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 refuse vehicle has a tailgate. The tailgate has a framework to secure CNG tanks. A cover overlays the frame work to provide an aesthetic appearance to the vehicle.

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.

The present disclosure includes: a cowl member that is formed to extend in a vehicle width direction and bulges to the front from a rear side of a motor chamber; a power unit that is fixed to a right side frame in the motor chamber, has a lower portion fixed to a vehicle body, and drives the vehicle by electricity; and a protection bracket provided on an upper surface of the power unit, wherein the protection bracket is configured to abut the cowl member in the case where a frontal collision of a vehicle occurs and the power unit moves downward to the rear.

A multiple fuel tank purge system and method includes providing a pair of fuel tanks, including a main fuel tank for containing impure fuel and a separate, auxiliary fuel tank that contains commercial canned fuel. The engine runs on the impure fuel from the main fuel tank while the engine is in normal use, and then employs a shutdown cycle that switches to the commercial canned fuel from the auxiliary fuel tank for some pre-set time period. This arrangement allows the engine to be purged of the impure fuel (by burning the impure fuel during the shutdown cycle) and replaced by the commercial pre-mixed fuel before the engine is finally shut down. The system may further include a novel fuel cap with a fuel line, a tank within a tank fuel container, and/or an electronically actuated shutdown cycle mechanism.

A swivel working machine includes a swivel base, a prime mover installed in the swivel base, a working device provided at the swivel base, and a support mechanism that supports a fuel cylinder in a rotatable manner around a pivot shaft. The fuel cylinder contains fuel for the prime mover. The support mechanism includes a support rotating body that supports the fuel cylinder and that rotates around the pivot shaft, a rotational-position defining mechanism including a pin that defines a rotational position of the support rotating body around the pivot shaft, and an adjustment mechanism that adjusts a position of the pivot shaft relative to the pin.

A container, a stackable container assembly and a vehicle having a container. The container includes a container body having a top surface and a bottom surface; and a fixture assembly configured for receiving an accessory container, the fixture assembly being separately formed from and attached to the top surface, the bottom surface being configured for connecting the container to a vehicle, the bottom surface including: a tongue attached to the bottom surface, the tongue extending from the bottom surface, the tongue being configured for inserting into a first vehicle anchor fixture connected to the vehicle, and an anchor attached to the bottom surface, the anchor being configured for inserting into a second vehicle anchor fixture, the anchor including: at least one anchor lock extending parallel to the bottom surface.

A vehicle is provided with an interior chamber apart from a passenger compartment, and a container chamber in which a high pressure gas container is accommodated. A heat generating body is accommodated in the interior chamber. Further, in the vehicle, there are formed introduction ports through which atmospheric air is introduced into the interior chamber, a communication passage that enables communication between the interior chamber and the container chamber, and a lead-out port through which the atmospheric air is led out from the container chamber. The atmospheric air that is introduced into the interior chamber through the introduction ports flows into the container chamber via the communication passage, and furthermore, is led out to the exterior of the container chamber from the lead-out port.

To ease work of transferring a fuel from a fuel supply tank to a fuel tank, a fuel supply guide to be used to supply the fuel by using the fuel supply tank to the fuel tank having a tank body for storing the fuel and a fuel supply port on the upper side of the tank body includes a support member provided on an upper portion of the fuel tank, and a body member projecting from the support member in a direction away from the fuel supply port as the body member extends upward and projecting higher than the fuel supply port. The body member is capable of receiving the fuel supply tank by an upper portion thereof to support the fuel supply tank.

An apparatus and a method are provided for an alternative fuel system, comprising a plurality of fuel tank assemblies interconnected with fuel lines; the plurality of fuel tank assemblies comprising a CNG fuel tank and a fuel tank shield; wherein a first and second fuel tank assembly is disposed immediately in front of a rear wheel assembly, and a third fuel tank assembly is disposed immediately behind the rear wheel assembly.
