ABSTRACT:
An automobile catalytic converter that utilizes the energy of the exothermic reactions that take place in the catalysis substrate to produce electrical energy with a thermoelectric generator. On vehicle cold start, the thermoelectric generator is used as a heat pump to heat the catalyst substrate to reduce the time to catalyst light-off. In this way, the catalytic converter comes up to operating temperature more rapidly, reducing the amount of pollutant emissions at vehicle start-up.
