Abstract
A thermoelectric generating device has a thermoelectric element which utilizes an exhaust gas from an engine as a high temperature heat source and an engine coolant as a low temperature heat source in order to generate electricity. An introducing passage introduces a part of the exhaust gas passed through the thermoelectric element into an intake of the engine. An introducing valve opens and closes the introducing passage. A controller controls an opening degree of the introducing valve according to a load of the engine.
