ABSTRACT:
The two cylinder groups of an internal-combustion engine each have a separate exhaust gas catalyst. When one of these cylinder groups is shut off by preventing the supply of fuel, it is possible that the assigned exhaust gas catalyst may be cooled below its operating temperature. In order to avoid this, the whole exhaust gas system is constructed in such a manner that the gases emitted from the shut-off cylinder group are heated by the exhaust gases of the continuously fired cylinder group.
