Abstract:
A dual piston compression chamber for two cycle engines comprising:a) a cylinder housing member having an annular recess forming an interior cylinder with a stationary top wall closing off a top of said interior cylinder; b) a plurality of intake ports in said top wall of said cylinder housing member to permit the introduction of a combustible media directly into said interior cylinder; c) at least one exhaust port in said cylinder housing member; d) a primary piston adapted for reciprocating travel completely within said interior cylinder; e) an intake/exhaust piston adapted for reciprocating travel completely within said interior cylinder between said primary piston and said top wall and having a plurality of passageways extending therethrough forming piston ports; f) a one-way valve in each said piston port fully enclosed within said intake/exhaust piston for controlling the directional flow therethrough; g) a one-way valve in each said intake port fully enclosed within said top wall for controlling the directional flow therethrough; h) means for igniting said combustible media; and i) means for regulating the synchronization of said primary piston and said intake/exhaust piston as they travel at differing rates and distances than one another to provide the precise alignment of said pistons with the various ports during the operating cycle thereof.
