Brief description of components

  1. Crankcase Made Of Magnesium-Aluminium Composite The crankcase consists of an aluminium-silicon insert, inseparably and seamlessly cast in with a magnesium alloy. For more information, refer to «N52 ENGINE BLOCK - E60, E61, E63, E64, E65, E66, E90, E91»(ref-202154-S10101521332005102600000) .
  2. Innovative Valve Gear Valvetronic The Valvetronic consists of fully variable control of the valve lift combined with the variable camshaft control unit. For more information, refer to «VALVETRONIC - E60, E61, E63, E64, E65, E66, E90, E91»(ref-202154-S22185727372005102600000) .
  3. Volume-Flow-Regulated Oil Pump The new volume-flow-regulated oil pump delivers exactly the oil volume that is actually required. For more information, refer to «N52 ENGINE, OIL PUMP - E60, E61, E63, E64, E65, E66, E90, E91»(ref-202154-S12625613862005102600000) .
  4. Electrical Coolant Pump The coolant pump driven by an electric motor is regulated irrespective of the engine speed. For more information, refer to «N52 ELECTRICAL COOLANT PUMP - E60, E61, E63, E64, E65, E66, E90, E91»(ref-202154-S29822545232005102600000) .
  5. Three-Phase Differential Air Intake Control
  6. Oil Condition Sensor For the N52 engine, the dipstick and its guide pipe are eliminated. The N52 engine has an oil condition sensor. For more information, refer to «N52 ENGINE, OIL CONDITION SENSOR - E60, E61, E63, E64, E65, E66, E90, E91»(ref-202154-S35682165072005102600000) .
  7. Digital Engine Electronics MSV70 The digital engine electronics (DME) control and regulate the engine functions. For more information, refer to «DIGITAL ENGINE ELECTRONICS (N52) - E60, E61, E63, E64, E65, E66, E90, E91»(ref-202154-S04979598002005102600000) .
  8. Cylinder Head Cover Made Of Magnesium
  9. Switchover To Single-Belt Drive
  10. Highly Temperature-Resistant Exhaust Manifold

The following components are involved in the vacuum supply system
