Abstract

A fuel supply system for an internal combustion engine, particularly of a motor vehicle, includes a control unit for determining a fuel quantity to be injected, the fuel quantity to be injected being initially increased during a start of the internal combustion engine and then being reduced again. The fuel supply system also includes a fuel injector for injecting the fuel quantity to be injected into a combustion chamber. It is checked by the control unit whether a combustion has taken place in the cylinder, and, if no combustion has taken place, the fuel quantity to be injected is not reduced, or is not reduced to the same extent as when a combustion has taken place.
