英汉例句

• with lead and mtbe additives now phased out, spiking petrol with a small amount of ethanol raises its octane level enough to prevent the engine from 「knocking」 under load.

  目前铅和甲基叔丁基醚（mtbe）等添加剂被叫停，取而代之的是在汽油中添加少量酒精，这样提升辛烷水平能防止负载中引擎产生爆震。

• thus, if the matching reference blend is made up of 15% nheptane and 85% isooctane, the test sample is rated 85 motor or research octane number, according to the test method used.

  这样，依照实验方法，如果匹配的参考混合物由15%的正庚烷和85%异辛烷组成，那么按照所用的实验方法，对比实验样本的辛烷值就是85 。

• through it, octane value of gasoline, cetane value of diesel oil, aromatics and sulphur contents in fraction oil can be calculated.

  用此方法可以计算汽油的辛烷值、柴油的十六烷值、馏分油中芳烃和硫含量。

• of these, heptane with 7 carbons causes undesirable engine knocking, so refiners try to blend in more smooth-burning octane with 8 carbons.

  7个碳的庚烷引起不明原因引擎抽风。炼油厂尝试混入更多的8个碳的辛烷。

• ethanol’s higher octane rating (around 96 compared with 91 for premium grade petrol) allows them to have a higher compression ratio—and thereby deliver more power as a result.

  乙醇有更高的辛烷值（大约为96，相比而言，优质汽油的辛烷值为91），这能使它们有更高的压缩比——因此，能释放更多的能量。

• never use a higher octane gasoline than your owner「s manual recommends.

  请不要使用比你汽车用户手车上推荐的辛烷含量更高的汽油。

• most users will find one 12-ounce bottle of amsoil octane boost for 15 gallons of gasoline provides the ideal performance increase.

  大多数用户会发现一个12盎司一瓶的amsoil升压辛烷值为15加侖汽油，提供了理想的性能提升。

• by and large, flex-fuel vehicles sacrifice ethanol」s higher octane rating—and accept its poorer fuel economy—so they can also use widely available petrol.

  总之，弹性燃料动力技术的汽车牺牲了乙醇的高辛烷值，接受了更低的燃料经济性，所以它们也能使用随处可得的汽油。

• it causes a knocking or pinging sound, robs the engine of power and, left unchecked, causes serious engine damage. knock may be eliminated with the appropriate octane number.

  这导致侦测敲击或声音，剥夺了权力的发动机，同时，不加制止，造成严重的发动机损坏。爆震可能与相应的辛烷值淘汰。
