    Abstract: A method of assembling a valve driving mechanism, having a variable valve timing unit incorporated in a cylindrical mounting base, to a dual overhead camshaft engine. The engine has camshafts which are rotatably connected by camshaft gears. The method includes the initial step of mounting one camshaft gear, maintained at a predetermined angular position relative to the other camshaft gear attached to the other camshaft, and a lock nut on the one camshaft. Subsequent steps include first adjusting the angular position of the mounting base relative to the one camshaft gear and then the angular position of the variable valve timing unit relative to the one camshaft, and fastening the one camshaft gear to the mounting base by the lock nut and, simultaneously, the variable valve timing unit to the one camshaft.

    Abstract: An improved engine construction is disclosed having a valve train including valves and corresponding valve stems for controlling the intake and exhaust ports, cams for imparting reciprocating motion to the valves by way of the valve train, and a valve spring for biasing each valve toward its closed position and the valve train into tracking relation with the cam. The only element of the valve train coupling a cam to a stem is a cam follower with a depression for receiving the corresponding stem end and a cam engaging surface opposite the depression with the cam follower being held captive intermediate the stem and cam solely by the spring biasing of the stem toward the cam and the engagement of the stem end and the depression. A feature of the engine resides in a combination crankcase breather mechanism and oil fill cap which due to its remote location from the engine crankshaft as well as the tortuous air flow path through the cap to the atmosphere minimizes the egress of oil from the engine through the breather mechanism.

Another feature of the engine resides in the engine block casting which includes an exhaust gas passageway extending from an engine cylinder and including near the end thereof remote from the cylinder an enlarged cavity which defines at least a part of a muffler shell. A further feature of the engine resides in a combination crankcase breather mechanism and oil fill cap which due to its remote location from the engine crankshaft as well as the tortuous air flow path through the cap to the atmosphere minimizes the egress of oil from the engine through the breather mechanism.

    Abstract: Counterrotating cam and follower apparatuses (C-CAFA) capable of converting reciprocating to rotational motion, and visa versa, utilizing counterrotating cams cooperating with at least one reciprocating cam follower. Apparatus cam counterrotation is ensured to be synchronously timed without necessity of prior art stationary geartrains, by and through apparatus cam follower(s) combining with counterrotating cam surfaces acting as moving follower constraints, provided that disclosed structural limitations, including those regarding cam and follower surface interface engineering slop, multiple degree of freedom cams, rotating and reciprocating follower(s), and electromechanical limitations are met when specified. Optional apparatus usages include reciprocating mass balancer, differential to reverse and or multiply shaft rotations, and apparatus combinations with connecting rods, pistons, cylinders, and or engines. “Adequacy of Constraint and Newtonian Force Analysis, Cam and Follower Surface Kinematical Analysis, and Electromagnetic Cam Analysis” are applied to various disclosed embodiments to teach making, using, and correlation of disclosed apparatus structure to function.
