Abstract

Les gaz d'échappement circulent à l'intérieur d'un faisceau (2) refroidi par un liquide réfrigérant. La longueur efficace EF du faisceau (2) est déterminée en fonction de la section efficace S de passage des gaz dans le faisceau (2) de façon telle que le rapport EF/S entre la longueur efficace EF du faisceau (2) et la section efficace S de passage des gaz dans le faisceau (2) soit compris entre une valeur maximale EF/S max et une valeur minimale EF/S min pour lesquelles l'encrassement du faisceau est minimal. Application aux moteurs à combustion interne, en particulier de véhicules automobiles.
