Abstract

L’invention concerne un moteur à combustion interne (1) comprenant : - une chambre de combustion, - une ligne d’admission (20) d’air frais, - une ligne d’échappement (80) de gaz brûlés qui comprend au moins un catalyseur (83), - un turbocompresseur (30) qui comporte une turbine (82) et un compresseur (22), - un circuit d’injection (60) de carburant qui comprend un réservoir de carburant (61), et - une ligne d’évacuation (50) de vapeurs de carburant, qui prend naissance dans le réservoir de carburant, qui débouche dans la ligne d’échappement en amont du catalyseur, et qui comprend un réservoir de stockage des vapeurs de carburant (51) et une vanne de régulation (52) du débit de vapeurs de carburant. Selon l’invention, la turbine est située en aval du catalyseur, et la ligne d’évacuation comporte une pompe (53) adaptée à faire circuler les vapeurs de carburant. Figure pour l’abrégé : Fig. 1
