Porsche Cayenne Diesel - Variable Turbine Geometry (VTG)

Variable Turbine Geometry (VTG)

The turbocharger in the Cayenne Diesel features Variable Turbine Geometry (VTG). The gasoline-flow from the engine is channelled onto the turbines via electronically adjustable guide vanes. By changing the vane angle, the system can replicate the geometry in all types of turbo, large or small, and thus achieve the optimum gasoline-flow characteristics. As a result, even at low engine rpms, the turbine speed is maximized. For a significant increase in boost pressure, excellent cylinder charging plus greater power and torque.
