汽油的

"The engine uses two fired four-stroke cylinders under high pressure, which alternately exhaust into a low-pressure central expansion cylinder, which, in a fifth stroke, provides a further expansion process on the exhaust gases."

高低压指的是工作流体操作的压力，不是压缩比，中缸只有提供&膨胀&行程，并没有压缩点火燃烧等，因为这是汽油引擎，燃烧在小缸点火爆炸完的瞬间就结束了，排气进到中缸只是在继续减压膨胀，并没有做其他事

The common solution is to expand their respective lineups with ultra-frugal petrol and diesel minicars as well new zero-emissions electric vehicles.

双方共同的解决方案是扩大超低油耗汽油和柴油车系列的阵容并增加新的零排放电动车。

Military units trying to block off the sprawling protest site were attacked by stone-throwing yobs who brought along petrol bombs and firecrackers.

军队尝试着封锁示威者营地的行动遭到持有汽油燃烧瓶和鞭炮的年青示威者的投掷攻击。

Today, exhaust treatment systems in our petrol engines filter out between 95 and 99% of the carbon monoxide, nitrogen oxides and hydrocarbons in the exhaust gases.

今天，我们的汽油发动机中所采用的尾气处理技术可以过滤掉尾气中 95-99%的一氧化碳、氧化氮和碳氢化合物。

Today, exhaust treatment systems in our petrol engines filter out between 95 and 99% of the carbon monoxide, nitrogen oxides and hydro carbon s in the exhaust gases.

今天，我们的汽油发动机中所采用的尾气处理技术可以过滤掉尾气中 95-99%的一氧化碳、氧化氮和碳氢化合物。

In the world, the sulfide content in petroleum is increasing with each passing day.

世界上供应的石油资源硫含量在逐渐增加，同时由于环境问题的突出，对汽油、柴油等石油产品硫含量制定了更加严格的标准。

Now that petrol prices have fallen down to their pre-spike levels and is once again cheaper than diesel, it doesn't make economic sense for Ford to introduce a new diesel engine for the F-150 and thus plans for the oil-burning truck have been delayed.

现在，汽油价格下跌至前扣球水平和再次低于柴油，它不经济意义，福特推出了新的柴油发动机的F - 150 ，因此计划的燃油车已经被推迟。

The result, if all goes well, will be a mixture of hydrocarbons that can be fed into the stage of the oil-refining process just before petrol and diesel emerge from the stills, and at a price that competes with the equivalent chemical mixture produced by traditional methods.

如果一切顺利的话，结果将生产出一种碳氢化合物的混合物，可直接输入到现有炼油厂汽油和柴油从蒸馏锅中生成前的那个提炼阶段，而且可以与传统方式生产的当量化学混合物在价格上相竞争。

It is likely that the popular 1.6-litre petrol engine will continue to be the basis of power for the car in both natural and artificial aspiration.

可能是受欢迎的1.6升汽油发动机将继续根据功率的汽车在自然和人工的愿望。

Over the past few months, the refiners who turn crude into gasoline have absorbed part of the rise in oil prices.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
