Abstract: A method and system is disclosed for delivering a cryogenically stored fuel in a gaseous state into the air intake system of a gaseous fuelled internal combustion engine. The method comprises determining the flow rate capacity in the engine system's fuel delivery line, comparing the determined flow rate capacity to a required flow rate demand and supplying fuel in gaseous state directly from the vapor space of the cryogenic storage vessel to the fuel delivery line that supplies fuel to the engine, when the flow rate capacity is equal to or higher than the required flow rate demand. The method further comprises activating a cryogenic pump to deliver fuel to the internal combustion engine from the liquid space of the cryogenic storage vessel when the determined flow rate capacity is lower than the required flow rate demand.

Abstract: A system and method pumps process fluid from a cryogenic storage vessel to a vaporizer, and delivers the fluid as a pressurized gas. The method includes measuring process fluid temperature after the process fluid exits the vaporizer, temporarily suspending operation of the pump when the process fluid temperature is below a threshold temperature, and restarting a suspended pump if at least one predefined enabling condition is satisfied and process fluid pressure is less than a high pressure threshold. The system comprises components that cooperate with one another to execute the method, including a storage vessel, a pump, a vaporizer, a conduit for delivering a pressurized gas from the vaporizer to the end user, a pressure sensor and a temperature sensor for measuring process fluid properties within the conduit, and a controller for commanding operation of the pump responsive to temperature and pressure measurements.

Abstract: An improved apparatus and method provide a portable fuel supply for a vehicle. The apparatus comprises a vessel that is a source of fuel and a conduit that is operatively connected with the vessel at one end. There is also a coupling pin arrangement connected with the vessel. The coupling pin arrangement comprises a coupling pin and is mutually engageable with a fifth wheel coupling device. An end opposite the one end of the conduit operatively connects with a fuel system of the vehicle such that the vessel is in fluid communication with the fuel system and the vehicle operates with the fuel from the vessel.
