[0003] Traditional cylinder engines are large in size and heavy in weight. General four-stroke engines only work once every two revolutions, and have low thermal efficiency. There is also the Omega1 engine, which produces detonation due to asymmetric ignition: Omega1 is a longitudinally arranged concave and convex double ring (1:1), and the working convex rotor below has only one convex arm, which is asymmetric and ignites once per revolution. The combustion detonation causes large vibrations in a single axial direction and continuous impact on the shaft. The uneven force on the shaft will lead to increased rotational friction and wear.
