Diverter Control

Diverter Control







When the throttle is closed quickly (deceleration), the boost pressure increases in the pressure system in front of the throttle because the compressor of the turbocharger continues running. The new 911 Turbo (997) is also equipped with a diverter valve for each cylinder bank to blow off the excess boost pressure. In contrast to the 911 Turbo (996), however, this is not accommodated separately, but is integrated in a space-saving and compact manner in the compressor housing of the turbocharger. The Motronic control unit activates the electro-pneumatic switching valve, which then opens the diverter valve by means of a vacuum.
