B. Blow By System

Blow By Circuit Schematics Layout :

In order to reduce the blow by gas emission, the

blow by gas is directed to the intake manifold

through the oil mist separator which separates the

oil from the blow by gas and allows the air to pass

to the intake manifold.

Blow by gases are drawn from crankcase and

cylinder head cover.

Components :

a) Oil Mist Separator :

The oil mist separator separates oil from the blow

by of the engine and sends it back to engine oil

sump. The remaining air and other gases are sent

to the inlet manifold.

There is a spring loaded diaphragm valve

provided on the oil separator outlet which

prevents the flow of excessive blow by gasses

from the oil separator to the inlet manifold in case

the air filter is chocked and high suction starts

acting on outlet port of oil separator.

No leakage past diaphragm or top cover of oil

separator is permitted. Replace the assembly if

there is any leakage or found defective.
