ABSTRACT:
Novel internal combustion engines of the swing beam type incorporate an improved construction utilizing a Rapson-slide motion and also are derived from two degree-of-freedom mechanisms for controlling the displacement of the piston as a function of crankshaft displacement and of the displacement of a control shaft. The control shaft either operates at an average speed which is preferably a prescribed ratio of crank speed, thereby yielding an improved thermodynamic cycle (such as the Atkinson cycle in the case of a four-stroke engine) and cycle timing, or functions as a lever for obtaining variable stroke operation. The mechanism can also incorporate a variable compression ratio feature.
