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.
