ABSTRACT:
The exhaust system of an internal combustion engine which includes one or several, sequential catalytic reactors is provided with a bypass channel through which some portion of the exhaust gases may be diverted. This diversion takes place whenever the gas flow rate becomes so high that the operating temperatures of one or more of the reactors would be exceeded. The gases flowing through the bypass channel are cooled prior to their reintroduction into the main exhaust pipe channel. The diversion of part of the gas stream into the bypass channel is accomplished with the aid of a control current of exhaust gas tapped off from the exhaust line and conducted back upstream to the junction of the main channel and the bypass channel. The force of this control current deviates the exhaust gases from their normal path and causes them to flow into the bypass channel.
