Eaton Late Intake Valve Closing (LIVC) allows improving engine efficiency & help thermal management

Late Intake Valve Closing allows improving the efficiency of the engine, contributes to aftertreatment thermal management at partial loads and enables higher compression ratios. In the Eaton LIVC system, a standard intake rocker is combined with a switchable rocker. While the standard rocker realizes the regular intake valve lift, the switchable LIVC rocker runs on a secondary cam with increased duration. When the LIVC rocker is active, the valve closing motion is controlled by secondary cam and therefore is delayed. For more
