摘要： A casing tube is provided for a honeycomb element used for exhaust gas treatment. The casing tube is provided with a first area which is located close to a first front face and a third area which is located to close a second front face. The casing tube has a first inner diameter in the first and third area and is provided with a second area that is disposed between the first and the third area. The second area has a second inner diameter that is larger than the first inner diameter. The casing tube is characterized in that the axial length of the first area is less than 5 mm, preferably less than 3 mm. The relatively narrow first area enables the honeycomb to be permanently fixed and ensures that only a small amount of heat is transmitted to the casing tube. As a result, a significant improvement is achieved in the cold start performance of a catalytic converter.

摘要： A method positions a sensor in a honeycomb body which is provided with hollow spaces that can be penetrated at least in part by an exhaust gas. The sensor is placed in an area of the honeycomb body in which at least one minimum hydrogen concentration occurs when the honeycomb body is operated in the emission system of a motor vehicle. The sensor positioning method allows the sensor to be placed in the honeycomb body in such a way that systematic errors that occur are kept as small as possible as a result of an inherent transverse sensitivity of the sensor to hydrogen. This applies especially to lambda probes. A honeycomb body contains the sensor which is placed so as to supply particularly reliable test data whose systematic error is as small as possible.

摘要： A device for adsorbing at least one component of an exhaust gas, in particular in an exhaust system of an internal-combustion engine of a vehicle, includes an adsorber having a volume through which an exhaust gas can flow at a temperature and a mass flow rate. The volume corresponds to the following equation: V ≤ a + b · t + c m + d · t 2 + e m 2 + f · t m + g · t 3 + h m 3 + i · t m 2 + k · t 2 m , where V=volume of the adsorber [l], t=mean temperature of the exhaust gas [° C.], and m=mean mass flow rate of the exhaust gas [kg/h]. An adsorber with such a volume has a particularly compact structure, as a function of properties of the exhaust gas flowing through it and thus, for example, improves a cold-start performance of a downstream catalytic converter.

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.
