Patent number: 9188039Abstract: A device for exhaust-gas treatment near an engine includes an annular structure and a guide structure disposed in an exhaust line. An inner wall forms an inner flow passage and an outer flow passage in the annular structure. The inner wall and the guide structure form a gap in such a way that only a limited secondary flow of the exhaust gas is conducted through the inner flow passage. A motor vehicle having the device is also provided.Type: GrantFiled: January 28, 2013Date of Patent: November 17, 2015Assignees: EMITEC Gesellschaft fuer Emissionstechnologie mbH, J.

Patent number: 9163545Abstract: A heat exchanger (9), of e.g. an exhaust gas system (5) for an internal combustion engine (1), includes a thermoelectric generator (12) having a hot side (13) and a cold side (14) and including a heating tube (15) on a hot side of a heating device (10), and a cooling tube (16) on a cold side of a cooling device (11). The heating tube and the cooling tube are stacked on one another and form a tube stack (18), with the heating tube and the cooling tube extending parallel to one another in a longitudinal direction (19) of the tube stack. For energy efficiency, a housing (21) of the heat exchanger has a jacket (23) with an integral re-tensioning section (25) that is resiliently adjustable between a relaxed state and a tensioned state. The pre-tensioning section generates a pre-tensioning force (26) pressing the tube stack in a stacking direction (17).Type: GrantFiled: April 10, 2013Date of Patent: October 20, 2015Assignee: Eberspächer Exhaust Technology GmbH & Co.

Patent number: 9145802Abstract: A heat exchanger (7) for an exhaust system (5) of an internal combustion engine (1), includes a heating tube (16) for carrying hot exhaust gas and a cooling tube (17) for carrying a liquid cooling agent. A thermoelectric generator (13) generates an electric voltage from a temperature difference and is arranged with the adjacent tubes in a stacking direction (18) to form a stack (21). A support tube (28) is supported in the stacking direction on wall sections (29) of the respective tube (16, 17), which wall sections mutually face each other, and is arranged in the respective heating tube (16) and/or cooling tube (17). Increased energy efficiency is achieved if at least two support tubes (28), which differ from one another by tube length and/or tube end (30) and/or by tube cross sections, are arranged in the respective tube (16, 17) at right angles to a longitudinal direction (31).Type: GrantFiled: August 19, 2013Date of Patent: September 29, 2015Assignee: Eberspächer Exhaust Technology GmbH & Co.
