Closed crankcase ventilation
P0006038
The main component in the new closed crankcase
ventilation comprises a separator (
A
) directly
attached to the engine block left side. The separator
is driven by a turbine(
3
), which is in turn driven by oil
from the engine lubrication system via a channel. The
turbine is connected to a drive shaft (
4
) with a number
of discs (
5
) rotating at approximately 8,000 rpm when
the engine is running normally. There is a pressure
regulator (
6
) and membrane (
7
) on the side of the
separator that shuts off the flow to the separator if too
great a pressure drop occurs.
After having passed the oil traps in the upper timing
gear cover and valve cover (refer to Open crankcase
ventilation), the crankcase gasses are led to the inlet
in the top of the separator via a hose connection (
1
)
and enter the separator from above directly over the
center of the rotating discs. The oil and heavier parti-
cles are thrown out to the periphery by centrifugal
force and can be led back to the oil sump together with
the oil driving the turbine.
The cleaned gases are led to the turbocharger inlet
side via a connection (
2
).
