A device for the aftertreatment of exhaust gases in an exhaust gas system of internal combustion engines, having at least one reductant decomposition catalyst. Arranged in the exhaust gas flow, and a metering device arranged upstream of the latter in an exhaust gas line for supplying reductant. Preferably at least one other catalyst device is provided downstream of the reductant decomposition catalyst. An inlet section for the exhaust gas having at least one flow deflection area is arranged upstream of the reductant decomposition catalyst and constructed for the exhaust gas to be fed into a housing radially outside an inlet pipe adjoining the reductant decomposition catalyst that encloses the inlet pipe, and is guided in counterflow through a front inlet opening of the inlet pipe to the reductant decomposition catalyst. The reductant is fed into the flow deflection area associated with the inlet opening.

Device for the aftertreatment of exhaust gases of internal combustion engines

The invention is directed to a device for converting exhaust gas constituents of an internal combustion engine by means of at least one catalyzer and/or particle filter and/or particle separator and for compensating relative movements between the internal combustion engine and the exhaust gas train and/or relative movements between different parts of the exhaust gas train by means of at least one compensator permitting relative movements. The at least one catalyzer for converting exhaust gas constituents and/or the at least one particle filter and/or the at least one particle separator are/is arranged inside the compensator and or inside the part of the exhaust gas train that is permanently connected to the compensator. The outer diameter of the catalyzer and/or of the particle filter and/or of the particle separator is less than or equal to the inner diameter of the compensator.

Compact exhaust gas aftertreatment system

The invention relates to an apparatus for floor cleaning, with several wheels being attached to a frame R in such a way that a curve movement about a momentary center MP, MP MP can be performed and all momentary centers MP, MP MP form a momentary center axis MA extending substantially transversally to the frame R, and with a cleaning device  being received in the frame R, which cleaning device forms a cleaning surface area RF which is delimited by a circumferential edge. In order to reduce uncleaned residual surfaces when moving along contours it is provided in accordance with the invention that the momentary center axis MA forms at least one point of intersection S S in a section of the circumferential edge disposed in the zone of the longitudinal side of the frame R.
