Exhaust gas turbocharger for an internal combustion engine, has a blower and variable turbine geometry with a guide grid and guide vanes of a turbine

摘要

An exhaust gas turbine (3) has a variable turbine geometry (VTG) (8) for variable adjustment in an active turbine inlet cross section towards a turbine wheel. The VTG has a guide grid with adjustable guide vanes (AGV) of a turbine. On its vane's side, an AGV has a separating wall above over a vane's surface to divide a flow area on this vane's side into two separate channels of a guide vane.
