ャージャ。A turbine housing in which an exhaust passage is divided into multiple parts by a partition wall, a controller to which detection signals from an engine speed sensor, an engine load sensor, and an exhaust brake sensor are input, and a fluid supply passage to an actuator based on the output signals of the controller. An on-off valve means for opening and closing, an actuator cylinder operated by the fluid pressure in response to the opening and closing operation of the on-off valve means, and a divided passage connected to the actuator cylinder and provided between the inlet of the turbine housing and the exhaust manifold. It has a partition plate that sequentially closes the divided passages except for the last passage, and is also combined with an exhaust brake configured such that the partition plate further narrows the divided passages only when an exhaust brake signal is issued by turning on the clutch and turning off the accelerator pedal. variable capacity turbocharger.
