Crankcase vapour/gas recirculation system

Description 1080D

1.6 16v

During engine operation, the oil vapours and the gases which escape through the piston seals into the crankcase are collected by a special system.

Some of the oil vapours condense and fall back into the crankcase; the remaining vapours are sent to the inlet via the pipes (2) and (5).

At idle speed, the oil vapours flow through pipe (5), and at higher loads through pipe (2). There is a spark out (1) inside the pipe (2) to prevent combustion due to flame returns from the butterfly casing (4).

1.9 JTD 8V

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.

Some of the oil vapours, condensed, drop back into the crankcase; the remaining vapours are sent to the intake through pipes (2) and (5).

At idle speed, the oil vapours flow through the pipe (5); at higher engine loads through the pipe (2). There is a spark out (1) inside the pipe (2) to prevent combustion due to flame returns from the butterfly casing (4).
