Abstract:
Disclosed is a method and system for intermittently operating poppet valves in an internal combustion engine when desired by the selective locking or unlocking of one or more cam lobes with the camshaft. One or more cam lobes, with a small radial clearance, ride on a camshaft such that an engagement mechanism may be activated as desired to lock the cam lobe to the camshaft, thereby activating the respective poppet valve. The cam lobe is prevented from moving axially to ensure correct alignment with a follower. A suitable holding device may be used to ensure the non-activated cam lobes are restrained at a suitable orientation relative to the cam follower.

Claim (Index 1):
A cam driven reciprocating internal combustion engine comprising:\n a cylinder block defining a plurality of cylinders, each said cylinder in mechanical communication with a respective cam driven intake valve and/or exhaust valve; a rotating camshaft in mechanical communication with at least one selectively disengageable cam lobe; said cam lobe that when mechanically coupled to said camshaft, controls the operation of said respective intake valve and/or said respective exhaust valve; at least one coupler that selectively couples and decouples said rotational force of said camshaft to said at least one respective cam lobe; said at least one cam lobe that is rotationally disengaged and uncoupled from said rotation of said camshaft in a first mode thereby deactivating said respective valve, and said cam lobe that is rotationally engaged and coupled with respect to said rotation of said camshaft in a second mode thereby activating said respective valve; and, a controller that sends a signal to said at least one coupler to rotationally disengage said respective valve during operation of said internal combustion engine.
