In fact, each unit volume of fuel combustion, about 1 million to unit volume of air through the filter.

事实上，每单位体积的燃油燃烧时，约需要有1万单位体积的空气通过滤清器。

It is known that higher Pressure can accelerate combustion reaction, strengthen heat transfer, reduce boiler volume, and even lower boiler cants.

增压可加速燃烧反应、强化传热，从而缩小锅炉体积，甚至可降低锅炉造价；

Valves are clustered near the center of the bore to minimize combustion chamber volume and to provide ample squish area.

阀门是聚集在附近的孔中心，以尽量减少燃烧室量，以及提供足够的果酱领域。

Some are rotary, with as many as four small geared elliptical rotors creating and then foreclosing combustion chamber volume.

Nitrogen is separated from oxygen before combustion, thereby reducing the volume of exhaust gas and making the exhaust easier to treat by preventing the formation of polluting nitrogen oxides.
