Brief description of components
The engine control system of the V8 engine is described for the E65.
With the digital engine electronics (DME) on the N62TU, the following sensors supply signals to the DME control unit:
-
2 eccentric shafts
The eccentric shaft sensor records the position of the eccentric shaft for the Valvetronic. The eccentric shaft
adjusts the camshaft so that the optimum valve lift for the inlet valve is achieved regardless of operating
condition (infinitely adjustable valve lift at intake).
The eccentric shaft is adjusted by the Valvetronic actuator. The eccentric shaft sensor is equipped with 2 angle
sensors which operate independently of one another. For safety reasons, 2 angle sensors are used with
opposed maps. Both signals are digitally transmitted to the Valvetronic control unit.
-
2 inlet camshaft sensors and 2 exhaust camshaft sensors
The valve gear is equipped with variable camshaft control (double VANOS) for the inlet and exhaust camshaft.
The 4 camshaft sensors record camshaft adjustment. To this end, a camshaft sensor gear is fixed to the
camshaft. The camshaft sensor works according to the Hall effect. The integrated supply module supplies
voltage to the camshaft sensors.

Power supply from front power distributor in junction box

Accelerator pedal module
The accelerator pedal module identifies the position of the accelerator pedal.
Using this information, the DME control unit calculates the required position of the Valvetronic or the throttle
valve while taking other criteria into account. The accelerator pedal module is equipped with 2 independent Hall
sensors.
These Hall sensors each emit a voltage signal corresponding to the current accelerator pedal position. For
safety reasons, two Hall sensors are used. The two Hall sensors supply a signal proportional to the position of
