Abstract
Dispositif d'injection d'air frais (20) dans un circuit d'échappement d'un moteur thermique à allumage commandé, comprenant : - une culasse (10) dans laquelle sont creusés des conduits d'échappement (11) de gaz brulés dont les ouvertures sont contrôlées par des soupapes d'échappement (12), - un moyen de mesure de température du moteur, - une unité de contrôle (29), caractérisé en que ledit dispositif (20) comprend une rampe d'alimentation (21) d'air frais creusée dans la culasse, agencée à proximité des soupapes d'échappement (12) et connectée aux conduits d'échappement (11) par des passages d'alimentation (24) contrôlés par un système d'ouverture/fermeture (25) mobile entre une position d'ouverture et une position de fermeture des passages d'alimentation (24), lesdits passages d'alimentation sont aptes à être ouverts lors du démarrage du moteur lorsque la température dudit moteur est sous un seuil de température.
