Publication number: US20220025787A1
Application number: 17/496,865

Abstract:
A system for timing a crankshaft and a camshaft in an internal combustion engine having a cylinder head structure with a timing pin hole and a camshaft cavity. The camshaft has a first opening that extends from an outer annular wall of a first shaft towards a longitudinal axis. A cam bushing having a bushing clearance hole is inserted into the camshaft cavity and the camshaft is assembled with the cam bushing and cylinder head structure to align the bearing clearance hole with first opening of the camshaft. A timing pin is inserted through the timing pin hole, bushing clearance hole, and first opening of the camshaft to position the camshaft in a camshaft timing position. The crankshaft is rotated to a crankshaft timing position either before or after the camshaft is rotated for setting a static timing of the crankshaft and camshaft, and the timing pins are removed.

Publication number: US20220025825A1
Application number: 17/449,992

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.
