Abstract:
A two-stroke internal combustion engine, having at least one cylinder with a piston mounted therein for reciprocal motion between a top position and a bottom position, wherein each said cylinder has multiple one-way air intake valves above the top of said cylinder and arranged in any pattern within a single replaceable unit, to allow air into the top of said cylinder, and at least one exhaust port at a lower position just above said bottom position of said piston, and a blower arranged to force air into said cylinder via each said intake valve as the piston moves around said bottom position, said blower not supplying enough pressure to keep each said intake valve open during upward motion of said piston, such that during upward motion of said piston, compression occurs within said cylinder, and such that during downward motion of said piston said blower forces air into said cylinder via each said intake valve once each said exhaust port is uncovered by said downward motion, and out of said cylinder via each said exhaust port.
