日本某工程师和教授发明了气缸可旋转的发动机——气缸在固定的机体内旋转。气缸内设一个孔,气缸旋转时,该孔与机体的进气孔和排气孔重合。发动机没有气门。气缸孔靠气环密封。气环与机体壁贴合的程度取决于离心力的大小。试验时采用的发动机 A Japanese engineer and professor invented the cylinder can rotate the engine - cylinder in a fixed body rotation. A hole in the cylinder, the cylinder rotation, the hole and the body of the intake and exhaust coincide. The engine has no valve. Cylinder hole by gas ring seal. The degree of fit between the annulus and the body wall depends on the magnitude of the centrifugal force. The engine used in the test
