Method and apparatus for determining the volume of fuel in a vehicle fuel tank |
摘要 |
A method of determining the volume of fuel in a vehicle fuel tank comprising the steps of determining the volume of vapor/air in the fuel tank and calculating the volume of fuel in the tank based upon the determined volume of vapor/air. The volume of vapor/air is determined by the steps of closing the fuel tank, pumping air into or out of the closed volume of the fuel tank and measuring the change in pressure in the fuel tank as a function of time during said pumping to determine the volume of vapor/air in the tank.
