摘要:
A device for exhaust gas heat utilization in internal combustion engines of motor vehicles includes an exhaust gas line which in sections includes a first exhaust gas flow duct and a second exhaust gas flow duct connected in parallel. A valve flap is movable between a closed position and an open position, which can selectively close or at least partly clear a flow cross-section of the first or second exhaust gas flow duct. At least one thermoelectric generator module is thermally coupled with the second exhaust gas flow duct and with a cooling circuit. The device also includes an expansion material actuator for temperature-dependent actuation of the valve flap.

摘要:
A thermoelectric module (10) has a plurality of series-connected thermoelectric elements which are arranged between a first module housing plate defining a high-temperature side and a second module housing plate defining a low-temperature side, wherein laterally beside the thermoelectric elements and towards the end faces of the module housing plates at least one elastic compensating element is provided, which exerts a lateral holding force on the thermoelectric elements and extends from one inner side of the opposed module housing plates to the other. Such thermoelectric module (10) is contained in a thermoelectric generator unit (100), with a generator housing (102) in which at least one elastic compensating element (20) and at least one thermoelectric module (10) are accommodated, wherein the generator housing (102) exerts a pretension on the thermoelectric module (10) via the elastic compensating element (20).
摘要:
A machine tool for manufacturing exhaust gas cleaning devices, in particular diesel particulate filters and catalysts that have a housing and a gas-traversed insert clamped in the housing, comprises at least one tool, in which the insert is clamped in the housing. A heating device that heats the housing is integrated in the tool. In a method for manufacturing exhaust gas cleaning devices, the heated housing is plastically deformed in a machine tool, and the insert is inserted into the housing.

摘要:
An exhaust gas treatment device, in particular for an internal combustion engine, is fitted with a housing including an entrance and an exit. At least one porous substrate is accommodated in the housing and has an exhaust gas flowing through the substrate. The porous substrate is arranged in the flow path from the entrance to the exit. At least one thermoelectric generator is provided on the housing.
