The present invention relates to a method of controlling recirculation of part of the exhaust gas of an internal-combustion supercharged engine with a combustion cycle during which at least one cylinder ( 10 ) of the engine is in the intake phase simultaneously with at least one other cylinder ( 14 ) in the exhaust phase, the cylinders comprising at least one intake means ( 18 ) with an intake valve ( 20 ) and at least one exhaust means ( 24 ) with an exhaust valve ( 26 ), said engine further comprising an exhaust manifold ( 32 ) connecting said exhaust means. According to the invention, the method consists, when the engine works with a lean fuel mixture, in controlling opening of the exhaust valve ( 26 ) of cylinder ( 10 ) in the intake phase so as to introduce part of the exhaust gas coming from cylinder ( 14 ) in the exhaust phase and contained in manifold ( 32 ). |
