Abstract
A turbine housing for a turbocharger for use in a reciprocating internal combustion engine includes a housing having a housing axis and configured to house a rotatable shaft having a turbine wheel disposed thereon. The housing includes a volute having a volute chamber disposed around the housing axis for receiving the turbine wheel. The volute has a first volute inlet providing a first flow path in fluid communication with the volute chamber and second volute inlet providing a second flow path in fluid communication with the volute chamber. The first volute inlet is circumferentially spaced about the housing axis from the second volute inlet by a phase angle α. The first volute inlet is also radially spaced about the housing axis from the second volute inlet, and may also be axially spaced from the second volute inlet along the housing axis.
