Abstract

An operating method for a device that has an internal combustion engine having a crankshaft and a plurality of cylinders and an exhaust gas aftertreatment system. The operating method is distinguished, in particular, by the fact that fuel injection into at least one of the cylinders is shut down when required and the at least one shut-down cylinder is put into a braking mode, with the result that the temperature of the exhaust gas for the exhaust gas aftertreatment system can be increased.
