    摘要： A method of operating a vehicle powertrain includes determining a selected powertrain operational mode. A demand fraction is determined. An internal combustion engine (ICE) is to output a maximum power when a gaseous fuel is conveyed to an injector of the ICE at a source pressure greater than a cutoff pressure. The source pressure in a container in fluid connection with the injector is determined. The gaseous fuel is received at the source pressure by the injector to inject the gaseous fuel into the ICE for combustion in response to the source pressure, demand fraction, or selected powertrain operation mode meeting a first set of criteria. The injector is prevented from injecting the gaseous fuel into the ICE and the powertrain is driven from an alternative power source in response to the source pressure, demand fraction, or selected powertrain operation mode meeting a second set of criteria.

    摘要： A method for increasing capacity of a natural gas (NG) tank. The method includes selecting a container with a service pressure rating of about 3,000 or 3,600 psi. An NG adsorbent is in the container. The container has a maximum fill capacity. The method further includes cooling the adsorbent by Joule-Thomson cooling during filling of the container with NG from a filling source at greater than 3,600 psi. The container is filled to the maximum fill capacity at a fill rate to prevent a bulk temperature of the adsorbent from rising more than about 5° C. above an ambient temperature. A rate of heat transfer from the tank is less than a rate of heating from compression of the NG and adsorption during the filling. The NG adsorbent adsorbs a higher amount of NG than it would at higher than 5° C. above ambient.

    摘要： A method of storing and using natural gas (NG) in a vehicle includes selecting a vehicle having an NG tank for fueling an engine of the vehicle. The tank service pressure rating is 3600 psi (pounds per square inch) and an NG adsorbent is in the tank. A first quantity of NG is transferred into the tank from a first source having a first source pressure less than 725 psi. The adsorbent adsorbs a portion of the NG. After transferring the first quantity of NG, the engine is operated until NG is desorbed and consumed by the engine. NG is transferred into the tank from a second source to fill the tank to a second tank pressure of about 3600 psi. The adsorbent adsorbs some of the NG. After transferring the second quantity of the NG, the engine is operated until NG is desorbed and consumed by the engine.

    摘要： A natural gas storage system includes a container, a natural gas adsorbent positioned in the container, and a heating mechanism operatively positioned to selectively thermally activate the adsorbent. A method for improving efficiency of the natural gas storage system is also disclosed. A predetermined percentage of a capacity of the container for natural gas remaining in the container is identified. In response, a heating mechanism operatively positioned to selectively thermally activate the adsorbent is initiated. The adsorbent is heated and buffer adsorbed gas is released from the adsorbent.
