RECIRCULATION CIRCUIT FOR VAPOURS
COMING FROM THE CRANKCASE ( B L O W -
BY)
The crankcase emissions are composed of mix­
tures of air/diesel and exhaust gases which es­
cape from the piston rings, in addition to lubri­
cant oil vapours.
They are defined as blow-by or breather gases.
The breather gases coming from both the
crankcase (2) and the cylinder head (5) reach
the separator (1).
In the separator (1) the gases lose some of the
oil dissolved in them which return to the sump
via the pipe (3) in the form of drops.
The remaining gases, on the other hand, are di­
rected, through the pipe (4) to the intake circuit.
