    Abstract: Fuel storage and delivery systems for compressed natural gas are provided that are constructed from ultra-high strength, low alloy steels containing less than 2.5 wt % nickel and having a tensile strength greater than 900 MPa (130 ksi). A primary benefit is that systems of this invention have substantially lower weight than that of currently available steel-based systems. Consequently, the fuel efficiency of a CNG vehicle can be improved due to the lower weight of the system of this invention, or the driving range of the CNG vehicle can be improved by increased fuel storage for the same volume at an elevated pressure, or the load-carrying capacity of the CNG vehicle can be improved. Another primary benefit is that systems of this invention have a cost per unit strength substantially lower than that of currently available systems.

    Abstract: A corrosion protection device (“CPD”) for inhibiting corrosion of an air compressor collection tank, and relieving the pressure in the tank when excessive condensate accumulates within the tank. A relief passage extends through the plug, and an anode seals the relief passage near the interior volume of the tank. The tank, plug and anode are all coupled in an electrically conductive relationship, and a galvanic circuit is formed when condensate collects near the bottom of the tank. The anode has a lower redox potential than steel, and is preferably made from magnesium. The anode loses electrons with less resistance than the steel tank, so the anode will be consumed through the oxidation process before the steel tank corrodes. Once the anode is consumed so that it no longer seals the relief passage, the condensate and air are discharged from the tank through the relief passage.

    Abstract: A mounting structure, for a plurality of high pressure gas vessels (11a, 11b), has a block-shaped vessel mounting member (1) with a high rigidity formed with accommodating portions (5a, 5b, 9a, 9b) for accommodating first neck portions (12a, 12b) formed at one sides of the plural high pressure gas vessels and vessel base-valves (13a, 13b) and formed with a gas flow passage (6) that opens at openings (7a, 7b) of right and left side walls of the vessel mounting member (1) to allow the accommodating portions to communicate with one another. The neck portions (12a, 12b) and the vessel base-valves (13a, 13b) at the one sides of the plural high pressure gas vessels are accommodated in the accommodating portions (5a, 5b, 9a, 9b) of the vessel mounting member 1, and the plural high pressure gas vessels are mounted in the vessel mounting member (1), enabling the gas flow passage 6, formed in the vessel mounting member (1), to serve as a high pressure conduit portion.
