阅读说明：本技术 圆周气道发动机 (Circumferential air passage engine ) 是由 蒙毓江 于 2021-08-18 设计创作，主要内容包括：本发明公布了一种发动机,属于机械技术领域。本发明中,高压气体沿工作气道膨胀做功,推动定阀运动,带动相关部分转动,从而输出动力,因此本发明称为“圆周气道发动机”。工作过程是：喷气→点火→做功(同时排气)。(The invention discloses an engine, and belongs to the technical field of machinery. In the invention, high-pressure gas expands along the working air passage to do work, and pushes the fixed valve to move, so that the related part is driven to rotate, and power is output, therefore, the invention is called as a circumferential air passage engine. The working process is as follows: jet → ignition → work (simultaneous exhaust).)
