3308473 - 1080D crankcase vapour/gas recirculation system (Automatic transmission)
The oil vapour emissions are controlled
by a separator (1) which collects the vapours released from the
crankcase using the pipe (2).The difference in temperature between the
separator and the oil vapours causes partial condensation (*).The condensed vapours are sent, via a pipe,
to the crankcase.The uncondensed vapours are sent, through
a pipe (4), to the turbocharger air inlet hose.
