Also known as octane number, research octane number, RON, motor octane number, MON, anti-knock index, AKI, pump octane number
standard measure of an engine or aviation fuel's ability to withstand compression without detonating
Octane rating measures how well a fuel can withstand being compressed in an engine without exploding prematurely. Higher octane fuels are more resistant to this detonation, which matters because engines designed for higher octane fuel perform better and more reliably when you use the fuel they require.

辛烷值(英語:Octane Number)是交通工具所使用燃料的抗爆震程度之量測指標(该指标一般常用于描述汽油的性能);辛烷值越高表示抗爆震能力越好。 辛烷值一般是区分不同等级汽油的关键标准,比如中国大陸的98号汽油及台灣98無鉛汽油,均表示其辛烷值为98;但注意各地區加油站的对汽油的标示方法并不统一,在一些国家其出售的汽油的数值不等于常见的研究法得到的辛烷值(如美国),另一些则根本不以数值标示(如德国)。 提高汽油辛烷值的方法包括加入四乙基鉛及甲基叔丁基醚、碳酸二甲酯、(甲基环戊二烯三羰基锰)等。由於鉛是有毒物質,因此大部分國家的油站已不再提供含鉛汽油,僅餘航空汽油仍帶有鉛,而汽車只有在賽車中某些賽事等特殊場合使用。
