ABSTRACT:
An exhaust gas purifier arrangement for an internal combustion engine includes a gas adsorber and a catalyzer located downstream from the adsorber in the direction of exhaust gas flow and a burner providing hot burner gases to heat the catalyzer through a burner pipe which traverses the adsorber, and also includes an arrangement for controlling the heat transfer between the burner pipe and the gas adsorber so that heating the adsorber to its desorption temperature is accelerated at low ambient temperatures.
