%X Cet article passe en revue les diff¨¦rents syst¨¨mes catalytiques de post-traitement utilis¨¦s actuellement sur la plupart des automobiles pour limiter leurs rejets de polluants. Les syst¨¨mes sont diff¨¦renci¨¦s par leur mode de fonctionnement, le type de moteur ¨¤ d¨¦polluer (deux-temps, quatre-temps, diesel ou essence) ou par leur mode de r¨¦alisation. Les nouvelles orientations, pr¨¦vues pour respecter les futures r¨¦glementations antipollution, sont ¨¦galement d¨¦crites. On montre que certains v¨¦hicules prototypes, ¨¦quip¨¦s de moteurs ¨¤ combustion interne, sont capables d'avoir des ¨¦missions tr¨¨s proches de z¨¦ro tout comme les v¨¦hicules ¨¦lectriques. A review is made of the various types of exhaust gas aftertreatment systems presently used on most vehicles to reduce pollutant emissions. The systems are differentiated by their mode of action, according to the engine type to be depolluted (two-stroke, four-stroke, diesel or spark-ignition), and by their type of make-up. The major developments foreseen in the future, in view of compliance with the new legislations, are described. It is shown that some prototype vehicles with internal combustion engines are able to emit pollutant quantities really close to zero, such as electric cars.
