Rotary internal combustion engine

Abstract

Disclosed is a rotary internal combustion engine of which all operations are circular motions and therefore energy consumed for mechanical transmission is reduced and power output is continuous and stable. The rotary internal combustion engine mainly includes an intake-compression chamber, an exhaust-power chamber, and a combustion chamber that has an intake port and an exhaust to communicate with the intake-compression chamber and the exhaust-power chamber, respectively. Two pairs of rotors and rotational valve plates are separately provided in the intake-compression chamber and the exhaust-power chamber to mount around a power output shaft extending through the two chambers, so that the rotors, the valve plates, and the power output shaft rotate synchronously. When the valve plates rotate with valve holes provided thereon separately overlapping the intake port and the exhaust port of the combustion chamber, either compressed air in the intake-compression chamber is compressed into the combustion chamber for combustion, or burned and exploded gas in the combustion chamber is released into the exhaust-power chamber to rotate the power output shaft. The rotary internal combustion engine has simplified peripheral mechanisms and reduced volume while it has increased thermal efficiency and enhanced power output.
