  • Exhaust manifold for an internal combustion engine
    Patent number: 3935705
    Abstract: A manifold for an internal combustion engine to serve also as an exhaust gas depollution reactor. An ante-chamber into which the gas initially flows, can be made to operate as a post-combustion chamber by introduction of excess combustion air while the engine is operating under the usual richer fuel/air mixture on start-up. The catalytic reaction components are located in a downstream main chamber with which the ante-chamber shares a common partition wall for heat transfer purposes.
