EVAPORATION UNIT FOR PRODUCING A GAS INCLUDING AT LEAST ONE REDUCING AGENT PRECURSOR AND/OR A REDUCING AGENT AND DEVICE AND MOTOR VEHICLE HAVING THE EVAPORATION UNIT
First Claim
1. An evaporation unit for the evaporation of an aqueous solution including at least one reducing agent precursor, the evaporation unit comprising:
- a wall made of a material including titanium, said wall delimiting at least one evaporator cavity;
a heat-imparting layer made of a material with a thermal conductivity of at least 100 W/mK (Watts per meter and Kelvin), said heat-imparting layer lying outside said evaporator cavity and being thermally conductively connected to said evaporator cavity; and
a heating layer disposed outside of said heat-imparting layer and being materially integrally connected to said heat-imparting layer.

Abstract
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.
