COMBUSTION GAS RECIRCULATION DEVICE FOR TURBOCHARGED ENGINES, ENGINE COMPRISING SAID DEVICE, AND MOTOR VEHICLE COMPRISING SAID ENGINE

摘要

The invention relates to a combustion gas recirculation device for turbocharged engines, to an engine comprising said device, and to a motor vehicle comprising said engine. Said device enables a pressure drop to be avoided in the intake manifold when the mean pressure in the intake manifold exceeds the mean pressure in the exhaust manifold, and comprises a casing (3) arranged between the exhaust manifolds (5) and the intake manifolds (6) and containing a disk (1) embodied in such a way that it rotates with the engine in a synchronised manner and opens and/or closes a conduit (9) connecting the inside of the casing (3) to each exhaust manifold, by means of the arrangement of a plurality of radial openings (8) in the disk (1), enabling the combustion gas to be recirculated from the exhaust manifolds (5) when the maximum instantaneous pressure is reached in same.
