MOTEUR A COMBUSTION INTERNE COMPRENANT DES CONDUITS D'ADMISSION USINES EN CHANFREIN

摘要

The engine (2) has a head (4) including gas inlet ducts that are opened on an outlet face of the head and equipped with a movable closing valve. The ducts have a valve seat to receive valves and throats. Geometries of the throats are adopted to generate a tourbillon level in cylinders (6). The geometries of the throats are different from each other, and the geometries are adopted so that the level in one of the cylinder is equal to the level in the other cylinder. One of the throats has a revolution geometry around an axis of the valve seat.
