Twin scroll turbine housing

Abstract

A turbine housing can include a first scroll having a first scroll inlet; a second scroll having a second scroll inlet; a divider wall disposed between the first scroll and the second scroll, where the divider wall includes a machined divider wall tip at an inner perimeter that defines a first outlet throat of the first scroll and a second outlet throat of the second scroll, where the divider wall includes a first planar annular machined surface that defines a portion of the first scroll and that transitions to the machined divider wall tip at a first angle and a second planar annular machined surface that defines a portion of the second scroll and that transitions to the machined divider wall tip at a second angle, where the first angle and the second angle define a cross angle, and where the cross angle is greater than 25 degrees and less than 65 degrees.
