IMPROVEMENTS IN EXHAUST PIPES OF VEHICLES The improvements presented here apply to the so-called muffler within the exhaust system of vehicles with internal combustion engines . This device (1) includes, according to the improvements, a first part (2) into which the exhaust gases enter, within which are sandwiched parallel decontaminating plates (8). A high percentage of the pollutants will be trapped between them, as a result of the turbulence produced by the funnel (9) through which the gases pass. Decontaminated gases then leave this area (2), and are forced through an entrance (11) provided in an intermediate area ( 3 ) towards further filters (13-13') which complete the decontamination of these polluted gases. This process will be aided by the turbulence created by the air-injection through a channel (14) projected by an electric ventilator (15). As a result the polluted air leaves the exit (6) absolutely clean.
