An assembly can include a turbine housing that includes a bore, a wastegate seat, wastegate passages that extend to the wastegate seat and a divider wall disposed between the wastegate passages where the divider wall includes a divider wall surface; a rotatable wastegate shaft configured for receipt by the bore; a wastegate arm extending from the wastegate shaft; and a wastegate plug extending from the wastegate arm where the wastegate plug includes a contact portion that contacts the wastegate seat to cover the wastegate passages in a closed state and a mesh that contacts the divider wall surface in the closed state.

Turbine wastegate

A turbocharger turbine wastegate assembly includes a turbine housing that includes a wastegate seat and a bore; a bushing with a stepped bore that includes an axial face; a wastegate that includes a shaft, a plug and an arm, where the shaft includes an end portion, a first axial face, a journal portion, a second axial face and a shoulder portion, where the first axial face is defined at least in part by an end portion diameter and a journal portion diameter, and where the second axial face is defined at least in part by the journal portion diameter and a shoulder portion diameter; a mesh spacer disposed radially about an axial length of the end portion of the shaft between the axial face of the stepped bore of the bushing and the first axial face of the shaft; and a control arm connected to the end portion of the shaft where an axial length of the bushing is disposed between the mesh spacer and the control arm.
