Abstract
A method and a device for exciting pressure fluctuations in a fuel supply system of an internal combustion engine are provided, which in turn enable a determination of the sound velocity of the fuel. A quantity that characterizes the pressure in a fuel storage device or a fuel line is evaluated. In at least one operating state of the internal combustion engine, a natural oscillation of the fuel in the fuel storage device or the fuel line is excited.
