compressed natural gas fuel tank system
Tariff Classification of a compressed natural gas fuel tank system. The merchandise at issue is a compressed natural gas (“CNG”) fuel tank system (“FTS”). The fuel tank system consists of a CNG storage tank and an integrated fuel management module (“FMM”). The CNG storage tank is constructed of resin-impregnated, continuous filament, carbon fiber composite material with a plastic liner. The storage tank is a cylinder with a volume of 141.1 gallons and a CNG volume of 5049 standard cubic feet. The cylinder is fitted with a shut-valve which can be used to manually disable the flow of gas.
The FMM houses the CNG control components. The components include a quarter-turn shut-off valve, high volume and standard fill receptacles, and a high pressure gauge. The quarter turn shut-off valve shuts off the gas flowing from the FMM to the engine. The two receptacles are used when filling the tank. The high-pressure regulator reduces the gas pressure for delivery to the engine. The coolant ports allow warm coolant from the engine to be circulated through the high-pressure regulator to prevent freezing. The CNG tank is covered by a protective shroud that is custom-configured to the vehicle, and is designed to protect the components of the system. The entire fuel tank system is mounted to the side of a truck. The fuel tank system is specially designed for use with trucks with spark-ignition engines that operate using a supply of CNG. The following are images of the FTS and the FTS mounted on a truck:
