Abstract

La présente invention concerne une installation de moteur à combustion interne à hydrogène. L’installation (1) comprend une ligne d’échappement (4) avec un moyen de catalyse à réduction sélective des NOx sensible à l’hydrogène (10). De plus, l’installation comprend une ligne de captage de l’hydrogène (5) présent au sein d’un carter (20) du moteur à combustion interne (2), cette ligne de captage de l’hydrogène (5) injectant au moins une partie de l’hydrogène dans la ligne d’échappement (4) en amont du moyen de catalyse à réduction sélective des NOx sensible à l’hydrogène (10).
