Positive Crankcase Ventilation: Description and Operation



Positive Crankcase Ventilation







The hose routing for the crankcase ventilation system has been altered. Downstream of the oil separator, the crankcase ventilation system is routed to either side of the double low distribution pipe, so as to attain identical mixture formation for bank 1 and bank 2 when the distribution pipe flap is closed.

The ventilation hose of the tank vent valve leads directly behind the electronic throttle into the distribution pipe from below.
