VDO Sensors and VDO Motors

With help of the BMW Valvetronic System, the vehicle power is more direct and increased. On the other hand the consumption is reduced by up to 10% in a petrol engine.

Within this system the airflow is controlled by the Variable Valve Lift and replaces the Throttle Valve. Nevertheless, a Throttle Valve is still mounted and responsible for other functions such as an emergency operation.

The high-precision VDO Motors adjust continuously the eccentric shaft of the system. Via the eccentric shaft and cam shaft driven rocker arm, the intake valves are variably adjusted. The VDO Sensors exactly control the adjusted angle of the eccentric shaft and report this value to the engine management system.
