Eaton’s cylinder-deactivation (CDA) technology increases the exhaust temperature at low load to allow NO x aftertreatment systems to quickly reach peak efficiency range of 250 °C – 400 °C. Hydraulic lash adjusters can also support cylinder deactivation. CDA is just one of Eaton’s variable valve actuation (VVA) technologies.

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.
