高辛烷值燃料是一种具有高抗爆性的燃料，系含有高辛烷值的烃类（如异构烷烃和芳香烃）或加有抗爆剂、抗爆组分（如四乙基铅、甲基叔丁基醚等）的燃料，如高辛烷值汽油等。在汽油机中燃烧时可经受较高的压缩比而不致发生爆震，从而得到较高的热效率。
结果发现，高辛烷值燃料异辛烷和高十六烷值燃料正庚烷的混合能够有效控制HCCI燃烧相位和燃烧程度。
The simulation suggested that the mixing with high-cetane fuel and high-octane fuel can influence the combustion phase and cylinder pressure in HCCI combustion.
通过理论分析和试验研究，探索出多种比较理想的轻油高辛烷值调合剂，开发了多种以轻油为基础油的火花点火发动机代用燃料。
Through the theoretical analysis and test, some satisfactory additives with high octane value to light oil were studied, and alternative fuels based on light oil were developed.
将低辛烷值直馏馏分、热裂化或催化裂化重石脑油改质为高辛烷值组分用于车用或航空燃料调合或石油化工的连续过程。
A continuous process to upgrade low-octane virgin, thermal, or heavy catalytically cracked naphthas into high-octane components for motor or aviation fuel blending or petrochemical usage.
