Method and device for recycling a combustion engine burnt gases

摘要

The invention concerns a method for managing the recycling of a combustion engine (12) burnt gases comprising an intake manifold (16) and an exhaust manifold (18) of burnt gases connected to the intake manifold (16) by a recycling conduit (22) wherein is interposed a mobile valve (10) controlled so as to allow, or respectively prevent, the gas flow between the exhaust manifold (18) and the combustion chamber (14). The invention is characterised in that the valve (40) is in closed position when the pressure of the burnt gases in the exhaust manifold (18) is lower than the pressure in the intake manifold (16) and that the opening followed by the closing of the valve (40) is controlled when the pressure of burnt gases in the exhaust manifold (18) is not lower than the pressure in the intake manifold (16).
