  • Internal combustion engine with afterburning and catalytic reaction in a supercharger turbine casing
    Patent number: 4122673
    Abstract: To remove pollutants in the exhaust gases from a liquid fuel driven engine, a turbosupercharger, including a turbine and a compressor, is combined with the engine to provide both afterburning and catalytic oxidation. The exhaust gases are accumulated to provide combustion in advance of the turbine. Further, air is branched off from the compressor and mixed with the gases flowing through the turbine to afford combustion of the gases after they pass through the turbine. Catalytically active surfaces are located within the turbine for the reduction of nitric oxides.
