汽油燃料液滴加热和蒸发过程的建模研究使用这种燃料的几个近似。这些是准离散模型中使用的准组分以及这些准组分的近似值（替代物I（摩尔分数：83. 0% n-C6 H14 + 15. 6% n-C10 H22 + 1. 4% n-C14 H30）和替代物II（摩尔分数：83. 0% n-C7 H16 + 15. 6% n-C11 H24 + 1. 4% n-C15 H32））。此外，我们还使用了替代物A（摩尔分数：56% n-C7 H16 + 28% iso-C8 H18 + 17%C7H8）和替代物B（摩尔分数：63% n-C7 H16 + 20% iso-C8 H18 + 17%C7H8），最初是基于替代物的点火延迟与汽油燃料的点火延迟的接近性而引入的。液滴半径和温度的预测的基础上的三个准组件和它们的近似（代理I和II）被证明是更准确的预测比使用代理A和B。
Modelling of gasoline fuel droplet heating and evaporation processes is investigated using several approximations of this fuel. These are quasi-components used in the quasi-discrete model and the approximations of these quasi-components (Surrogate I (molar fractions: 83.0%n-C6H14+ 15.6%n-C10H22+ 1.4%n-C14H30) and Surrogate II (molar fractions: 83.0%n-C7H16+ 15.6%n-C11H24+ 1.4%n-C15H32)). Also, we have used Surrogate A (molar fractions: 56%n-C7H16+ 28%iso-C8H18+ 17% C7H8) and Surrogate B (molar fractions: 63%n-C7H16+ 20%iso-C8H18+ 17% C7H8), originally introduced based on the closeness of the ignition delay of surrogates to that of gasoline fuel. The predictions of droplet radii and temperatures based on three quasi-components and their approximations (Surrogates I and II) are shown to be much more accurate than the predictions using Surrogates A and B.
