The Ford Global Technologies, Inc. patent solves the following problem:

In general, because cars emit volatile fuel vapors into the atmosphere, established regulations requiring fuel system vapor management that includes all vehicles to prevent or otherwise mitigate these emissions. Typical fuel vapor management system includes a carbon filled canister to absorb flammable fuel vapors, and a half-operated vent valve and control arrangement for routing the flow of fuel to the cloud even carbon filled canister or drinking machine for proper combustion.

Our analysis of this patent is as follows:

Ford Global Technologies, Inc.’s patent US 5878727 A deals with Method and system for estimating fuel vapor pressure.
A method for estimating fuel vapor pressure includes determining (102) in an amount of fuel in a fuel tank, enthusiastically pumping (104) a vapor mixture from the tank fuel until a predetermined gauge pressure is obtained, and measuring (108) the time required to reach the predetermined gauge pressure. Fuel vapor pressure is directly quantified (108) based on the measured time and the detected fill level. Thus, an estimate of the fuel vapor pressure can be obtained without need information on fuel temperature, or addition of any dedicated sensor circuitry in a conventional on-board vapor management / system leak detection.
