The method and a device provide a reducing agent-containing gas flow in a quantity being easily controllable and adaptable to dynamic changes especially in exhaust systems of mobile applications such as automobiles. A temperature of a first zone is kept at 150° C. or just below while a temperature of a second zone is kept at more than 300° C.

    摘要： A device for evaporating at least one of the following reactants: a reducing agent precursor solution and a reducing agent precursor, includes at least one electrically heatable heating zone having at least one electrically operable heating element with a heating resistor that is self-regulated about a significant temperature. A method and the device for evaporating a reactant allow a simple control of an evaporation process, especially of a urea/water solution, to provide a reducing agent, especially in an SCR process. The heating resistors have a significant temperature that corresponds to a control temperature of the heating resistor. The need for additional control electronics can be removed by adjusting a correspondingly steep curve within a range.

    摘要： A device and method for providing a gaseous substance mixture which includes at least one reducing agent and/or at least one reducing agent precursor, includes a reservoir for an aqueous solution which includes at least one reducing agent precursor that can be flow connected to an evaporator chamber, and a device for dosing the aqueous solution in the evaporator chamber. A device can heat the evaporator chamber to a temperature higher than or equal to a critical temperature, in which the aqueous solution is at least partially evaporated. The device and method enable reducing agent to be provided for selective catalytic reduction of nitrogen oxides in the exhaust of an internal combustion engine. Preferably, an evaporator unit is configured as the evaporator chamber and a hydrolysis catalytic converter is disposed outside the exhaust system. As a result, the size of the hydrolysis catalytic converter is reduced, allowing compact construction.

    摘要： A method for removing particulates from a gas stream includes providing a gas-permeable filter layer having subregions with a parameter of differing magnitudes in the direction of the layer thickness. This parameter relates at least to the porosity, the fiber diameter of fibers or the fiber type content of the filter layer. The gas stream is divided into partial gas streams which are each passed through different subregions of the filter layer. Fiber layers, particulate filters, exhaust systems and vehicles based on this method are also provided.

    摘要： A device and a method for providing a gaseous substance mixture including at least one of a reducing agent and/or a reducing agent precursor, include a reservoir for an aqueous solution including at least one reducing agent precursor, from which the aqueous solution can be delivered into at least one metering line having a dispensing opening by a delivery device, and a device for heating the metering line above a critical temperature greater than the boiling temperature of water. Complete evaporation of an aqueous solution including urea and subsequent hydrolysis to form a substance mixture including ammonia, are carried out. The substance mixture is metered as a reducing agent into an SCR catalytic converter. Carrying out the evaporation outside the exhaust system uses considerably smaller hydrolysis catalytic converters, which is space-saving and cost-saving compared to conventional devices for providing a reducing agent for selective catalytic reduction of nitrogen oxides.
