ーボチヤージヤの排気バイパス装置。 In a turbocharger in which two scroll passages that open to a common turbine wheel in a turbine housing are arranged side by side in the direction of the turbine rotational center axis, one scroll passage extends in the turbine housing in the turbine axis direction from the middle of each scroll passage and is parallel to the turbine rotational center axis. Two independent bypass passages of different lengths are formed at orthogonal end faces that open into the exhaust passage downstream of the turbine, and a bypass control valve for controlling opening and closing of the bypass passage is provided on the end face, and the bypass passage and each scroll are provided with a bypass control valve for controlling opening and closing of the bypass passage. An exhaust bypass device for a turbocharger, characterized in that a connecting portion of a longer bypass passage is located on the outer peripheral side from a turbine rotation center axis than a connecting portion of a shorter bypass passage.
