INTERNAL MOTOR HEATING OPERATION BY INCREASING LOAD

The invention relates to an operating method for a device comprising an internal combustion engine with a crankshaft and multiple cylinders and an exhaust aftertreatment system. The operating method is characterized in particular by the fact that, depending on demand, fuel injection into at least one of the cylinders (Z) is shut off (S1) and the at least one shut-off cylinder (Z) is placed in a braking operation (S2), so that in particular the temperature of the exhaust gas for the exhaust aftertreatment system can be increased.
