Empa team develops electrohydraulically actuated cam-less valve train; up to 20% fuel savings at low load

Green Car Congress

The valve train is the “respiratory organ” of combustion engines: it manages the aspiration of fresh air and the discharge of exhaust gases (gas exchange). The basic principle of the valve train—for both intake and exhaust side—is an asymmetric hydraulic pendulum, which can be described as a mass-spring-system.
