Abstract: The invention relates to a tibial component (1) of a knee endoprosthesis for anchoring on the proximal tibia, comprising a tibial plateau (2), a tibial shaft (3) on the underside of the tibial plateau (2) facing the tibia, and having a liner (4) for receiving and supporting the lateral condyle surface of a femoral part. To allow different heights and shapes of the liner to be provided medially and laterally, and to ensure that just one individual liner can be exchanged in the event of revision and, for this purpose, a minimally invasive intervention (operation) is sufficient, it is suggested according to the invention that the tibial component (1) has one liner or preferably two liners (4a, 4b) embodied as individual parts, which liner or liners is/are exchangeably anchored on the tibial component (1).

Abstract: An exhaust gas routing device for an internal-combustion engine having a thermoelectric generator is fluidically connected with an exhaust gas line and a pipe guiding a coolant. The generator has a plurality of thermoelectric yoke pairs which are arranged between a first surface heated by the exhaust gas and a second surface cooled by the coolant. The exhaust gas routing device has a device guiding the exhaust gas along the first surface at a flow velocity that increases in the flow direction of the exhaust gas.
