The present disclosure generally relates to a multiple receptacle fuel filling and storage system in a vehicle and/or powertrain, and a method of using the same.

A multiple storage tank system includes: storage tanks in which cryogenic fluid is stored; discharge lines connected to the storage tanks to discharge the stored cryogenic fluid or introduce cryogenic fluid; a supply line connected to the discharge lines and a supply target to supply the discharged cryogenic fluid to the supply target; a build-up line branching off the supply line to control internal pressure of a first storage tank of the storage tanks; and a gas transfer line connected to the storage tanks to transfer gas inside the storage tanks, wherein when the internal pressure of the first storage tank is controlled while the cryogenic fluid passes through the build-up line, gas inside the first storage tank is transferred to at least one other storage tank through the gas transfer line so that internal pressure of the at least one other storage tank is controlled.

This invention is a sensor probe, generally used in the oil fracking business, and includes structurally a pair of tube members, concentrically assembled, an inner housing tube, and an outer spout tube, affixed to a cap and adaptor, with the inner housing holding one or more sensors, to detect the level of fuel within the fuel tank of the fracking truck. The adaptor has a first aperture for attachment of the fuel line, for delivery of fuel in the space between the tube members, and the adaptor has a second aperture for connection of an electrical receptacle, for attachment with the electric lines leading from the various sensors, to the adaptor, for connection with a circuit line from a remote monitor.

A fueling system for an engine includes a fuel tank, a controller, a fuel nozzle receptacle connected to the fuel tank, the fuel nozzle receptacle including a receptacle sensor configured to send a signal to the contoller indicative of whether a fuel nozzle of a fuel dispenser is received in the fuel nozzle receptacle, and an electric fill slop valve between the fuel tank and the fuel nozzle receptacle, the electric fill stop valve being, configured to be controlled to open and close in response to a signal from the controller. The controller can be configured to receive at least one of (a) a signal whether a fuel nozzle of a fuel dispenser is received in a fuel nozzle receptacle connected to the fuel tank, and (b) a signal whether a fuel level of the fuel tank is full, and to control the electric fill stop valve to close when a signal is sent to the controller that at least one of (a) the fuel nozzle is not received in the fuel nozzle receptacle when the controller is configured to receive the signal whether the fuel nozzle of a fuel dispenser is received in the fuel nozzle receptacle, and (b) the fuel level of the fuel tank is full when the controller is configured to receive the signal whether the fuel level of the fuel tank is full.

The fuel gas system (100) for a vehicle (1) comprises: —a filling device (50) having an outlet pipe (56); —a first circuit (11) for providing fuel gas to an engine (8) of the vehicle, and including: —a first tank (12); —a first supply line (13) connecting the first tank (12) and the engine (8); —a first filling pipe (14) connecting the filling device outlet pipe to the first tank (12); —a second circuit (21) for providing fuel gas to a thermic device (9) capable of heating, cooling or refrigerating, the second circuit (21) including: —a second tank (22); —a second supply line (23) connecting the second tank (22) to the thermic device (9); —a second filling pipe (24) connecting the filling device outlet pipe (56) to the second tank (22). The first circuit (11) and the second circuit (21) are configured to be in fluid communication: —in a filling phase, when fuel gas flows in the first and second filling pipes (14, 24) from the filling device (50) towards the first and second tanks (12, 22); —and in a working phase, when fuel gas flows in the first and second supply lines (13, 23) from the first and second tanks (12, 22).

A fuel tank system is provided with at least two separate tank bodies, each with a respective tank body interior, and a connecting element connecting the tank bodies for fluid communication. The tank bodies are connected to each other by means of a connector and are fabricated from a plastic material. The fuel tank system is formed with receiving means (5) for arrangement on a frame of a vehicle, such as a motorcycle, having a driver's saddle. The fuel tank system includes a distributor element with a fuel filling opening; the distributor element is connected in a fluid-conducting manner to the tank bodies via at least one fluid-conducting connector.

A transport refrigeration system having: a refrigerated cargo space (119); a refrigeration unit (22) in operative association with the refrigerated cargo space, the refrigeration unit providing conditioned air to the refrigerated cargo space; a first engine (150) configured to power the vehicle; a second engine (26) configured to power the refrigeration unit; a first plurality of fuel tanks (350) fluidly connected to first engine, the first plurality of fuel tanks configured to supply fuel to the first engine; a second plurality of fuel tanks (330) fluidly connected to second engine, the second plurality of fuel tanks configured to supply fuel to the second engine; and a single filling point (310) fluidly connected to the first plurality of fuel tanks and second plurality of fuel tanks. The single filling point (310) is configured to receive fuel.

The present disclosure relates to a saddle tank for motor vehicles, having two chambers connected to one another in their upper region via a central portion having a reduced cross-section, wherein the first chamber has an access opening for refueling and wherein a fill level-limiting valve is arranged in the second chamber. In order to prevent unwanted swash-over of fuel from the first chamber into the second chamber, provision is made according to the invention for there to be arranged, between the two chambers, a separating body which has a separating wall, which extends over the entire width of the central portion between an upper and a lower wall portion, and a pipe which extends from an opening in the separating wall into the first chamber and allows fluid communication between the first and the second chamber.

Methods and systems are provided for increase a rate at which a saddle fuel tank is depressurized responsive to a request for refueling. In one example, a method may include, responsive to the request for refueling, depressurizing a primary side of the saddle fuel tank to a secondary side of the saddle fuel tank, and commanding open a refueling lock coupled to the primary side to allow fuel to be delivered to the primary side when pressure in the primary side drops below a threshold pressure. In this way, the secondary fuel tank may be maintained at atmospheric pressure prior to the request for refueling, which may increase the rate of depressurization of the saddle fuel tank responsive to the request.
