Abstract
An engine braking system includes a camshaft, a follower, an exhaust armature, a lever, and a hydraulically actuated piston. The camshaft includes at least one cam. The cam has a lobe and a brake bump. The follower engages the cam. The exhaust armature is coupled to the follower. The lever is coupled to the exhaust armature. The hydraulically actuated piston moves the lever. Hydraulic actuation of the piston causes a change in lash distance between the cam and the follower. In an engine brake mode, the follower contacts the cam throughout rotation of the cam.
