    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.

    Abstract: An internal combustion engine with a braking system comprising a rocker lever, a rocker lever valve and a biasing member selectively preventing contact between a brake lift portion of a cam and a cam follower supported by the rocker lever. Fluid pressures in a first fluid circuit and a second fluid circuit selectively actuate the rocker lever valve to open an exhaust valve and cause brake events.
