PROBLEM TO BE SOLVED: To improve the low-speed torque and acceleration response and also improve the engine ratio output by using the same impeller as the impeller used for a vortex blower in a turbine and a blower to constitute a different supercharger, and using this as the auxiliary supercharger for a turbo charger that is a main supercharger. SOLUTION: The exhaust gas of an engine 1 is guided from an exhaust manifold 2 to the turbine 5b of a turbo charger 5 through an exhaust pipe 12 to rotate a radial blade compressor 5a through a shaft 5c. The exhaust gas discharged from the turbine 5b is guided to the inlet 7i of a vortex charger 7 through a piping 16. An exhaust passage is formed on the circumferential part of a vortex turbine impeller 7b, and the turning flow of exhaust gas is carried thereto to rotate the vortex turbine impeller 7b. A valve 10 arranged in a piping 14 is closed, and the intake air is guided to the blower inlet 7g of the vortex charger 7 through a bypass piping 15 arranged on the upper stream thereof to further raise the pressure by a vortex blower impeller. |
