Research on characteristics of thermoelectric generator with integrated muffler and catalytic converter

Automobile exhaust contains a large amount of heat loss, which has a high potential for energy saving. In order to recover the heat in the exhaust gas and improve the compatibility of thermoelectric generator (TEG), muffler and catalytic converter, an integrated automobile exhaust thermoelectric gen...
