摘要： An evaporation unit for evaporating an aqueous solution including at least one reducing agent precursor, includes at least one evaporator cavity defined by a wall made of a material containing titanium. A heat-imparting layer disposed outside the evaporator cavity is made of a material having a thermal conductivity of at least 100 W/mK (Watts per meter and Kelvin) and is connected to the evaporator cavity in a heat-conducting manner. A heating layer disposed outside the heat-imparting layer is connected in a materially integral manner to the heat-imparting layer. The evaporator unit can be controlled in a highly dynamic manner, thereby enabling a sufficiently high amount of ammonia to be produced even during rapid load changes and consequently significant increases in the concentration of nitric oxide in the exhaust gas of the internal combustion engine. A device and a motor vehicle having the evaporation unit are also provided.

摘要： An apparatus for treating exhaust gas of an internal combustion engine, includes a feed conduit feeding aqueous solution, a hydrolysis catalytic converter connected to the feed conduit and an SCR catalytic converter through which exhaust gas flows. A rod-shaped heating element heats at least parts of the feed conduit and/or hydrolysis catalytic converter. The apparatus provides a compact structure of a feed conduit heated by a rod-shaped element and a corresponding hydrolysis catalytic converter, with which an aqueous solution containing urea can be evaporated and then hydrolyzed to a gas stream containing ammonia. This gas stream serves as a reducing agent in the SCR process. The compact configuration allows installation in very confined space conditions. The hydrolysis catalytic converter, through which exhaust gas does not flow, permits the volume of the hydrolysis catalytic converter to be decisively reduced, since significantly smaller mass flows of gas need to be hydrolyzed therein.

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 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.
