Abstract:
An internal combustion engine, comprising:at least one housing having an inner circumferential surface; a crankcase; a crankshaft extending from said crankcase; at least one cylinder positioned in said housing having its top portion rotatable substantially along said circumferential surface, said cylinder having a chamber and a piston movable longitudinally therein, a piston rod connecting said piston and extending from said cylinder to movably mount to said crankshaft so that said cylinder is rotatable about said crankshaft; at least one exhaust port formed in said housing to effect a passageway from the inside to the outside of said housing; at least one opening formed in said cylinder to enable gases in the chamber of said cylinder to be evacuated therefrom; and at least one channel formed at said cylinder through which fuel is fed into said chamber of said cylinder via said crankcase in an amount that relates to the positioning of said piston in said chamber; wherein when said cylinder is rotated to a particular portion along said circumferential surface, exhaust gases resulting from combustion in said chamber of said cylinder are evacuated through said one opening of said cylinder and said exhaust port of said housing to the outside of said housing.
