Disclosed are an apparatus, system and method for purifying exhaust gases from internal combustion engines which enable to remove PM and various noxious chemicals such as NOx, SOx, HC, CO and CO2 from the exhaust gases at the same time. An apparatus (6a) for purifying exhaust gases from internal combustion engines comprises a filter main body (90). The filter main body (90) comprises a first port (74) for introducing an exhaust gas, a second port (84) for discharging the exhaust gas, a first filter (92) which is arranged closer to the first port (74) than to the second port (84), a second filter (94) which is arranged closer to the second port (84) than to the first port (74), and a space (96) arranged between the first filter (92) and the second filter (94). La présente invention concerne un appareil, un système et un procédé servant à purifier les gaz d'échappement de moteurs à combustion interne et permettant d'éliminer simultanément les matières particulaires (PM) et divers produits chimiques toxiques tels que NOx, SOx, HC, CO et CO2 des gaz d'échappement. L'appareil (6a) permettant de purifier les gaz d'échappement de moteurs à combustion interne comprend un corps principal de filtre (90). Le corps principal de filtre (90) comprend un premier orifice (74) permettant d'introduire le gaz d'échappement, un second orifice (84) servant à décharger le gaz d'échappement, un premier filtre (92) disposé de façon qu'il soit plus proche du premier orifice (74) que du second orifice (84), un second filtre (94) disposé de façon qu'il soit plus proche du second orifice (84) que du premier orifice (84) et un espace (96) situé entre le premier filtre (92) et le second filtre (94).
