Camshaft Sensors

Camshaft Sensors: The camshaft sensors (Hall effect) are mounted through the cylinder head cover. There are two sensors per cylinder head to monitor the intake and exhaust camshaft positions. The sensors monitor the impulse wheels attached to the ends of the camshafts.




The chart below shows the Bi-VANOS unit camshaft adjustment possibilities. The valve lift adjustment has also been incorporated.

The special feature of Valvetronic is that the air mass drawn in the cylinders can be easily determined by the valve lift and closing time. The air mass can then be limited, thus the term "load control".

With the help of VANOS, the closing point can be easily selected within a defined range. With valve lift control, the opening duration and cross section of the valve opening can also be easily selected within a defined range.
