Abstract
La présente invention concerne un dispositif d’injection d’air secondaire pour moteur à combustion interne équipé d’une ligne d’admission (1) d’air et une ligne d’échappement (2) des gaz brûlés, ce dispositif comprenant une conduite (3) d’air secondaire destinée à s’étendre entre la ligne d’admission (1) et la ligne d’échappement (2), une pompe à air (4) disposée dans la conduite (3) d’air secondaire, une vanne (5) de contrôle du passage d’air disposée dans la conduite (3) d’air secondaire, en aval de la pompe à air (4), caractérisé en ce qu’il comprend un tube (7) d’évacuation des condensats relié à la conduite (3) d’air, entre la pompe à air (4) et la vanne (5), le tube (7) d’évacuation étant équipé d’un clapet anti-retour (8) taré pour s’ouvrir et permettre l’évacuation des condensats quand la pression d’air dans conduite (3) d’air secondaire dépasse un seuil de pression prédéterminé.
