Les normes actuelles d'environnement contraignent les constructeurs automobiles à concevoir de moteurs plus performants et moins polluants. L'un des paramètres entrant en considération pour l'amélioration de la combustion est l'aérodynamique interne propre au conduit d'admission, la chambre de combustion et au piston. Le choix s'est porté sur un moteur diesel à injection directe comportant un conduit d'admission générant à l'origine un important mouvement de rotation de l'air (swirl). Les caractéristiques de l'écoulement ont été modifiées par l'ajout de différents procédés technologiques qui ont permis de mesurer et comparer les degrés de swirl et coefficients de débit de chaque configuration. Les profils des vitesses de ces écoulements ont...
