Flexible porous non-pollutive tube

ANTI-POLLUTANT FLEXIBLE POROUS TUBE, which integrates the intake system of combustion engines, comprising dirty air inlet nozzle (7-A) with a normally circular opening (7-A1) of the upper compartment (7) of the air filter, which has the filter element (9) and its internal brackets (10) placed in the upper (7) and bottom (8) compartments of the air filter, with the bottom compartment (8) featuring a clean air outlet nozzle, (8-A) normally circular opening (8-A1), with a conventional seal tube (11) that is coupled around the clean air outlet nozzle (8-A) and the injection chamber (12) installed over the combustion chamber (13), which has coupled onto it the exhaust tube (13), while the flexible tube is comprised of a variable width tape made of non-porous material (2), namely aluminum, PVC, thermoplastic or other material in a helical, interleaved and discontinued arrangement on the tube, with an external wall or cover (1) and internal wall or coating with a smaller diameter (3) that allows the control of porous bands (5) on the tube structure, determining the variable width tape of non-porous material (2) by its width or arrangement on a porous band (4), on the tube structure, with the external walls or covers (1) or internal walls with a smaller diameter (3) of the tube being comprised of tapes formed by interleaved textile tapes, made of a porous material, with a variable width, coiled and glued, characterized due to being arranged in a helical, interleaved and discontinued manner on the tube walls, with the porous material textile tapes containing activated carbon (6) in a agglomerated, powder or granulate form.
