Abstract (en)
[origin: EP0457287A2] The device, which serves both to control harmful emissions and to lower the noise levels of exhaust gases from internal combustion engines and burners in general, comprises a duct (3) created between the coils (4, 4') of a spiral element and open at either one or both ends; the element is fashioned in a material of low thermal conductivity, and the coiled surfaces exposed to the exhaust gases can be coated with catalytic materials capable of speeding up the reduction or oxidation of pollutants. <IMAGE>
