ABSTRACT:
More particularly for the catalytic treatment of the exhaust gas of an IC engine, such as the IC engine of a motor vehicle, in the case of which the gases of combustion flow through a converter, the latter is provided with an emission buffer designed for the cold start state. It is capable of storing noxious emissions, more particularly those produced during a cold start, such as unburned hydrocarbons and to release them into the exhaust gas again.
