Abstract
A bi-fuel vehicle includes an Internal Combustion Engine (ICE) to power the vehicle by combustion of liquid and gas-phase fuels. The vehicle has a dual fuel tank including a pressurizable gas-phase fuel compartment defined by a wall that is permeable by a gas-phase fuel. The gas-phase fuel compartment receives and contains the gas-phase fuel, and supplies the gas-phase fuel for combustion in the ICE. The dual fuel tank includes a liquid fuel compartment to receive and contain liquid fuel, and supply the liquid fuel for combustion in the ICE. A shell envelops the gas-phase fuel compartment, and defines the liquid fuel compartment. An interstitial space between the wall and the shell is in one-way fluid communication with the liquid fuel compartment. The interstitial space receives the permeated gas-phase fuel and channels the permeated gas-phase fuel to the liquid fuel compartment. The dual fuel tank has a vapor recovery system.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
