ABSTRACT:
This device comprises a turbocompressor C whose turbine 7 has a scroll 8a connected to two pipes 5, 6 each connected to the exhaust of a group of cylinders of the engine. The inlet of the scroll is divided by a partition 10 into two conduits 11, 12 which extend the two pipes 5, 6. A regulating flap 15 is provided and constitutes a movable wall of the scroll and includes two extensions 18, 19 which extend on each side of the partition 10 into the conduits 11, 12. This arrangement avoids the phenomenon of a counter-scavenging in the cylinders of the engine and improves the efficiency of the turbine.
