Title (EN) MULTI-INLET AIR FLOW PASSAGE ARRANGEMENT FOR DIESEL ENGINES
(FR) DISPOSITIF A ADMISSION MULTIPLE POUR L"ADMISSION D"AIR DANS DES MOTEURS DIESEL
Abstract: front page image
(EN)An inlet air passage (14) introduces air into a cylinder bore (12) of a diesel engine (10) in a direction along a flow path substantially tangent to the cylinder bore to provide a swirling of the air within the bore. A second inlet air passage (14) introduces air into the same cylinder bore in a direction along a flow path toward the centerline of the cylinder bore axis which minimizes swirl within the cylinder bore. The non-swirling air flow path is utilized during start up and cold idle and the swirling air flow path is individually used when the engine operates through its intermediate speed range with both air flow paths being simultaneously directed into the cylinder bore during high speed operation of the engine for optimum volumetric efficiency.
(FR)Un passage d"admission d"air (14) introduit de l"air dans l"alesage d"un cylindre (12) d"un moteur diesel (10) suivant une direction d"un passage d"ecoulement substantiellement tangente a l"alesage du cylindre pour produire un tourbillon d"air dans l"alesage. Un second passage d"admission d"air (14) introduit de l"air dans le meme alesage d"un cylindre suivant un passage d"ecoulement se dirigeant vers l"axe median de l"alesage du cylindre, ce qui diminue le tourbillon dans le cylindre. Le passage d"ecoulement d"air non-tourbillonnant est utilise lors du demarrage et pendant le ralenti a froid et le passage d"ecoulement d"air tourbillonnant est utilise individuellement lorsque le moteur fonctionne a des vitesses intermediaires, les deux passages d"ecoulement d"air etant simultanement diriges dans le cylindre lorsque le moteur tourne a haute vitesse, de maniere a obtenir un rendement volumetrique optimum.
