  • Device for treatment of exhaust of an internal combustion engine
    Patent number: 7449162
    Abstract: A method and a device for treatment of the exhaust of an internal combustion engine in which a fluid is used as an auxiliary agent for the treatment; a partial chemical conversion of the auxiliary agent is at least occasionally stimulated in order to produce a substance that reduces the freezing point of the fluid when the temperature of the fluid falls below a critical value.

  • Device for exhaust gas treatment of a combustion system
    Patent number: 7100367
    Abstract: A device is provided for the exhaust gas treatment of a combustion system, e.g., a diesel combustion system. The device has a first storage unit for storing at least one urea-water solution, and an exhaust gas treatment is implemented without great expenditure. According to the present invention, this result is achieved by the urea-water solution including at least one additive for chemically influencing the urea-water solution.

  • Device for cleaning gas mixtures and method for its manufacture
    Publication number: 20050279062
    Abstract: A filter device and a method for cleaning gas mixtures containing particles, e.g., soot-containing exhaust gases of internal combustion engines, as well as a method for the manufacture of the filter device, are provided. The filter device has a porous surface made of a filter base material exposed to the gas mixture to be cleaned. A layer of ceramic fibers is applied onto the surface exposed to the gas mixture to be cleaned.
