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 working vehicle according to an embodiment includes an exhaust pipeline and a cover. The exhaust pipeline includes an exhaust gas purification device provided to stand on one of left and right sides of a running vehicle body. The cover is provided to cover at least a peripheral surface of the exhaust gas purification device of the exhaust pipeline and has an opening in a bottom thereof. The cover has a plurality of vent holes with a diameter less than that of the opening that are formed above the opening.

An all-terrain vehicle has an air ventilation system positioned adjacent a rearmost point of the front ground engaging members and directing air rearwardly through an engine compartment, wherein the air ventilation system includes at least one air scoop adjacent a front of the vehicle for directing the air. In addition, an ATV is disclosed having a rear rack having an integral storage bin, where the storage bin is one piece with the rear rack. The storage bin is sealed.

A working machine includes a vehicle body; a traveling device that supports the vehicle body; a drive that drives the traveling device; and a cabin that accommodates an operator seat. The drive has a drive motor that drives the traveling device; a fuel cell that supplies electric power to the drive motor; a controller that controls power supply from the fuel cell to the drive motor; and a hydrogen tank that supplies a hydrogen gas for fuel to the fuel cell. The hydrogen tank is disposed in an upper portion of an internal space of the cabin.

A vehicle body rear portion includes a vehicle body floor and a fuel tank. The vehicle body floor has a tire storage area that is hollowed downward. The fuel tank is supported by a lower surface of the vehicle body floor on a forward side of the tire storage area. A stiffener is attached to the vehicle body floor at a forward position of the tire storage area. The stiffener extends along a vehicle body forward/rearward direction and reinforces an upper region of the fuel tank of the vehicle body floor.

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.
