ABSTRACT:
An exhaust emission control system.A generator has a thermoelectric conversion element for achieving thermoelectric conversion by making use of heat of exhaust gas. An exhaust purifying catalyst disposed in the generator or on the exhaust downstream side of the generator, and a heat conduction varying device make heat conduction from the exhaust gas to the thermoelectric conversion element variable between a high conduction state and a low conduction state. When a temperature of the exhaust purifying catalyst is higher than a predetermined temperature, the heat conduction varying device varies the heat conduction from the exhaust gas to the thermoelectric conversion element into the high conduction state. This permits the system to efficiently re-collect thermal energy from the exhaust gas and convert it into electric energy, without increase in a time to arrival of the exhaust purifying catalyst at an activation temperature thereof.
