  • Patent number: 10184613
    Abstract: A system for filling an LPG vehicle with LPG using an auxiliary bombe is provided. The system may be configured for easily filling a main bombe with LPG even in the hot season (summertime) or the like during which the outside temperature rapidly rises, by using an auxiliary bombe in addition to using the main bombe. The system may also be capable of always smoothly refilling the main bombe with LPG by moving a portion of the LPG in the main bombe to the auxiliary bombe, when the pressure in the main bombe is higher than the LPG filling pressure of a filling gun in the hot season during which the outside temperature rapidly rises, so that the pressure in the main bombe becomes lower than the filling pressure.

  • Patent number: 7398841
    Abstract: An energy conversion apparatus and method using recovered energy sources including motor vehicle kinetic energy (deceleration and shock) and wind resistance, supplemented by liquefied air transferred to the vehicle and by solar radiation thereto. The energy sources are combined, as available, to drive a compressor for supplying intake working fluid of a motor vehicle prime mover, wherein liquefied air provides pre-compression cooling of an atmospheric air portion of the working fluid. The liquefied air is made by recovered energy, stored and transferred between vehicles and between vehicles and stationary sites. In a hybrid version of the vehicle, exhaust heat from a combustion engine part of the prime mover increases working fluid temperature in a gas expander part, thereof; the engine and expander operating independently or together for improved vehicle propulsion efficiency.

  • Patent number: 6527075
    Abstract: A vehicle includes a storage pack for storing gas under pressure for providing an onboard supply of the pressurized gas. The pressurized gas may be used as a medicinal gas, e.g. oxygen, on emergency medical vehicles, or the gas may be used as a fuel source for a motorized vehicle having a motor that runs on combustible gas. The gas storage pack includes a pressure vessel formed from a plurality of hollow chambers, which have either an ellipsoidal or spherical shape, interconnected by a plurality of relatively narrow conduit sections disposed between consecutive ones of the chambers. The pressure vessel includes a reinforcing filament wrapped around the interconnected chambers and interconnecting conduit sections to limit radial expansion of the chambers and conduit sections when filled with a fluid under pressure. The gas storage pack further includes a gas transfer control system attached to the pressure vessel for controlling gas flow into and out of the pressure vessel.

  • Patent number: 6481751
    Abstract: A compressed natural gas fuel tank for vehicles employing internal combustion engines. A fuel tank of heavy gauge metal is interposed within the vehicle frame as an integral portion thereof. Overlay channel members are welded or otherwise affixed to the tank and then welded or otherwise affixed to the side rails or channel members of the vehicle frame. The tank, of heavy gauge metal and non-circular cross section, is also welded or otherwise appropriately affixed to the vehicle floor. The tank is capable of receiving natural gas at high pressure levels, while also serving structurally as a frame element, providing continuity of the side rail members of the frame, while also serving to further interconnect the vehicle floor with the side rails. Also presented are tank assemblies in which a tank housing receives a plurality of cylindrical pressure tanks of composite material construction. The cylindrical tanks are nested within the tank housing, which also serves as an integral part of the vehicle frame.

  • Patent number: 6439334
    Abstract: A gaseous alternative fuels vehicle has a vehicle body with an engine and a gas fuel tank. A gaseous fuel supply system establishes gas communication between the engine and the gas fuel tank. The gaseous fuel supply system includes a valve having a valve body with a housing having a first unvalved port and a second unvalved port. A through-flow channel extends between the first unvalved port and the second unvalved port. The through-flow channel provides continuous gaseous communication between the first unvalved port and the second unvalved port. A valved port is in gaseous communication with the gas fuel tank, and a valving channel extends between the valved port and the through-flow channel. The valving channel provides valved gaseous communication between the valved port and the through-flow channel. A flow controller has a valve element within the valving channel at a valve location.

  • Patent number: 6412588
    Abstract: A CNG fuel supply system is provided for mounting a plurality of Type 4 tanks on the roof of a bus. A manifold line extends to the roof of the bus and is anchored against movement relative to the length of the bus. A shutoff valve is associated with each tank, the shutoff valve being mounted on an end of its respective tank adjacent the manifold line. The shutoff valve has two ports which communicate with the tank when the shutoff valve is open. An inlet tubing piece connects the manifold line to one of the two ports of each tank and an outlet tubing piece connects the manifold line to the other port of each tank. The tubing pieces are manufactured to be substantially identical to other tubing pieces of the tank system for a given bus, and to other tubing pieces for other buses in the fleet, thus reducing the number of different tubing pieces utilized for construction and maintenance of the fleet.
