摘要：
A procedure for determining the vapor pressure of a fuel in a tank is provided, whereby the sound velocity and/or a variable representing the sound velocity are determined the in the gas-filled compartment of the tank and the vapor pressure is assumed from the sound velocity and/or from the variable representing the sound velocity at a familiar total pressure.
