Abstract
A method for operating a system having a plurality of internal combustion engines coupled together such that then outputs are drawn off by a common load, a downstream individual exhaust gas aftertreatment device, in which the exhaust gas of a particular engine undergoes an individual exhaust gas aftertreatment, positioned downstream of each engine, or a common exhaust gas aftertreatment device, in which the exhaust gas undergoes a common exhaust gas aftertreatment, positioned downstream of to the engine. To regenerate an exhaust gas aftertreatment device, the drive output of one engine is reduced, the temperature of the exhaust gas is increased, and the drive output of a second engine is increased such that the drive output reduction is at least partially compensated for.
