PURPOSE:To moderate air fuel ratio by providing variable blades at the inlet of an compressor so as to adjust opening degree thereof in accordance with load. CONSTITUTION:Variable blades 23 are arranged in parallel inside an inlet duct 18 which is disposed at the inlet of a compressor. A shaft which extends from the upper point and the lower point of each of the variable blades 23 is prolonged to the outside of the duct 18. A pinion 22 provided at one end of each of the shafts is engaged with a rack 21 which is reciprocated by an actuator 19. The variable blades 23 can be adjusted as that the blades are opened at small degree at the low load time and opened at wide degree at the high load time, thereby moderating air fuel ratio. |
