Welche Motor-Schmierungsart 745i E65 bj 2004?

[BMW_745iL]

Hallo mich würde mal interresieren wie der Motor vom E65 Schmiert sprich welche Schmierungsart er hat??

Würde mich freuen wenn mir da jemand weiter helfen kann!!

Mfg Daniiii 8)

um welchen Motor geht es denn genau? Diesel, Benziner?
Geht es um die Pumpenart?
Oder Trockensumpfschmierung oder aehnliches?

Eigentlich kann man sich ja hier raussuchen mit Eingabe seiner VIN

da sieht man dann was es fuer eine Pumpe ist

Also ich hab den Benziner 745iL!
Und ich mein wie die Kolben schmieren .
Wie ich gehört habe gibt es eine Trockenschmierung und dann wollte ich wissen welche Schmierung ich hab.

Mfg

Objectives of The Module
After Completing this module, you will be able to:
• Describe the two stage oil supply.
• Distinguish the difference between the left and right drive chain tensioning assemblies.
• Explain the Bi-VANOS operation.
• Understand the function of the Variable intake manifold.
• Explain the cooling circuit flow.
• List what chamber A and chamber B is used for in the Bi-VANOS system.
• Identify the Secondary air components.
• Explain how the initial VANOS position is retained when oil pressure is not present.
• List the proper drive belt removal procedure.
• Describe the throttle valve functions.
• Identify the N62B44 designation.


Engine Block
Oil Sump
The oil sump consists of two parts. The upper section of the oil sump is made from cast aluminum and is sealed to the crankcase with a rubber-coated sheet steel gasket. This section of the oil sump has a cross shaped cut out oil filter element recess. The upper section of the oil sump is inter connected to the oil pump and is sealed with a sealing ring. The double panel (noise insulation) lower section of the oil sump is flanged to the upper section of the oil sump.

2. Oil Pump
3. Oil Level / Condition Sensor
4. Lower Section of The Oil Sump
5. Oil Filter Housing
6. Oil Drain Plug

Lubrication System
Crankcase with oil jets

1. Oil Jet for Drive Chain Cylinder Bank 5 - 8
2. Oil Jets for Piston Cooling

The engine oil is supplied by the oil pump to the lubrication points in the engine block and is pumped into the cylinder heads. The following components in the crankcase and cylinder head are supplied with engine oil:

Crankcase

• Crankshaft bearings
• Oil jets for piston cooling
• Oil jet for the drive chain (bank 5 - 8 )
• Tensioning rail for drive chain (bank 1-4)

Cylinder head
• Chain tensioner
• Guide rail on cylinder head
• Hydraulic valve adjustment elements (HVA)
• VANOS supply
• Camshaft bearings
• Overhead oil tubes for the valve gear

Oil Check Valves
Three oil check valves are inserted into each cylinder head from the outside. This prevents the engine oil from draining out of the cylinder head and the VANOS units. The check valves are accessible from the outside, therefore; cylinder head removal is not necessary when changing the check valves.

1. Oil Check Valve for VANOS Intake
2. Oil Check Valve for VANOS Exhaust
3. Oil Check Valve for Cylinder Head Oil Supply

Note: The oil check valves are different in design and should
not be mixed up on installation.

Oil Pressure Switch
The oil pressure switch is located on the side in the bank 1-4 cylinder head.

Oil Pump
The oil pump is mounted at an angle to the crankshaft bearing cap and is driven by the crankshaft using a roller chain. The oil pump is a two-stage gear oil pump with two parallel switched gear clusters.

1. Drive Shaft
2. Mounting Points
3. Oil Filter
4. Pressure Relief Valve (over 15 Bar)
5. Control Valve (Pump Stage/Pressure Control)
6. Oil supply from the oil pump to the engine
7. Oil pressure control tube from the engine to
the control valve.

The two pair of gear clusters are stacked one behind the other and work in two stages. Stage two (both pump supply circuits) is only active in the lower engine speed range up to approx. 2,000 rpm to provide sufficient oil pressure for the VANOS at high oil temperatures. Stage two is deactivated hydraulically at a pressure of 2 bar.

2. Oil Pump Stage 2 6. Oil Pump Housing

Oil pressure control valve in initial position, without pressure.

Stage two = Both pump supply circuits activated with oil pressure less than 2 bar.

Stage two = Oil pressure above 2 bar, pressure control valve
opens channel for stage two to oil sump.

Main pressure control = Oil pressure above 6 bar, pressure control valve opens channel for stage one (slightly) to oil sump relieving excessive pressure.

Oil Filter
The canister type oil filter (3) is located under the engine by the oil sump. The support for the oil filter is integrated in the rear oil pump cover.
The oil filter housing (2 with o-ring) is threaded into the rear of the oil pump cover through an opening in the oil sump. drain plug is integrated in the oil filter housing for draining the filter assembly before the housing
is removed (1 with o-ring).

The filter element support dome contains an over pressure relief valve. If the filter element is blocked, this valve bypasses unfiltered engine oil around the element to the supply lubrication to the engine.

Pressure Control
The oil pressure control valve in the oil pump has two functions:
1. Deactivates stage two oil pump circuit above 2 bar. Stage two is only active in the lower speed range. This is to ensure that there is always sufficient oil pressure for the VANOS units even at high oil temperatures and low speeds. The oil pump power consumption is reduced by deactivating stage two.
2. Monitoring the required oil pressure for the engine. The piston in the control valve is moved by a spring against the engine control pressure which is returning from the engine. This means that precise monitoring of the actual engine oil pressure is possible.
separate pressure relief valve in the oil pump automatically opens at the maximum pressure of approximately 15 bar. This prevents damage in the oil pump especially at low oil temperatures.

Oil Cooling (if equipped)
An oil cooler is used in hot countries. The oil cooler is located in front of the radiator above the A/C condenser. The engine oil flows from the oil pump through a channel in the crankcase to a connection on the generator support. The generator support has an oil thermostat.
A wax element in the oil thermostat continuously opens the inflow to the oil cooler when the oil temperature is between 100 ºC to 130 ºC.
Some of the engine oil always flows past the oil thermostat and through the engine without being cooled, even when the oil thermostat is fully open. This ensures a minimum amount of oil is supplied when the cooler is faulty. A modified generator support, without connections for the oil thermostat, is fitted to vehicles which do not have an oil cooler.
