Claim 1:
2. The apparatus of claim 1 for converting reciprocating linear motion to rotational motion for a four-stroke internal combustion engine, wherein:
the sliding member is a piston constrained to reciprocate linearly within a hollow cylinder of an engine block, the piston having a piston longitudinal axis;
the connecting member is a piston rod rigidly coupled to the piston at a first end of the piston rod, the piston rod having a piston rod longitudinal axis aligned with the piston longitudinal axis;
the cam, the cam shaft and the lip function as a crank shaft of the four-stroke internal combustion engine, the crank shaft having an axis of rotation intersecting with and perpendicular to the piston longitudinal axis, and
the pin assembly engages the lip of the crank shaft and is configured to rotate the crank shaft as the piston reciprocates within the cylinder.
