Claims

[Scope of utility model registration request]

In a fuel supply device for an internal combustion engine, which includes an electromagnetic fuel injector and controls the amount of fuel supplied by controlling the valve opening time of the injector, there is provided a means for detecting the fuel supply pressure of the injector, and the fuel supply pressure. 1. A fuel supply system for an internal combustion engine, comprising: control means for increasing the valve opening time of an injector/lid when the valve opening time of an injector/lid is abnormally reduced.
