Internal combustion engine operable with different cycling methods (e.g. two-stroke, four-stroke) has exhaust gas sound damper with different geometries matched to different cycle methods

The engine (1) has exhaust gas damping (6) with different geometries that can be changed by changeover elements depending on engine data. The engine can be operated with different cycling methods (e.g. two-stroke, four-stroke, six stroke or twelve stroke) and the different geometries of the damper a...

More Information
Summary:The engine (1) has exhaust gas damping (6) with different geometries that can be changed by changeover elements depending on engine data. The engine can be operated with different cycling methods (e.g. two-stroke, four-stroke, six stroke or twelve stroke) and the different geometries of the damper are matched to the different cycle methods. An Independent claim is also included for a method. Ein Abgasschalldämpfer, der unterschiedliche Geometrien aufweist, die durch Schaltorgane in Abhängigkeit von Motordaten schaltbar sind, ist einem Verbrennungsmotor zugeordnet. Die beim Betrieb mit unterschiedlichen Taktverfahren auftretenden Auspuffgeräusche werden dadurch unterdrückt, daß die unterschiedlichen Geometrien des Abgasschalldämpfers zumindest auf die unterschiedlichen Taktverfahren des Verbrennungsmotors abgestimmt sind.
