A vehicle underbody structure includes a pair of rockers that are provided on both vehicle width direction sides of a vehicle underbody and extend in a vehicle front-rear direction, a battery that is disposed centrally in a vehicle width direction center between the pair of rockers and is disposed above a vehicle floor and on the lower side of a seat, a fuel tank that is disposed in the vehicle width direction center between the pair of rockers and is disposed under the vehicle floor and further toward a rear side of the vehicle than the battery, and a waste pipe that is coupled to a drive unit provided at a vehicle front side of the battery and extends in the vehicle front-rear direction between the battery and one of the rockers.

A diesel fuel and DEF combination tank provides a supplemental storage of diesel fuel and DEF for a vehicle. In particular, the combination tank comprises a first compartment for diesel fuel and a second compartment for DEF. Each compartment is provided with a respective outlet port for dispensing the fuel from the combination tank. Dispensing of fluid to the vehicle's fuel system is conducted by gravity feed or alternatively by pumping.

An apparatus and a method are provided for a compressed natural gas fuel system configured to replace a motor vehicle's fuel system comprising a storage assembly comprising an enclosure, wherein the enclosure contains a plurality of tanks configured to contain compressed natural gas; and a chassis disposed within the enclosure and configured to retain the plurality of tanks, wherein the storage assembly is configured to be mounted to the roof of a motor vehicle.

A vehicle floor structure may include a floor disposed on a bottom portion of a vehicle body; a plurality of tank mounting members attached to a bottom surface of the floor; and a plurality of hydrogen tanks mounted on the plurality of tank mounting members, wherein each tank mounting member is aligned to extend in a longitudinal direction of the vehicle, the plurality of tank mounting members is spaced from each other in a width direction of the vehicle, each tank mounting member has a plurality of lower recessed portions provided in a lower portion thereof, and at least predetermined upper portions of the hydrogen tanks are received in the lower recessed portions of the tank mounting members, respectively.

A motor vehicle with a pressure vessel system includes at least a first pressure vessel arranged in a first region of the motor vehicle and at least one second pressure vessel arranged in a second region of the motor vehicle having a lower intrusion probability than the first region. Fuel is preferentially removed first primarily from the at least one first pressure vessel. When the lower limit of fuel level or fuel temperature is reached in the at least one first pressure vessel, fuel is removed from the at least one second pressure vessel. If the fuel supply rate from the at least one first pressure vessel is lower than an overall fuel supply rate for an energy converter, fuel is removed from the at least one second pressure vessel to meet the overall fuel supply rate needed by the energy converter.

An engine capable of operating on compressed air includes one or more first pressurized air tanks, one or more second pressurized air tanks, a first motor including a casing, a transmission shaft disposed within the casing, a first motor entry port coupled to the one or more first pressurized air tanks for receiving compressed air, and a first motor exit port for exhausting the received compressed air, a second motor including a turbine housing, a crankshaft, and a turbine for rotating the crankshaft disposed within the turbine housing, a second motor entry port coupled to the one or more second pressurized air tanks for receiving compressed air, and a second motor exit port for exhausting the received compressed air, and an auto clutch for selectively coupling the transmission shaft to the crankshaft.

There is provided a truck, comprising a cab and a plurality of storage tanks secured behind the rear of the cab, wherein the storage tanks are configured to contain hydrogen gas. An energy conversion system is configured to receive hydrogen gas from the storage tanks and to convert the chemical energy of the hydrogen into mechanical or electric energy. A cooling arrangement is configured to cool the energy conversion system. A wall is provided behind the cab and laterally of the storage tanks, the wall having its main extension in a vertical plane, wherein said wall houses at least a part of said cooling arrangement.

A machine includes an engine compartment, an engine located within the engine compartment, a first compartment located on a first side of the machine, external to the engine compartment, and accessible via the engine compartment, as well as a second compartment located on a second side of the machine, external to the engine compartment, and accessible via the engine compartment. A first actuator is disposed on the first side of the machine and couples to a first linkage member that supports a work implement. A second actuator is disposed on the second side of the machine and couples to a second linkage member that supports the work implement. A first fuel tank is located in the first compartment, coplanar with the first actuator. A second fuel tank is located in the second compartment, coplanar with the second actuator.

A work machine, more particularly a wheeled loader, having a cab for the operator of the work machine, wherein the work machine has a drive which can be operated with hydrogen and that one or more tanks for receiving hydrogen are provided, wherein components for receiving the tanks are provided, wherein the tank or tanks are arranged below the cab and, when the work machine is viewed from above, next to the cab of the work machine, wherein the components for receiving the tanks do not have a direct mechanical connection to the cab, and that an armor is provided which partially or completely surrounds the tank.
