Abstract

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.
