A fuel system is provided that includes a mounting block assembly configured to support an end of a fuel tank. The end of the fuel tank has a boss. The mounting block assembly encloses a space configured to receive the boss of the fuel tank. The fuel system also includes a bearing disposed in the space. The bearing has a support surface configured for sliding support of the boss of the fuel tank at an interface between the first portion and the second portion of the mounting block assembly. The mounting block assembly has a debris mitigation structure, such as one or more of a wiper disposed in the bearing adjacent to the support surface, an endcap configured to be mounted around the boss, and a cover configured to at least partially enclose a span of a boss between an enclosed space of the fuel tank and an inboard side of the mounting block assembly.

A reinforcing element (10) for a motor vehicle body (1) comprising protection means (30, 31, 40, 41, 42) for protection against an impact at the rear of the vehicle, characterised in that it comprises at least two tubes (20, 22) to be positioned, generally, in the length direction of the vehicle, and a rigid contact surface (30, 31, 70) turned towards the rear, the rigid contact surface (30, 31, 70) and the two tubes (20, 22) being arranged with respect to each other in order to allow the vehicle to move in case of an impact at the rear.

This disclosure describes an assembly for gas (e.g., compressed natural gas) storage. The assembly includes multiple gas storage tanks, with each tank coupled to a separate sub-assembly that includes a pressure gauge, shutoff valve, and pressure relief device (PRD), providing for independent pressure monitoring, shutoff, and pressure relief for each of the tanks.

A gas sensor includes a gas detecting element that includes a first electrode, a metal oxide layer, and a second electrode; and a first insulating film that has an opening allowing the second electrode to be partially exposed therethrough and covers the first electrode, the metal oxide layer, and another part of the second electrode. The metal oxide layer has a characteristic where its resistance value changes as the second electrode makes contact with gas molecules including hydrogen atoms. A first step is provided at a portion lying on an interface between the metal oxide layer and the second electrode and located within the opening as viewed in plan view. A local region is provided in the metal oxide layer and near the first step. A degree of oxygen deficiency of the local region is greater than a degree of oxygen deficiency of other regions in the metal oxide layer.

A volume tank that houses a material is provided. The volume tank can include a first bulk head, a second bulk head opposite the first bulk head, a non-symmetrical frustoconical shell section, a cylindrical shell section and a transition section in between the non-symmetrical frustoconical shell section and the cylindrical shell section. The volume tank is configured to be coupled to a portion of a frame of a vehicle, and in a non-limiting embodiment, to a school bus.

Methods and systems are provided for protective cover. In one example, the protective cover may be configured to protect a fuel delivery module and may include a domed cap. The domed cap may resistant forces exerted on the protective cover and maintain clearance between the domed cap and enclosed electronic ports of the fuel delivery module.

A compressed natural gas fueling system includes a frame arrangement with at least one tank disposed therein and an inlet that can receive a compressed natural gas fueling nozzle to fill the at least one tank. The fueling system can be attached with and supported by frame rails behind a cabin of a vehicle such that the inlet is positioned above the frame rails.

An over the wheel well tank for storing liquid in a bed of a truck includes a tank body having a main tank portion shaped to fit in an area adjacent a wheel well in the bed of a truck and an over a wheel well tank portion shaped to fit in an area above a wheel well in the bed of a truck. The main tank portion is shaped to fit in an area adjacent a proximal side of the wheel well or in an area adjacent a distal side of the wheel well. The storage tank may further include a pumping system to pump liquid from within the storage tank to a location external to the storage tank.

A fuel system for a vehicle includes a fuel tank configured to provide fuel to an engine of the vehicle, a shutoff valve configured to selectively restrict a flow of the fuel along a flow path between the fuel tank and the engine, a temperature sensor configured to monitor a temperature of at least one of the engine of the vehicle or a temperature associated with a body area of the vehicle and provide a temperature signal, and a controller coupled to the temperature sensor and the shutoff valve. The controller is configured to control the shutoff valve to restrict the flow of the fuel in response to the temperature signal indicating a temperature in excess of a temperature threshold.

An auxiliary fueling system for filling fuel tanks disposed on a trailer is provided, which includes a fuel cell, a mounting apparatus mounted to a tractor hooked to the trailer for supporting the fuel cell thereon, and a fuel line for connecting the fuel cell to the fuel tanks on the trailer.
