    Fuel tank capacity油箱容积


    正确答案: 油箱容积是指一辆车能够携带燃油的体积，通常单位为升（L）。一般油箱容积与该车的油耗有直接的关系，一般一辆车一箱油都能行驶500公里以上，比如百公里10升的车，油箱容积都在60升左右！每个车型的油箱容积是不同的，同类车型不同品牌的车油箱容积也不相同，这个是有各生产厂家决定的。

    单选题
    How does the engine adjust itself to different formulas of fuel?
    A

    By piping in more oxygen for ethanol.

    B

    By sensing the amount of oxygen in a car’s exhaust.

    C

    By burning in a less-than-optimal mode.

    D

    By stopping and checking the fuel tank.


    正确答案： C
    解析：
    从录音中提到的“The new technology works by “sniffing” the amount of oxygen in a car’s exhaust”，可知这项新技术通过感知汽车废气中氧的含量来进行调整。
    【录音原文】
    Petrol burns best with an air-to-fuel ratio of around 14:1. This means that, for every kilogram of fuel burnt, all of the oxygen in 14 kilograms of air will be consumed. Ethanol, though, requires an air-to-fuel ratio of 9:1. The new technology works by “sniffing” the amount of oxygen in a car’s exhaust. If too much or too little of the gas is sensed, it indicates that the fuel is burning in a less-than-optimal way, and thus that the air-to-fuel ratio is wrong. A signal is then sent to the engine to tweak the ratio appropriately.
