This chamber contains a slightly eccentric cylinder which can be rotated to make either the upper or the lower slots bigger.

You have to mix oil into the gas in a two-stroke engine because the holes in the cylinder wall prevent the use of rings to seal the combustion chamber.

在二冲程发动机中你必须混和燃料和气体，因为气缸壁上的孔阻止使用活塞环密封燃烧室。

When the cylinder moves backward, the piston is driven to travel backward and generates negative pressure in the front chamber of the cylinder.

当气缸向后运动时，拉动活塞向后，料缸前腔产生负压。

It works by forcing fuel directly into the combustion chamber of each cylinder to mix air and gas simultaneously at the point of combustion, rather than mixing air and gas in a separate chamber like more conventional engines.

The EPA pulled off the feat by sharply increasing the amount of oxygen-poor exhaust that is recirculated into the combustion chamber and increasing the pressure of the fuel being forced into the cylinder.
