Embodiment Construction

[0029] Natural gas vehicles are fitted with on-board storage tanks. Some natural gas storage tanks are designed as low pressure tanks. Low pressure natural gas tanks are normally rated up to about 750 psi. For example, low pressure tanks for low pressure systems may be rated for pressures of approximately 725 psi and lower. In other examples, low pressure tanks for low pressure systems may be rated up to pressures in the range between approximately 300 psi and 1000 psi. During refueling, the container of the low pressure system storage tank is designed to fill until the tank reaches a pressure within the specified range. Low pressure system storage tanks are generally not designed to be pressure rated above the specified range. In contrast, other natural gas storage tanks are designed as high pressure tanks. High pressure natural gas tanks are normally rated in the range of about 3000 psi (207 bar or 20.7 MPa (megapascals)) to about 3600 psi (248 bar or 24.8 MPa). Similar...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application 61 / 806,141, filed March 28, 2013, the entire contents of which are incorporated herein by reference. Background technique [0003] Natural gas fueled vehicles have on-board tanks for storing natural gas. The on-board natural gas storage tank can typically be refueled at a high pressure (commercial / fleet) fueling station or at a low pressure fueling station which may be located, for example, in a residential area. Typically, on-board natural gas storage tanks on vehicles are optimized for replenishment at low or high pressure stations. Standard nozzles for high-pressure fuel stations are not compatible with refueling refueling receptacles on vehicles designed for low-pressure natural gas systems to avoid exceeding the operating pressure of the low-pressure natural gas system. Contents of the invention [0004] A method of storing and using natur...
