The hydraulic valve clearance regulator ensures that the valve mechanism operates without any valve clearance, thus ensuring constant valve timing throughout the engine's service life. Schaeffler Automotive develops and produces a variety of valve mechanism assemblies with hydraulic valve clearance adjustment for engines with overhead camshafts or CAM blocks, thus making a significant contribution to reducing operating costs and emissions. Schaeffler Automotive Technologies, derived from developments in the passenger car sector, offers customised switchable valve mechanism components and systems that contribute to the advancement of reducing fuel consumption and emissions and ensuring the required temperature for exhaust post-treatment.
