Air intake device for cylinder of combustion engine i.e. direct injection diesel engine, of motor vehicle, has filling part having circular shaped section to minimize leakage at level of obturation unit when obturation unit is closed

Air intake device for cylinder of combustion engine i.e. direct injection diesel engine, of motor vehicle, has filling part having circular shaped section to minimize leakage at level of obturation unit when obturation unit is closed

The device has an air intake conduit divided into two parts having a filling part (12b) obturated by an obturation unit (16) i.e. flap. The filling part has a circular/ellipsoidal shaped section to minimize leakage at a level of the obturation unit when the obturation unit is closed. A swirl part (1...

description The device has an air intake conduit divided into two parts having a filling part (12b) obturated by an obturation unit (16) i.e. flap. The filling part has a circular/ellipsoidal shaped section to minimize leakage at a level of the obturation unit when the obturation unit is closed. A swirl part (12a) of the intake conduit has a rectangular section. An internal separation wall (15) extends over entire length of the intake conduit. An independent claim is also included for an air intake method for a cylinder of a combustion engine. Dispositif d'admission d'air dans un cylindre (1) de moteur à combustion, comprenant au moins un conduit d'admission d'air (12) divisé en deux parties (12a ; 12b) dont une partie de remplissage (12b) est obturable par un moyen d'obturation (16), caractérisé en ce que la partie de remplissage (12b) comprend une section adaptée à la minimisation des fuites au niveau du moyen d'obturation (16) lorsque ce dernier est fermé pour limiter la baisse de perméabilité du conduit d'admission (12).
