Independent rotary valve engine

A method for controlling an independent rotary valve engine, comprising:

• installing an intake rotary valve into a first channel of a cylinder head;
• installing an exhaust rotary valve into a second channel in the cylinder head, wherein the second channel is parallel to the first channel;
• connecting a bidirectional servo motor on an engine crankcase;
• connecting a pulley to a servo motor shaft of the bidirectional servo motor and a first end of an inner shaft of the intake rotary valve;
• connecting, by a sprocket and chain mechanism, a crankshaft located in a bore in the engine crankcase to an outer sleeve of the intake rotary valve and to the exhaust valve;
• connecting, by a connecting rod, a piston located within a combustion chamber of a cylinder block to the crankshaft;
• generating, by an engine control unit operatively connected to the spark plug and the servo motor, spark timing signals;
• combusting, with a spark plug located within the cylinder head and operatively connected to the combustion chamber, a fuel mixture in the combustion chamber,
• receiving, by the engine control unit, an engine speed requirement;
• determining, by the engine control unit, a wide-open throttle position and an intake valve closing angle based on the engine speed requirement, and
• generating, by the engine control unit, variable valve timing signals;
• receiving, by the servo motor, the variable valve timing signals;
• and
• rotating, by the servo motor, the servo motor shaft in one of a clockwise direction and a counterclockwise direction based on the variable valve timing signals.
