一种内燃发动机和一种内燃发动机的操作方法
摘要：
一种内燃发动机(10)，包括发动机缸体(12)，发动机缸体限定了具有纵轴A的汽缸(14)。活塞(16)滑动地设置于汽缸(14)内，叶轮(18)设置于汽缸(14)的一端处。叶轮(18)转动地安装在轴(30)上，所述轴延伸出汽缸(14)并通过叶轮(18)的旋转驱动其旋转。发动机进一步包括防旋转结构(20)，以防止活塞绕汽缸纵轴旋转，和设置于活塞面上的引旋叶片(38)，面对设置有叶轮的汽缸端部。通过汽缸中活塞和叶轮之间的燃油燃烧所产生的燃烧气体通过与引旋叶片的作用而打旋，打旋的燃烧气体进而使叶轮旋转。
摘要（英）：

An internal combustion engine (10) comprises an engine block (12) defining a cylinder (14) having a longitudinal axis A. A piston (16) is arranged slidably within the cylinder 14 and an impeller 18 is arranged at one end of the cylinder (14). The impeller (18) is rotatably mounted on a shaft (30), which extends out of the cylinder (14) and which is driven in rotation by rotation of the impeller (18). The engine further comprises an anti- rotation formation (20) to prevent the piston rotating about a longitudinal axis of the cylinder and a swirl-inducing vane (38) arranged on the face of the piston which faces the end of the cylinder at which the impeller is arranged. Combustion gas generated by combustion of a fuel in the cylinder between the piston and the impeller is caused to swirl by reaction with the swirl-inducing vane and the swirling combustion gases, in turn, cause the impeller to rotate.
