Abstract
An assembly and method for reducing nitrogen oxides, carbon monoxide, hydrocarbons and hydrogen gas in exhausts of internal combustion engines and simultaneously generating electrical power, wherein the exhaust is acted upon in a first stage catalytic converter and is at least in part passed through a thermoelectric generator for production of electrical power. The exhausts are thereafter directed to a second stage catalytic converter.
