Abstract: Exhaust systems of a combustion engine of a motor vehicle, motor vehicles with exhaust systems, and methods for operating an exhaust system of a combustion engine in a motor vehicle are provided. An exhaust system includes an exhaust line comprising a heat exchanger branch and a bypass branch. The exhaust line has an adjustable control element by which combustion gas flowing through the exhaust line is fed to the heat exchanger branch and/or the bypass branch. A heat exchanger is connected to the heat exchanger branch and to a cooling circuit and an adjusting mechanism has an actuator for adjustment of the adjusting mechanism. The adjusting member of the adjusting mechanism is configured such that the actuator is spaced from the exhaust line.

Abstract: A muffler assembly for a vehicle includes a housing at least partially defining an internal cavity and having an inlet and an outlet. The muffler assembly includes an outlet pipe that has an inlet end open to the internal cavity and an outlet end open at the outlet of the housing. A siphon tube is in the internal cavity and has an inlet opening adjacent an inner surface of the housing and an outlet opening in fluid communication with the outlet pipe between the inlet end and the outlet end of the outlet pipe. The siphon tube is configured to remove condensate from the internal cavity when a predetermined pressure differential is established between the inlet opening and the outlet opening.

Abstract: A method is provided for ascertaining the setting of an exhaust gas flap, which is situated so it is adjustable in an exhaust system of a motor vehicle, by which a combustion gas flowing through an exhaust tract can alternately be supplied to a heat exchanger branch and/or a bypass branch, a pressure prevailing in the heat exchanger branch and/or in the bypass branch being measured to ascertain the setting of the exhaust gas flap, and a current position of the exhaust gas flap being ascertained by a comparison of the measured pressure to a reference value.
