  • Patent number: 8365526
    Abstract: A vehicle or stationary power plant having an internal combustion engine as a drive source and having components adapted to be supplied with heat from a medium accommodated in a closed loop The turbine of the exhaust gas turbocharger provided for turbocharging the internal combustion engine acts as a heat source. A heat exchanger is disposed externally on the turbine housing and can be incorporated or switchable into the medium loop The medium can be conveyed directly or channeled through the interior of the heat exchanger, and the medium is adapted to be heated up in such interior utilizing at least thermal radiation energy from the hot turbine housing.
    Type: Grant

  • Patent number: 7294313
    Abstract: A device for producing ammonia from urea pellets includes a pellet dispensing device, a pellet accelerator, a pellet shooting channel, and an ammonia reactor having a chamber or zone for shooting in urea pellets and a pellet deflector arranged on an end of the shooting path. The device further includes a urea pellet evaporation device and a hydrolytic catalytic converter. The urea pellets are removed from the reservoir in a regulated number/quantity by a dispensing device and transported to the accelerating device, where the pellets are moved from the pellet shooting channel into the ammonia reactor, where they are broken down into small pieces by impacting a pellet deflector at the end of the shooting path. The pieces are converted into a gas mixture containing ammonia and isocyanic acid by means of a urea evaporation device. The isocyanic acid is subsequently converted into ammonia and carbon dioxide.

  • Patent number: 7017336
    Abstract: A motor vehicle having an internal combustion engine, which is adapted to be supplied with fuel from a fuel tank, is provided. A preliminary muffler and a main muffler are disposed in an exhaust gas section of the engine. A hydrolysis catalytic converter and optionally at least one oxidation catalytic converter are disposed in the preliminary muffler. A dosing mechanism supplies a urea-water solution to the hydrolysis catalytic converter from a UWS tank. A structural unit is provided that is comprised of a fuel tank, the UWS tank, and the preliminary muffler, with the structural unit being adapted to be secured in its entirety to the chassis frame of the vehicle.
