Variable Lift Control Motors

VDO Sensors and VDO Motors e.g. for the Valvetronic System

With help of the Valvetronic System the vehicle power is more direct and increased. On the other hand the consumption is reduced by up to 10% within the gasoline 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 functionalities like emergency operation.

The high-precision VDO Motors adjust continuously the eccentric shaft of the system. Via the eccentric shaft and the 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 enginemanagement.
