Abstract:
PURPOSE:To permit the supercharge operation having high efficiency by forming a partitioning wall on the downstream side of a communication pipe for the first exhaust passage connected with a twin scroll turbine. CONSTITUTION:A plurality of cylinders are divided into two groups, and turbosuperchargers 15 and 17 are installed into each cylinder group. The first and second exhaust passages 13 and 14 connected with the turbosuperchargers 15 and 17 are allowed to communicate through a communication pipe 30. A partitioning wall 34 is formed on the downstream side from the communication pipe 30 in the first exhaust passage 13. The interference of exhaust is prevented by the partitioning wall 34 when the selector valves 31 and 32 are opened. Therefore, the supercharge having high efficiency is permitted.
