摘要: The invention relates to a sampling container for taking samples from a tank containing a flammable liquefield gas. The container comprises an inlet opening and an outlet opening, at least two valves for operating the openings, and a connector at the inlet opening for establishing fluid communication with the tank. A nozzle which communicates with the inlet opening and which suppresses the splashing of liquefied gas flowing into the sampling container and hence the build-up of static electricity. The invention further pertains to an apparatus for taking samples from a tank containing a flammable liquefied gas, comprising a first connector-counterpart for receiving the connector of the sampling container.

摘要: A supply plenum and valve body assembly (40) connected to a source of compressed natural gas (CNG) selectively turns on the flow of CNG through either a first sonic nozzle (52) or a second sonic nozzle (54) and out through respective dispensing hose assemblies (28, 30). A pressure transducer (96), a supply plenum temperature transducer (118), and an ambient temperature transducer (91) measure the stagnation pressure and temperature of the CNG and the ambient temperature, respectively. A pressure transducer (92) fluidically connected to the vehicle tank via the dispensing hose assembly monitors the pressure of the CNG in the vehicle tank. An electronic control system (13) connected to the pressure and temperature transducers and to the supply plenum and control valve assembly (40) calculates a vehicle tank cut-off pressure based on the ambient temperature and on the pressure rating of the vehicle tank that has been pre-programmed into the electronic control system (13), calculates the volume of the vehicle tank and the additional mass of CNG required to increase the tank pressure to the cut-off pressure, and automatically turns off the CNG flow when the additional mass has been dispensed into the vehicle tank. The electronic control system (13) also determines the amount of CNG dispensed through the sonic nozzles (52, 54).

摘要: The invention relates to a fuel storage system for storing dimethylether (DME), a blend including DME, or other similar highly volatile fuel on a vehicle. The fuel storage system comprising a main storage tank (11), an expansion tank (12), a fuel filling receptacle (13) configured to receive a fuel filling nozzle (22) of a filling station, and a valve arrangement (16) having at least a normal operating setting and a fuel filling setting. The valve arrangement (16) in the normal operating setting provides a fuel passage between the main storage tank (11) and the expansion tank (12), and the valve arrangement (16) in the fuel filling setting both provides a fuel passage between the fuel filling receptacle (13) and the main storage tank (11) and prevents fuel flow between the main storage tank (11) and the expansion tank (12). The fuel storage system is configured to mechanically prevent disconnection of the fuel filling nozzle (22) from the fuel filling receptacle (13) unless the valve arrangement (16) is in the normal operating setting. The invention also relates to a corresponding method, as well as a further example embodiment of the fuel storage system.

摘要: 燃料タンク10A、10Bの一つで燃料の充填が停止した後、燃料タンク10A、10B全体への充填を高流量充填とし、次に、燃料タンク10A、10Bの二つ目の燃料充填量がこの燃料タンク10A、10Bの減速用充填量に到達したときに、燃料タンク10A、10B全体への充填を低流量充填とし、二つ目の燃料タンク10A、10Bの燃料充填量がこの燃料タンク10A、10Bの停止用充填量に到達したときに、二つ目の燃料タンク10A、10Bの充填を停止させる。これにより、長距離走行等に対しての積載燃料量を確保するために、燃料タンクを複数搭載するDME燃料使用の自動車に対しても、簡素な制御でしかも低コストで、燃料充填時において、複数の燃料タンクに同時に燃料充填しながら、燃料供給停止時の衝撃波の発生を容易に回避できるDME燃料の燃料タンクへの燃料充填方法と燃料充填システムを提供する。

摘要: Disclosed is a simple, analytical method that can be utilized by hydrogen filling stations for directly and accurately calculating the end-of-fill temperature in a hydrogen tank that, in turn, allows for improvements in the fill quantity while tending to reduce refueling time. The calculations involve calculation of a composite heat capacity value, MC, from a set of thermodynamic parameters drawn from both the tank system receiving the gas and the station supplying the gas. These thermodynamic parameters are utilized in a series of simple analytical equations to define a multi-step process by which target fill times, final temperatures and final pressures can be determined. The parameters can be communicated to the station directly from the vehicle or retrieved from a database accessible by the station. Because the method is based on direct measurements of actual thermodynamic conditions and quantified thermodynamic behavior, significantly improved tank filling results can be achieved.
