OIL PUMP

1. Pressure regulator valve

2. Stator

3. Rotor

The oil pump is built into the timing chain casing.

It is operated by the crankshaft via a torsional vibration damper. The pressure regulator valve is accessible from outside and opens throughout a pressure range from 4 to 6 bars.

The two main lubrication channels are fied via channels cast into the cylinder block. These main channels feed the entire engine lubrication system, bearings, cylinder head, chain and balancing shafts.

OIL FILTER

1. Oil filter housing

2. Oil filter cover

3. Filter cartridge

The oil filter cartridge seat is cast into the engine block.

The oil filter consists of a paper cartridge. The filter cover, which also contains the bypass valve, is screw-in.

ENGINE OIL PUMP

The oil pump module is incorporated in the engine block front cover and is operated directly by the crankshaft. The oil supply is regulated by a pressure relief valve.

The two main lubrication ducts are supplied by means of channels produced through fusion behind the engine block. These main ducts supply the entire engine lubrication system, bearings, cylinder head and camshaft timing variation system.

1. Oil pump - crankcase front cover integrated module

2. Relief valve

3. Oil pump rotors

4. Oil pump rear cover

OIL FILTER

The oil filter cartridge housing is part of a compact, aluminium alloy module which includes a water-oil heat exchanger.

Fitting the module on the left side of the engine block allows a direct connection with the water circuit assisting the rapid heating of the oil whilst the engine is warming up and a reduced oil pressure loss.
