Abstract

The invention concerns a reactor for afterburning of unburned constituents in the exhaust of an internal combustion engine, consisting of a jacketed heat-insulated reactor chamber into which at least one inlet pipe passing through the jacket and communicating with an outlet passage of the engine opens tangentially, being traversed by exhaust gases mixed with secondary air, and having an outlet pipe for escape of exhaust gases from the reactor chamber. The reactor chamber in cylindrical in shape and the inlet pipe opens into the reactor chamber tangentially and the outlet pipe is passed out of the reactor chamber tangentially from the inlet pipe in the direction offset of flow.
