Device for operating six cylinder V-type internal combustion engine of motor car, has air circulation device connected to portions of pressure lines and fixed with compressors with suction line dependent on modes of engine

摘要

The device has parallely-connected exhaust gas superchargers (14, 16) with exhaust gas turbines (14a, 16a) connected to exhaust gas flows of a sequential charger-integrated internal combustion engine i.e. six cylinder V-type internal combustion engine, and compressors (14b, 16b) conveying combustion air over loading pressure lines (42, 44) to the engine. The lines are separately guided to combustion chambers. An air circulation device (68) is connected to separate portions of the lines and fixed with the compressors with a suction line (40) dependent on operating modes of the engine.
