In brief, when considering the difference between gasoline and kerosene and diesel, the real difference lies in their boiling points, which are different from each other. The three petroleum products are separated by heating crude oil to different temperatures. There, different hydrocarbon chains are separated and pulled out depending upon their boiling points.

什么是汽油?

Gasoline is a liquid fuel that we use mainly in spark-ignited内燃机。它是透明的液体和石油衍生的燃料。因此，这种燃料中的主要成分是有机化合物，即烃。同样，汽油含有轻质碳氢化合物的混合物，并添加了一些添加剂，以增强理想的特性。而且，原油或石油来自地球作为自然来源。我们可以通过开采地下地下水平来获得原油，并通过油脂产生类似汽油的燃料。通常，42加仑的原油可产生约19加仑的汽油。

通常，该燃料中烃的混合物包含C4至C12的分子。因此，这种燃料包含由4个碳原子组成的碳氢化合物，其化学结构中的12个碳原子。因此，这种燃料包含相对轻的碳氢化合物。它是这些分子的均匀混合物，包括石蜡，烯烃和环烷烃。但是，这些化合物的实际成分取决于炼油厂的加工单元，原油饲料和汽油等级。此外，如果我们正确存储，优质汽油稳定了六个月。

什么是煤油？

Kerosene is a liquid fuel that derives from petroleum that has wide applications in industry and household needs. It is a mixture of combustible hydrocarbon compounds. The synonyms that we use for the same fuel are paraffin oil, lamp oil and coal oil. Moreover, it is useful in powering jet engines, rocket engines and as a cooking and lighting oil.

Furthermore, manufacturers use coloured containers to store this fuel in order to distinguish it from gasoline which is much more flammable and volatile. Or else, they just dye the product. It is a low viscosity, transparent liquid fuel. We can obtain it from fractional distillation of petroleum oil at around 150 and 275 °C temperatures. Typically, this fuel contains hydrocarbons containing carbon atoms ranging from 10 to 16. Therefore, the major organic molecules in this fuel are a saturated straight chain and branched chain alkane along with cycloalkanes. Moreover, Olefins are usually not present at more than 5% by volume.

What is Diesel?

Diesel is a liquid fuel that we use in diesel engines. It is because diesel fuel ignition takes place without any spark. The ignition is a result of compression of the inlet air mixture and then injection of fuel. Hence, the diesel engines have a high thermodynamic efficiency and fuel efficiency. The diesel is not essentially petroleum-derived fuel. Furthermore, there are synthetic forms, biodiesel, diesel obtained from the hydrogenation of fats and oils, etc.

但是，最常用和广泛使用的形式是石油衍生的柴油形式。它包含一个重量级的碳氢化合物混合物，每个分子的含量为8至21个碳原子。这种碳氢化合物混合物来自于200°C至350°C下石油油的分数蒸馏。

汽油和煤油和柴油之间有什么区别？

Gasoline is a liquid fuel that we use mainly in spark-ignited internal combustion engines while kerosene is a liquid fuel that derives from petroleum which has wide applications in industry, powering jets and rockets and even in household needs whereas diesel is a liquid fuel that we use in diesel engines. Accordingly, the difference between gasoline and kerosene and diesel is mainly in their major applications. Another important difference between gasoline and kerosene and diesel lies upon their boiling points because the boiling point is the key to the separation of these fuel fractions from petroleum oil via fractional distillation. Gasoline has a low boiling point while kerosene has a moderate boiling point whereas diesel has a high boiling point. However, the boiling points vary depending upon the hydrocarbons present in the fuel, crude oil feed, etc.
