Variable Camshaft Adjustment

The camshaft has the task of operating the valves at the right time and in the correct order and to control the gas exchange. The camshaft regulation optimally adjusts the opening times of the valves in all operating conditions. In engines with a double overhead camshaft, the size and positioning of the valve opening overlap can be influenced, enhancing characteristics in full-load and part-load operation.
