The effects of port injected n-heptane equivalence ratio and iso-octane direct injection timing are investigated experimentally and numerically. The results indicate that the combustion mode of iso-octane is dependant on the iso-octane direct injection timing corresponding to the stage of n-heptane HCCI combustion. In case of direct injection before the low temperature reaction of n-heptane, premixed combustion of the iso-octane occurs. In case of direct injection at the NTC period or the initial high temperature reaction stage of n-heptane, the iso-octane mainly undergoes premixed combustion.

进一步采用进气道预喷正庚烷，缸内直喷异辛烷，在没有火花点火和热EGR的辅助下利用预喷正庚烷HCCI燃烧产生活化热氛围的热作用和化学作用引燃缸内直喷高辛烷值燃料异辛烷，系统研究了不同预喷正庚烷当量比和缸内直喷时刻对直喷异辛烷燃烧模式、发动机效率和排放的影响，并用三维CFD耦合化学反应动力学对其燃烧过程进行数值模拟。

It was found that more branch-2 olefin and C5~C6 isoparaffin molecules existed in MIP naphtha. The cause of MIP naphtha having higher octane number and less octane loss during hydrotreating could be explained by the octane model of C6 hydrocarbons quantitatively.

通过对MIP和FCC汽油组成分析，发现MIP汽油组成含有较多的多支链烯烃、异戊烷和异己烷，基于碳六烃的辛烷值模型，可以定量地解释MIP汽油辛烷值高和加氢MIP汽油辛烷值损失低的原因。

The addition of iso-octane extends the knocking limit in equivalence ratio somewhat, however the knock occurrence mainly depends on the total concentration of mixture. Although the operation range in equivalence ratio becomes narrow with the increasing of iso-octane, the maximum load is improved 80% by n-heptane/iso-octane controlled real-time in contrast with the HCCI fueled with n-heptane only.

结果表明：混合燃料HCCI着火以及燃烧相位主要取决于正庚烷实际的燃空当量比；异辛烷的加入对爆震当量比界限有所拓展，但HCCI爆震主要与混合燃料总当量比有关；随着辛烷值比例的提高，导致HCCI运行范围变窄，但是实时调控证明相对纯正庚烷，混合燃料的HCCI燃烧最大负荷提高了80%。

octane number：辛烷值

燃料的抗爆震X是以辛烷值(Octane Number)来表示,通常分子构造简单、碳数多、炼长者的抗爆震X优秀,而选用辛烷值较高的汽油是减少爆震发生的最直接方法. 汽油辛烷值的选用必须与引擎的缩比配合,理论上压缩比8~9用辛烷值92~95的汽油,
