Abstract
A valve train arrangement including at least one exhaust valve and a reverse-spring hydraulic lash adjuster (RSHLA) is provided. The RSHLA has a predetermined closing velocity. An engine brake system is configured to engage the exhaust valve, such that: (i) upon activation of the engine brake system, the engine brake system engages the at least one exhaust valve to open the at least one exhaust valve; and (ii) upon deactivation of the engine brake system, the engine brake system disengages the at least one exhaust valve such that the at least one exhaust valve is closed. A deactivation velocity of the engine brake system is less than the predetermined closing velocity of the RSHLA.
