ABSTRACT:
A novel internal combustion cycle and internal combustion engine operating thereon. Expansion of the hot combustion gases is controllably achieved in a primary combustion/expansion chamber and a secondary expansion chamber in a manner to reduce engine exhaust pressures to essentially atmospheric or below. The chambers are defined by two members movable with respect to each other within an engine block volume. Porting and fluid flow control is accomplished through the motion of the moving members. Embodiments include the use of a suction chamber which achieves subatmospheric exhaust pressures and which, in conjunction with a pressure-pumping chamber, achieves a "push-pull" effect on the fluid in the engine. Unique porting of the fuel/air mixture is provided and it includes, if desired, means to vary the fuel/air ratio during the cycle. The engine of this invention exhibits performance characteristics associated with the usual four-stroke cycle engines.
