Abstract

Système de moteur à cycle fermé comprenant une unité de moteur qui fonctionne par combustion de carburant à l'aide d'un gaz de combustion, et un circuit de gaz assurant une communication fluidique entre l'admission et l'échappement de l'unité de moteur. En fonctionnement, l'unité de moteur produit des gaz d'échappement. Le circuit de gaz comporte un absorbeur, pour absorber au moins partiellement les gaz d'échappement, et un dispositif de résistance à l'écoulement. Le dispositif de résistance à l'écoulement est situé entre l'absorbeur et l'admission, et est disposé de telle sorte que la pression au niveau de l'admission est inférieure à la pression au niveau de l'échappement. Cette disposition améliore le rendement de l'absorbeur, et donc le rendement total du moteur. Un procédé d'actionnement de ce système de moteur, et des véhicules comprenant ce système de moteur, sont également décrits.
