine speeds, for providing a target current value for said dc motor and a target flow rate value for fuel to be injected by said fuel injection valve according to said engine operating conditions;second means for detecting the driving current supplied to said electric motor;third means for correcting said driving current towards said target current value; andfourth means for compensating differences between a flow rate of fuel injected by said injection valve and said target flow rate value according to said stored relationship thereby driving said fuel pump to feed fuel at said controlled pressure.
