The invention relates to a device and a process for lowering the noxious substances content, particularly of CO and CO2, in the exhaust gases discharged into the atmosphere as a consequence of the operation of a heat engine equipping the land, sea and aerial motor vehicle, with a view of reducing the greenhouse effect generated thereby, as well as to an exhaust pipe equipped with such devices. According to the invention, the device consists of two semicasings (1 and 2) wherebetween there are located some pairs (A) of ring-shaped elements (3 and 4) made of copper and of lead, respectively, provided with some transverse cuts (e and T), and in each element (3) there are drilled some through holes (i) whose centres describe longitudinal lines parallel between them and transverse lines parallel between them as well as some secondary through holes Q) whose holes describe an evolute (k) of a logarithmic shape. |
