Abstract
Methods and apparatus for removing undesired pollutants from exhausts streams of spark-ignited internal-combustion engines in vehicles while producing electrical energy as a byproduct. The apparatus includes a reduction catalyst, a thermoelectric generator (TEG), and an oxidation catalyst. The TEG cools the exhaust stream and generates electricity. The exhaust stream is oxygenated after passing through the TEG and prior to passing through the oxidation catalyst.
