- the exhaust gas e exhausted from an engine flows into the turbine rotor blade 116 through both scroll passages 106 and 108, and rotates the turbine wheel 110.

Therefore, a space for mounting the coupling is required, and therefore the front partition wall 128 of the turbine housing 102 has a shape inclined to the front side (exhaust gas outlet side).
- the dimension of a radial direction must be enlarged, but there exists a restriction
- the turbine housing 102 forming the scroll flow path is entirely inclined toward the front side, so that the front side scroll flow path 108 must be inclined toward the front side. Therefore, as indicated by the arrows in FIG. 3, the flow field of the exhaust gas e is not symmetric between the front side and the rear side with respect to a line orthogonal to the front edge 114a of the turbine rotor blade 114. As a result, a flow rate difference occurs between the front side flow path and the rear side flow path. This flow rate difference causes a difference in operating conditions on the engine side on the upstream side of the exhaust gas, leading to a decrease in engine performance.
- the turbine housing that forms the scroll passage must be enlarged in the radial direction in order to secure the cross-sectional area of the scroll passage, and the narrow layout cannot be accommodated. There is.

It is preferable that the entire area can be diffused.

Therefore, although the timing of the exhaust gas flowing into the turbine rotor blades from both scroll flow paths is different, an equal flow field can always be formed by allowing the exhaust gas to diffuse throughout the outlet openings of both scroll flow paths. Therefore, drift and the like can be suppressed, and a decrease in turbocharger performance can be prevented more effectively.
