Description And Operations: Overview

WARNING: This page is about a different car, the 2018 Land Rover Range Rover, 2017 Land Rover Range Rover, and 2016 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.

Depending on the market, the TDV6 3.0L diesel engine is available in two variants. The single turbocharger variant uses a single Variable Geometry Turbine (VGT) type turbocharger, the twin turbocharger variant uses two turbochargers. The twin turbocharger variant comprises a VGT type turbocharger (primary turbocharger), and a fixed vane type (secondary turbocharger) turbocharger.

On the twin turbocharger variant, both turbochargers are used in a parallel sequential turbocharging system, which enables the engine to achieve quick throttle response at low engine speeds and efficient use of exhaust gas energy at high engine speeds. The primary turbocharger operates through the entire engine speed range, but is at its most efficient, at engine speeds of up to 2800 RPM it is running in a mono turbocharger mode. At engine speeds above 2800 RPM under load, the secondary turbocharger comes into operation, with both of the turbochargers running in a parallel bi-turbocharger mode.

The twin turbocharger system comprises the two turbochargers, the turbine intake shut-off valve solenoid, and the charge air intake valve, which incorporates the charge air recirculation solenoid and the charge air shut-off valve. The operation of the system is controlled by the Engine Control Module (ECM).

The turbochargers and the charge air intake valve are interconnected by the charge air ducts of the intake air distribution and filtering system.
