octane rating

基本解釋

The gasoline label number is classified by the octane rating, which means the content of the octane.
汽油的標(biāo)號(hào)是通過(guò)它的辛烷值來(lái)劃分的。辛烷值代表汽油中辛烷的含量。
Another problem is that existing petrol engines cannot take advantage of the much higher octane rating.
另外一個(gè)問(wèn)題是現(xiàn)有的汽油引擎無(wú)法利用更高辛烷值的優(yōu)勢(shì)。
Some areas in America has prohibited MTBE that is gasoline octane rating's additive,and more areas will be possibility.
甲基叔丁基醚(MTBE)作為汽油辛烷值的改進(jìn)劑已在美國(guó)部分地區(qū)受到禁用,并有大規(guī)模禁用的可能性。
The test mixture by which a gasoline's octane rating is judged combines 2,2,4-trimethylpentane and heptane (87 to 13 percent for “87 octane”).
用以測(cè)定汽油辛烷值的，是2,2,4-三甲基戊烷和庚烷的混合物（辛烷值為87表示兩者比例為87:13）。
However, if it knocks heavily under most driving conditions while you are using fuel with the recommended octane rating, see your authorized dealer to prevent any engine damage.
可是，在使用推薦的辛烷值燃油時(shí)，要是在大部分行駛條件下爆震嚴(yán)重，請(qǐng)找你的福特授權(quán)經(jīng)銷(xiāo)商，避免任何對(duì)于發(fā)動(dòng)機(jī)的損傷。

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
