An Asian automaker has awarded Rheinmetall Automotive subsidiary Pierburg GmbH a contract to develop a variable valve control system. Known as the UpValve, the system will be installed in a supercharged four-cylinder gasoline-powered engine, designed in cooperation with Pierburg. Compared to previous solutions, UpValve has been optimized with regard to high-speed performance, package, and responsiveness. In addition, the new system enables demand-driven cylinder deactivation. The new valve control system can improve fuel efficiency by up to 5%. Production is slated to begin in 2019.
