Abstract: A thermoelectric generator has a module chamber defined between an exhaust pipe portion and a coolant pipe. A thermoelectric conversion module and an HC sensor are located in the module chamber. An ECU performs a fault diagnosis on the thermoelectric generator by detecting the leakage of exhaust gas into the module chamber from the exhaust pipe portion based on detection information output by the HC sensor.

Abstract: A thermoelectric generator includes a structure, thermoelectric devices, a hollow port member, electric wires, a shielding member, and a cooling unit. The structure defines an enclosed space between a high-temperature medium and a low-temperature medium, and the enclosed space is in a low-oxygen condition. The thermoelectric devices are placed in the enclosed space. The port member has one end portion to which the structure is connected so that the port member communicates with the enclosed space, and the port member has an opening in the other end portion thereof. The electric wires are inserted through the port member, and each wire has one end portion connected to the thermoelectric devices, and the other end portion pulled out to the outside of the port member through the opening. The shielding member is fitted in the port member, and the electric wires pass through the shielding member. The cooling unit is configured to cool the shielding member.

Abstract: A thermoelectric generator for mounting on an internal combustion engine, includes a selecting device, an exhaust pipe, a thermoelectric conversion module, a regulating valve and a controller. The selecting device is configured to select a first operation mode and a second operation mode. The exhaust pipe includes a first exhaust passage and a second exhaust passage. The regulating valve configured to adjust a flow rate of the exhaust gas. The controller is configured to adjust an opening degree of the regulating valve such that the flow rate of the exhaust gas flowing through the second exhaust passage reduces as compared to that in the first operation mode, on the condition that the second operation mode is selected by the selecting device after completion of warm-up of the internal combustion engine.

Abstract: A thermoelectric generator that generates electricity using heat energy of exhaust gas, the thermoelectric generator comprising: an inflow portion into which exhaust gas flows from an exhaust passage; an outflow portion out of which exhaust gas flows; a branch passage that carries exhaust gas that has flowed in from the inflow portion toward the outflow portion; a plurality of thermoelectric modules arranged inside the branch passage, a length direction of each thermoelectric module of the plurality of thermoelectric modules being the same direction as a flow direction of exhaust gas in the exhaust passage, the plurality of thermoelectric modules being arranged in series in an exhaust gas flow direction from the inflow portion toward the outflow portion; and at least one wall that defines the branch passage, and the at least one wall being such that exhaust gas flows along both sides of the at least one wall.
