Provided is a saddle type fuel tank in which liquid fuel does not reach a canister through an exhaust passage immediately after full-tank refueling. The saddle type fuel tank includes a saddle type tank body and a full-tank regulating valve. The full-tank regulating valve includes a valve body, a float valve, a first hanging pipe communicatively connected to the valve body and having a first opening at a hanging end thereof, and a second hanging pipe communicatively connected to the valve body and having a second opening at a hanging end thereof. The first opening of the first hanging pipe is located at a height corresponding to a full-tank liquid level RA1_full in the first chamber. The second opening of the second hanging pipe is located at a height lower than that corresponding to a full-tank liquid level RA2_full in the second chamber.

A motor vehicle tank comprises a main tank that includes at least one main extraction unit that has a main flow line for extracting fuel from the main tank; an auxiliary tank arranged adjacent to and connected with the main tank, the auxiliary tank including: an auxiliary extraction unit having an auxiliary flow line for extraction of fuel from the auxiliary tank, and a filler connection for direct filling of the auxiliary tank; a partition wall which separates the auxiliary tank from the main tank by a partition wall, the partition wall having a lower partition wall region without an opening in an installation position, and an upper partition wall region having at least one opening to form an overflow between the auxiliary tank and the main tank.

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 fuel storage assembly includes a power source, a first tank, a fuel pump, an electric relay, a second tank, and a shut-off device. The fuel pump is adapted to remove fuel from the first tank. The electric relay is electrically connected between the power source and the fuel pump for terminating electric power to the fuel pump. The second tank is adapted to receive the fuel removed from the first tank. The shut-off device is located in the second tank and is electrically connected to the electric relay, and is configured to detect a shut-off level of fuel in the second tank. Upon detection of the shut-off level, the shut-off device effects shut-down of the fuel pump via the electric relay.

A variable inlet device for a vehicle includes a first pipe and a second pipe arranged in parallel to each other, and a variable injection pipe configured to allow an exit thereof to be selectively connected to an entrance of the first pipe or an entrance of the second pipe by a rotation movement and a back and forth movement.

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.

A fuel system for supplying gaseous fuel to a power plant comprises a tank array comprising at least first and second tanks, each tank being configured to receive pressurised gaseous fuel for supply to the power plant; and an auxiliary control fluid delivery system. The auxiliary control fluid delivery system comprises a reservoir of auxiliary control fluid; an auxiliary control fluid pipeline, configured to enable supply of the auxiliary control fluid to the tank array so as to cause discharge of the gaseous fuel held in the tank array and to enable return of the auxiliary control fluid from the tank array; and a valve arrangement which is operable to control the supply and return of auxiliary control fluid to and from the tank array, respectively, so as to control the discharge of the gaseous fuel.

A fuel tank system is provided. In the main tank of the system, the end of a communication pipe is located above the end of a fuel introduction pipe inserted into the main tank. The end of a first pressure relief pipe at which a first cut-off valve is provided is located above the end of the communication pipe. In the auxiliary tank, the end of the communication pipe is located above the end of the fuel introduction pipe inserted into the auxiliary tank. In the auxiliary tank, the end of a second pressure relief pipe at which a second cut-off valve is provided is located above an end of a scavenging pipe.

Provided is a saddle type fuel tank in which liquid fuel does not reach a canister through an exhaust passage immediately after full-tank refueling. The saddle type fuel tank includes a saddle type tank body and a full-tank regulating valve. The full-tank regulating valve includes a valve body, a float valve, a first hanging pipe communicatively connected to the valve body and having a first opening at a hanging end thereof, and a second hanging pipe communicatively connected to the valve body and having a second opening at a hanging end thereof. The first opening of the first hanging pipe is located at a height corresponding to a full-tank liquid level RA1_full in the first chamber. The second opening of the second hanging pipe is located at a height lower than that corresponding to a full-tank liquid level RA2_full in the second chamber.

A variable inlet device for a vehicle includes a first pipe and a second pipe arranged in parallel to each other, and a variable injection pipe configured to allow an exit thereof to be selectively connected to an entrance of the first pipe or an entrance of the second pipe by a rotation movement and a back and forth movement.
