Task

Improving idle speed, boosting torque and power output in the mid/upper engine speed/load range.

Design/function

The camshaft solenoid which is operated by the engine control module, is attached to the camshaft adjuster. The position of the inlet camshaft is altered by rotating the camshaft adjuster to "advanced" (large valve overlap) or to "retarded" (slight valve overlap - basic position).

Example of engine 120: The adjustment range of the camshaft adjuster is approx. 32° crank angle. The figures relate to drive position engaged and

moderate engine load:
