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.
這導(dǎo)致偵測(cè)敲擊或聲音，剝奪了權(quán)力的發(fā)動(dòng)機(jī)，同時(shí)，不加制止，造成嚴(yán)重的發(fā)動(dòng)機(jī)損壞。爆震可能與相應(yīng)的辛烷值淘汰。
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.
這樣，依照實(shí)驗(yàn)方法，如果匹配的參考混合物由15%的正庚烷和85%異辛烷組成，那么按照所用的實(shí)驗(yàn)方法，對(duì)比實(shí)驗(yàn)樣本的辛烷值就是85 。

The higher the octane number, the greater the resistance to preignition making a higher compression ratio possible.

a number showing the quality of petrol by representing how well and with how much power it can make an engine work

a measure of the quality of a petrol expressed as the percentage of isooctane in a mixture of isooctane and n-heptane that gives a fuel with the same antiknock qualities as the given petrol
