Zusammenfassung:	PURPOSE:To protect accessories of an engine and a cabin of a vehicle against heat, by branching an exhaust passage formed in a bank not having a supercharger into a first passage joining the upstream side of a turbine of a supercharger and a second passage having a waste gate that does not pass the supercharger. CONSTITUTION:Air supercharged by a blower of a supercharger 13 is introduced into a surge tank 7 and then supplied into cylinders 2, 3 formed respectively in two banks 5, 6. Exhaust gas introduced into an exhaust manifold 11 located on the side of a first bank 5 is carried into a turbine housing of the supercharger 13, while exhaust gas introduced into an exhaust manifold 12 located on the side of a second bank 6 is carried into the turbine housing via a first passage 30 since a waste gate 32 is closed at the time of low-load or low-speed operation of an engine. At the time of high-load, high-speed operation of the engine, on the other hand, the waste gate 32 is opened, so that the exhaust gas is carried through a second passage 31.
