Κατσε γιατι μπερδευτηκα! Εγω ρωταγα για τη λιπανση του V10 των Μ5, Μ6, οχι για τον straight 6 των Μ3 Ε46. Γι αυτο και γραφω οτι ειμαι εκτος θεματος. Αν συγκεντρωθει πληροφορια για λιπανση γι αυτα τα 'ειδικα' μοτερ καλο θα ταν να ανοιξει ξεχωριστο θεμα για να μη μπερδευομαστε στα θεματα που αφορουν μονο Μ3 Ε46.
Καθε τεχνικη πληροφορηση παντως ανεξαρτητα αμαξιου ή μοτερ ειναι ευπροσδεκτη και αρκετα ενδιαφερουσα.

Όπως λέει και το press release της BMW για το Μ3:

Consistent and reliable oil supply with longitudinal and lateral acceleration
up to 1.4 g ensured by two oil pumps and wet sump oil lubrication
optimised for supreme dynamic behaviour.

Reliable oil supply even under extremely dynamic conditions.
The high standard of driving dynamics offered by the BMW M3 obviously
calls for a sophisticated supply of oil to and within the engine. Indeed,
the engine oil supply is conceived for longitudinal and lateral acceleration of
up to 1.4 g – far more than the forces acting on a passenger’s body when
taking off and landing in a jet aircraft.
The eight-cylinder is reliably supplied with lubricant in all driving situations by
two volume flow-controlled pendulum shift cell pumps consistently providing
exactly the right amount of oil required by the engine. This is ensured by a
change in eccentricity (off-centre arrangement) of the inner rotor in the pump
versus the pump housing as a function of oil pressure in the main oil duct.
In consideration of the physical forces and loads encountered in an extremely
dynamic driving situation, it is conceivable that when the driver applies the
brakes particularly hard, for example, the supply of oil to the oil sump serving
as an interim storage reservoir would not be sufficient, particularly as the
oil sump is positioned behind the front axle subframe for reasons of space.
So if the worst came to the worst, lubrication would be interrupted completely.
This is however prevented by the concept of “optimum-dynamic wet sump
lubrication”, a system with two oil sumps: a small oil sump in front of the front
axle subframe and a large oil sump behind the first one. A separate
recirculation pump draws oil from the small oil sump at the front under all
conditions and feeds the oil to the larger sump at the rear. The larger
sump, in turn, is carefully sealed off in order to avoid any splash losses and
the formation of foam.
The new eight-cylinder power unit from BMW M also comes with electronic oil
level control determining the level of oil by means of a sensor fitted in the oil
sump. The data thus measured is transmitted by a serial databus to the engine
management evaluating this data by means of various algorithms. The value
thus obtained, corrected by the car’s lateral and longitudinal acceleration,
is then presented to the driver in the instrument cluster.

Επίσης:

Consistent and reliable oil supply even under extremely dynamic
driving conditions.


Two volume-flow controlled pendulum slide cell pumps supply the eightcylinder
efficiently with lubricant, consistently delivering exactly the right
amount for the engine. Wet sump lubrication optimised for engine dynamics,
in turn, ensures appropriate lubrication also in extreme braking manoeuvres.
The entire system features two oil sumps – a small one in front of the front
axle subframe and a larger sump further back. A separate reflow pump, in turn,
extracts oil from the front oil sump and pumps it to the sump at the rear.

Kαι ο S54 έχει εφεδρική αντλία λαδιού, η οποία τραβάει λάδι από τις άκρες της ελαιολεκάνης όταν ο αισθητήρας επιτάχυνσης του ABS/DSC κλπ δει πάνω από 1g, αυτό το θυμάμαι από την παρουσίαση της Μ3 το 2001 στα τεχνικά χαρακτηριστικά.
