A turbocharger wastegate assembly includes a turbine housing that includes a chamber, a bore, two exhaust passages, a divider wall disposed between the two exhaust passages, and a wastegate seat, where the divider wall includes a divider wall surface; and a wastegate that includes a shaft, an arm and a plug, where the shaft is received by the bore of the turbine housing for rotation about an axis of the shaft to orient the plug in a closed state and to orient the plug in an open state, where, in the closed state, a contact portion of the plug contacts the wastegate seat and a shell portion of the plug defines a clearance with respect to the divider wall surface and extends into the two exhaust passages.

Turbine wastegate

An assembly can include a turbine housing that includes a bore, a wastegate seat and a wastegate passage that extends to the wastegate seat; a bushing configured for receipt by the bore; a rotatable wastegate shaft configured for receipt by the bushing; 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 passage in a closed state and a shell portion that extends into the wastegate passage in the closed state and that defines a clearance with respect to the wastegate seat in an open state. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.
