るターボチヤージヤ。 The exhaust gas flow path is branched into two, the scroll portion of the turbine casing is divided into two in the rotational axis direction of the turbine impeller, the exhaust gas flow path is communicated with the two scroll portions, and each of the exhaust gas flow paths is divided into two parts. In a variable displacement turbocharger provided with a control valve for opening and closing at least one of the exhaust gas passages, the flow passage cross-sectional area of the scroll portion communicating with the exhaust gas passage provided with the control valve is set in a straight line from the scroll inlet to the winding end portion. A turbocharger characterized by a larger change.
