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.

Exhaust gas purificating arrangement for an internal combustion engine

A catalytic converter for use in the exhaust line of an internal combustion engine wherein the catalytically active noble metal coating is deposited only on the rearward portion of the inert carrier, with respect to the direction of flow of the exhaust gases, said inert carrier being fully coated with a washcoat capable of absorbing catalyst poisons before application of the catalytically active noble metal coating.
