Exhaust gas recirculation system in a supercharged engine, the engine (E) comprising a predetermined number of cylinders, an intake manifold (4) and a pair of exhaust manifolds (5, 5'), distinct and separate from each other, each one of them being connected to half of the cylinders of the engine (E) and a twin-scroll (10, 11) turbine (6), wherein the first scroll (10) has an inlet connected to the first exhaust manifold (5) and the second scroll (11) has an inlet connected to the second exhaust manifold (5'). The first (5) of the exhaust manifolds being connected to the intake manifold (4) to realize the exhaust gas recirculation (EGR). Both scrolls have a variable geometry and can be regulated in a reciprocally independent way. |
