Beschreibung
Zusammenfassung:	Improved methods, systems, and devices for filling fuel tanks, particularly compressed natural gas (CNG) fuel tanks, are provided. Such methods, systems, and devices lower the heat of compression when the fuel tank is being filled to a temperature lower than that if such methods, systems, and devices were not used. Pressure sensor logic on a fuel station will be less prone to error, enabling the tank to be filled more accurately and fully. To lower heat of compression, an insert is placed within the tank. The insert changes the flow characteristics of the fuel that is being delivered into the tank. Typically, the delivered fuel will be released into the interior of the tank in a vortex fashion to fill the tank. Other flow modification devices are also provided including an externally coupled Ranque-Hilsh vortex tube and a flow modification chamber built within a fuel tank.
