Abstract:
A stratified charge two cycle engine comprising:a cylinder having an upper end and a lower end with a head at said upper end and fuel and air intake ports at said lower end; at least one spark plug mounted in said head; a sleeve in said cylinder having an upper end and a lower end; said cylinder having exhaust ports at said upper end which are covered and uncovered by the upper end of said sleeve; a piston in said sleeve and connected to a crank shaft; a first exhaust manifold at one side of said cylinder at said upper end thereof adjacent one of said exhaust ports in said cylinder and having first exhaust gas throttle valve means associated therewith; at least a first and a second fuel and air intake manifolds at one side of said cylinder and at said other side of said cylinder in communication with first and second fuel and air intake ports in said cylinder; throttle valve means in each intake manifold; a reed cage assembly in each intake manifold adjacent the associated intake port for injecting a fuel and air mixture into said cylinder; control means for controlling the injection of fuel and air mixture into said cylinder so that fuel and air mixture is injected into said cylinder through only one intake port when the engine is operating from zero to one half full load; and an operating connection between said crank shaft and said sleeve for causing reciprocation of said sleeve relative to movement of said piston to open and close said exhaust ports and said air and fuel intake ports in said cylinder.
