Economical and dynamic: The CAM phasing system is an element of the variability of the valve mechanism, helping to progressively reduce fuel consumption and emissions. They optimize valve timing over the wide load and speed range of the engine, thus also increasing power and driving pleasure. Belt and chain drive systems can be used to adjust two camshafts, two camshafts synchronized, or two camshafts independent of each other. Schaeffler's electromechanical CAM phaser adjusts the camshaft more quickly and accurately to suit the appropriate engine operating conditions. Its function is not affected by temperature and engine oil pressure, response speed is fast. With electromechanical help, the camshaft can be adjusted at a speed of 600 degrees of crank Angle per second. The increased regulatory range enables a modern, efficient combustion process concept.
