Abstract
An added-motion engine braking system selectively operable in an engine braking mode and a drive mode and compatible with providing hydraulic lash adjustment includes an exhaust rocker arm assembly, a main exhaust valve and a brake valve, a valve bridge configured to selectively act on the main exhaust valve and the brake valve and constrained to move parallel to a valve opening direction, a hydraulic lash adjuster disposed on the exhaust rocker arm assembly and configured to automatically compensate for lash between the exhaust rocker arm assembly and the valve bridge; and an engine braking rocker arm assembly configured to selectively act on the brake valve in the engine brake mode, wherein, in a base circle position with the main exhaust valve and the brake valve closed, the valve bridge is configured to preferentially contact the main exhaust valve compared to the brake valve.
