Abstract: A twin cylinder engine, includes a pair of cylinder members mounted to mounting surfaces of a crankcase, and cylinder heads mounted to the cylinder members. The cylinder members are modular components, which may be pre-assembled with components of the valve train as packaged units before the cylinder members are attached to the crankcase. Each cylinder member rotatably supports a cam gear which extends into the crankcase for driving engagement with the crankshaft. The cylinder members may be configured for either side valve-type (“L-head”), or overhead valve-type (“OHV”) engines, and the cylinder members may also be used in single cylinder engines.

Abstract: The valve drive mechanism is particularly suitable for internal combustion engines of motor vehicles. The mechanism has at least one driven cam element and a valve control member which is moved (translationally or rotationally) by the cam element. The cam element is rotatingly mounted in a flexible surround element which is connected to the valve control member in a plane orthogonal to the axis of rotation of the cam element. The surround element can be reversably extended, such as elastically extended, to enable a variation in the resulting valve lift.

Abstract: A decompression device for a four-stroke engine, which drives the inlet valve and the exhaust valve by using the profile surface of a cam and rocker mechanism. This cam includes a guiding recess provided on the side surface thereof and a slot provided on the cam profile surface communicating with the guiding recess. The decompression device further includes a centrifugal member, received within the guiding recess, having a projecting portion and being rotatable and movable within the guiding recess, and a spring having two ends fixed to the cam and the centrifugal member. By the cooperation with the spring and the guiding recess, when the cam is rotated at a lower speed, the projecting portion of the centrifugal member projects through the slot to the outside of the cam profile surface under the action of a weaker centrifugal force, thereby lifting the second follower so as to open the exhaust valve before the TDC of the compression stroke, and when the cam is rotated at a higher speed, the projecting portion of the centrifugal member sinks into the inside of the cam profile surface under the action of a stronger centrifugal force, thereby closing the exhaust valve.

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. The spring biasing is provided by a coiled wire spring having outwardly extending legs each of which engages a corresponding stem to urge the valves toward their closed position. The bight or coiled portion of the spring is held in a relatively fixed position by a portion of the engine casting.

Abstract: A system for varying valve timing; i.e. the rotational angle of the crankshaft during which an intake or an exhaust valve of a cylinder of a reciprocating internal combustion engine is open which results in varying valve overlap, and for varying valve lift of such intake and exhaust valves. A desmodromic cam and cam follower convert rotation of a cam shaft to reciprocating rotation, or oscillation, of the cam follower. The reciprocating rotation of the cam follower is converted by the interaction of a secondary cylindrical cam, a cylindrical control ring, and a reciprocating member to linear motion of the reciprocating member which reciprocating member is operatively connected to a poppet valve. Timing and lift of the reciprocating member and valve are variable over predetermined limits as a function of engine rpm and load by rotation of the cylindrical control ring. Each valve train positively closes as well as opens its associated valve.
