Component Description For Oil Separator - Mercedes-Benz OM 471 Introduction Into Service Manual

GF01.20>W>2010H
ENGINES 471.9 in MODEL 963
Location
1 Oil separator
The oil separator (1) is located on the right side of the engine
below the turbocharger.
Task
The engine oil separator (1).contained in the blow>by gas (C) is
separated off with the aid of a centrifuge and passed back into the
oil pan.
Design
1 Oil separator
2 Input fitting (blow>by gas with engine oil)
3 Centrifuge
4 Centrifuge drive wheel
5 Engine oil drain
6 Oil pressure duct
7 Outlet fitting (blow>by gas, cleaned)
8 Pressure control valve
A Separated out engine oil
B Engine oil (to drive the centrifuge)
C Blow>by>gas (with engine oil)
D Blow>by>gas (clean)
Function
The blow>by gas (C) generated by internal leakage at the piston
rings, valve stem seals, turbocharger and compressor passes over
the input fitting (2) into the oil separator (1).
In the oil separator (1) the blow>by gas (C) is led to the centrifuge
(3). The centrifuge (3) is caused to turn driven by the centrifuge
drive wheel (4) which is driven by the engine oil (B) delivered over
the oil pressure duct (6), whereby the rotational speeds can reach
up to 8000 rpm.
The centrifugal force so generated throws the engine oil droplets
contained in the
blow>by gas (C) onto the disc walls where the gather into larger
drops and thrown onto the inner wall of the oil separator (1).

System components
The engine oil (A) separated in this way runs downward along the
inner wall and returns to the oil pan via the engine oil drain (5).
The cleaned blow>by gas (D) is taken out of the oil separator (1)
over the outlet fitting (7) and subsequently over a hose into the
air intake pipe upstream of the turbocharger.
The pressure regulating valve (8) regulates the pressure in the
crankcase.
i The oil separator (1) is maintenance free.
