还有现在的港口第二上方的每个气缸连接到新的排气口上多方面的。
There is also now a second port in the top of each cylinder that connects to the new exhaust ports on the manifold.
同时，活塞使进气口露出，受压缩的可燃混合气开始进入气缸。
At the same time, the intake port, now cleared by the piston, begins to deliver air-fuel mixture, under pressure, to the cylinder.
在二行程发动机中，活塞起到阀门的作用，当活塞接近下止点时，使气缸壁上的进排气口打开。
In the two-cycle engine, the piston ACTS as a valve, clearing valve ports in the cylinder wall as it nears BDC.
活塞顶部的形状使进入气缸的可燃混合气向上运动，这样有助于扫气，引导燃烧过的废气向上运动并从排气口排出。
The top of the piston is shaped to give the incoming mixture an upward movement. This helps to sweep the Burned gases ahead and out through the exhaust port.
绕道港口切割成气缸仅低于排气口和转移的渠道，形成由一个空心之间的钢瓶和铝间隔环。
The bypass ports are cut into the cylinder just below the exhaust ports and the transfer channels are formed by a hollow between the steel cylinder and the aluminum spacer ring.
