Abstract
An energy recovery system includes a main line capable of carrying the exhaust gases of an engine, at least a first and a second thermoelectric devices capable of producing electricity by Seebeck effect, the second thermoelectric device being located downstream from the first thermoelectric device, the thermoelectric devices each having an optimum temperature range and a highest admissible temperature. The optimum temperature range and the highest admissible temperature of the second thermoelectric device are lower than the optimum temperature range and the highest admissible temperature of the first thermoelectric device, respectively. The system further includes a controller for controlling the flow rate of the exhaust gases passing against the second thermoelectric device, in order to prevent the second thermoelectric device from being exposed to temperatures exceeding its highest admissible temperature.
