ABSTRACT:
A valveless four-stroke internal combustion engine employs an intake piston and an exhaust piston that reciprocate within intake and exhaust cylinders disposed adjacent the combustion chamber of the engine. A power piston reciprocates within a cylinder that defines a portion of the combustion chamber. An intake port opens into the intake cylinder, and an exhaust port opens into the exhaust cylinder. Upon reciprocation of the intake and exhaust pistons, the exhaust ports will be covered and uncovered. By coordinating movement of the intake and exhaust pistons with reciprocation of the power piston, a combustible fuel-air mixture will be drawn into the combustion chamber, ignited, and exhausted. The timing and extent of movement of the intake and exhaust pistons can be controlled by a crankshaft or cams.
