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： A foil for producing a metal honeycomb or catalyst carrier body, has an average surface roughness of more than 0.3 μm (micrometers) on both surfaces in at least one measurement direction. Preferably, the foil is rolled and has an average surface roughness of more than 0.3 or 0.5 μm, especially approximately 0.6 μm, in the rolling direction and/or transverse thereto. The foil can have an oxide coating with a thickness between 60 and 80 or between 70 and 75 nm (nanometers) on both surfaces. Despite the roughness, an even thickness of the oxide coating with a tolerance of less than 10% or 5% is advantageous on both surfaces. The foil allows production of durable honeycomb bodies, especially for exhaust systems of internal combustion engines, requiring an exactly defined distribution and quality of compounds in the interior thereof. A honeycomb body and method of production using a foil, are also provided.

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.
