1. A fuel extraction and pressurization system for delivering a gaseous fuel from a fuel storage system to a fuel injection system of an internal combustion engine, wherein the fuel storage system comprises a tank having an interior in which a sorbent is present and to which the gaseous fuel is adsorbed and wherein the gaseous fuel is at a tank pressure in a tank pressure range of about 1000 psi (7 MPa) to about 10 psi (0.07 MPa), the fuel extraction and pressurization system having an input in fluid connection with the interior of the tank of the fuel storage system and an output in fluid connection with the fuel injection system and comprising one or more vacuum and pressurization components, wherein during operation the one or more vacuum and pressurization components apply a vacuum to the interior of the tank to facilitate the extraction of the adsorbed gaseous fuel from the tank and compress the extracted gaseous fuel thereby providing compressed gaseous fuel at an output pressure and an output flow rate to the fuel injection system for the operation of the internal combustion engine at or about the stoichiometric air-fuel ratio for the gaseous fuel at any selected throttle position for the internal combustion engine, regardless of the tank pressure within the tank pressure range, wherein the one or more vacuum and pressurization components are selected from the group consisting of a vacuum pump, a compressor, or a vacuum pump and a compressor. |
