Abstract
A crank pin is carried on a planetary gear such that the crank pin traces out a substantially triangular or other path having a relatively long flattened portion. In an internal combustion engine, motorized vehicle or other device in which a piston reciprocates inside a cylinder and fuel is combusted within the cylinder, the crank pin is coupled to the piston, and the movement of the crank pin is timed such that the crank pin travels within the flattened portion of the path during at least some part of the main burning period.
