Abstract

A fuel supply system for an internal combustion engine, in particular of a motor vehicle, is equipped with a pressure accumulator and a high-pressure pump with which fuel can be delivered to the pressure accumulator. Also provided is a control device with which at least the pressure in the pressure accumulator can be controlled. When the internal combustion engine is in coastdown (overrun) mode, the pump output of the high-pressure pump can be reduced.
