    摘要: According to a current operating state (BZ) of an internal combustion engine and/or a specified particle number emission limit (PE), a minimum hydrocarbon concentration (HCMK) of a combustion chamber exhaust gas of the internal combustion engine that is required to comply with the specified particle number emission limit is determined. An operation (B) of the internal combustion engine is specified to achieve a hydrocarbon concentration (HCK) of the combustion chamber exhaust gas that is at least as large as the determined minimum hydrocarbon concentration (HCMK).

    摘要: A honeycomb body for an exhaust-gas purification system may be used, for example, as a carrier body for catalytically acting coatings or as a filter, absorber or mixer in the exhaust system of an internal combustion engine. The honeycomb body has channels, an axial main direction, a planar front surface, a planar end surface and a circumferential surface disposed parallel to the axial main direction. The front surface and/or the end surface are disposed obliquely with respect to the axial main direction. Such a honeycomb body is advantageous, in particular, for applying reducing agent to the oblique end or front surface. A method for producing a honeycomb body, an exhaust line section and a motor vehicle are also provided.

    摘要: A method for regenerating an open particle separator includes at least determining at least one parameter, as a characteristic variable of a regeneration capability of the open particle separator. The at least one parameter is compared with a first threshold value. At least one portion of a comparison period during which the parameter has reached the first threshold value is determined. The portion is compared with a first minimum portion corresponding to a minimum regeneration time in the comparison time period. Measures are initiated to influence the parameter so that the parameter lies at least according to the first minimum portion and the first threshold value is reached and/or the open particle separator is regenerated. A motor vehicle having at least one open particle separator is also provided.

    摘要: A device includes an electrically heatable honeycomb body, particularly for treating an exhaust gas flow of a mobile internal combustion machine. The device includes sheet metal foils forming channels and being in electrical contact with a housing. The housing has a terminal for connection to a voltage source, a plurality of contact points disposed remotely from the terminal for contacting the sheet metal foils and a respective contact conductor between the terminal and each contact point. The contact conductors have the same electrical resistance. A motor vehicle having at least one such device is 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.
