Description And Operation: Turbocharger: Overview
WARNING: This page is about a different car, the 2018 Land Rover Discovery and 2017 Land Rover Discovery. However, it is still accessible from the selected car via links, so may be relevant.
The TDV6 3.0L Diesel engine is equipped with a Variable Geometry Turbocharger (VGT). The VGT makes it possible to vary the exhaust gas flow of the turbine, dependent on engine operation. This improves the power transfer to the turbine wheel and compressor, particularly at low engine speeds, thus increasing the boost pressure. The VGT operates through the entire engine speed range, but is at its most efficient, at engine speeds of up to 2800 RPM.
The VGT is interconnected by the charge air ducts of the intake air distribution and filtering system. For additional information, refer to: INTAKE AIR DISTRIBUTION AND FILTERING .
The operation of the system is controlled by the Powertrain Control Module (PCM).
