Abstract: An engine compression braking system includes a brake tappet linking an exhaust cam to at least one exhaust valve of an engine cylinder. The brake tappet is connected with a working fluid that selectively activates and deactivates a compression braking mode of operation by selectively engaging and releasing a lash assembly of the brake tappet relative to a housing of the brake tappet.

Abstract: A variable valve timing assembly is provided for extending a duration of an intake valve opening. The variable valve timing assembly includes an intake rocker mounted on a pedestal and operable by a cam lobe to open and close the intake valve. The intake rocker includes a lever extension, and a holding member in the pedestal is lockable in position by a hydraulic circuit in the pedestal to contact the lever extension of the intake rocker and hold the intake valve in the open position. A reset pin in the pedestal is actuatable by the cam lobe to release the holding member to allow the intake valve to close.
