摘要： An exhaust chamber for internal combustion engines of motor vehicles, in which the exhaust gases, before being discharged to the atmosphere, are passed through one of two coaxial chambers, with the inner chamber being filled with a suitable catalyst for the combustion of unburnt substances, depending on the load condition of the engine, so that the catalyst is contacted by these exhaust gases only at low working power.
