Turbocharger - Overview (G1551096): Overview

Air charging of the GTDi 2.0L PETROL engine is provided by a fixed nozzle Borg Warner K03 turbocharger.

The turbocharger consists of two turbo elements; a turbine and a compressor. These elements are enclosed separately in cast housings and mounted on a common shaft, which rotates in a single semi-floating bearing.

The turbocharger receives water and oil cooling to allow it to maintain the optimum operating temperature and protect the bearings from overheating.

The turbocharger has a pressure operated turbine intake shut-off valve which is controlled by the ECM (engine control module).
