3232854 - 1080D crankcase vapour/gas recirculation system

The oil vapour emissions are controlled by a separator (1) which collects the vapours released in the cylinder heads using a pipe (2).The difference in temperature between the separator and the oil vapours causes partial condensation.The condensed vapours are sent to the cylinder head through the pipe (3).The uncondensed vapours are directed, through pipe (4), to the intake housing.
