Wastegate

More torque, less consumption means greater reliability

The turbocharger controlled by a wastegate valve limits pressure even at low rpm, optimising torque and fuel consumption. The limitation of pressure is essential for mechanical protection of the engine and the turbo.

The wastegate system permits turbo boost pressure to be kept constant, whilst allowing gradual pressure relief in certain conditions. It is this exhaust gas pressure which, having reached predetermined levels, opens a valve in the exhaust manifold. This permits by-pass of the gases before they impact on the turbo.
