THE MATERIALS RELEASED BY THE INTERNAL COMBUSTION OF ENGINE ARE UNBURNED HYDROCARBONS, CARBON MONOXIDE, CARBON DIOXIDE, OXIDES OF NITROGEN, OXIDES OF SULPHUR, CARCINOGEN, PARTICULATES (SMOKE), LEAD COMPOUND, WATER VAPOUR AND ODOUR. CONVENTIONAL TRAPPING SYSTEM OF EXHAUST PIPE ARE UNABLE TO TRAP THE POLLUTANTS EFFECTIVELY. SELECTIVE SYSTEM OF TRAPPING HAS BEEN DEVELOPED BASED ON VORTEX (SPIRAL) FLOW OF GASES FROM ENGINES. THE SYSTEM INSTALLED AT THE END OF EXHAUST PIPE AND IT WILL TRAP TOXIC GASES AND OTHERS MATERIALS. THE SYSTEM CAN BE MAINTAINED EASILY BY REPLACING ADSORBERS INSIDE THE TRAPPING CHAMBER WHEN THE TRAPPING PROCESS IS REDUCED. CATALYTIC CONVERTER ALSO CAN BE USED IN THE SYSTEM INSTEAD OF ADSORBER.
