ABSTRACT:
An installation for the catalytic afterburning of exhaust gases in the exhaust gas system of an internal combustion engine, which is equipped with a by-pass line by-passing the installation for the catalytic afterburning, whereby a throttle valve actuated in dependence on the temperature of the installation for the catalytic afterburning is arranged in the by-pass line; to prevent the throttle valve from getting stuck due to rusting, the throttle valve is actuated also independently of the temperature of the installation for the catalytic afterburning, in dependence on at least one parameter of the internal combustion engine.
