Abstract
A turbocharger includes: an inflow passage to guide a fluid to a housing space for a turbine wheel; an exhaust passage to discharge the fluid having rotated the turbine wheel from a turbocharger body; a bypass passage connecting the inflow passage and the exhaust passage; a valve unit having one valve for a communicating portion between the exhaust passage and the housing space, and another valve for the bypass passage; an actuator to turn the valve unit and a stem connected to the valve unit about an axis of the stem; and a controller to operate the actuator. The controller adjusts the opening of the bypass passage by turning the valve unit within a specific range about the axis of the stem when a specific condition is met, and closes the exhaust passage by turning the valve unit beyond the specific range when the specific condition is not met.
