  原油是各种油和渣油(沥青)的混合物。精炼厂精馏净化后,蒸馏设备生产产品所需温度由低到高依次为塔顶气(类似天然气)、汽油、煤油、柴油、渣油(沥青),产品密度依次增大。

  Crude oil is a mixture of various kinds of oil and residual oil (asphalt). After distillation and purification in the refinery, the temperature required for the distillation equipment to produce products is from low to high, followed by tower top gas (similar to natural gas), gasoline, kerosene, diesel oil, residual oil (asphalt), and the product density increases in turn.

  在实践中,大多数炼油厂将煤油产品与一半汽油和一半柴油混合,但不生产煤油产品。

  In practice, most refineries mix kerosene products with half gasoline and half diesel, but do not produce kerosene products.

  汽油燃点低,可由活塞点燃,汽油机体积小,重量轻,所以动力小的汽车如汽车、摩托车、三轮车都是用汽油机。汽油标签常用有92 #、95 #、98 #等,它指的是相对燃烧稳定性,标签越大,爆炸性越好。

  Gasoline has a low ignition point and can be ignited by a piston. Gasoline engines are small in size and light in weight. Therefore, automobiles with small power such as automobiles, motorcycles and tricycles all use gasoline engines. There are 92, 95 and 98 gasoline labels, which refer to the relative combustion stability. The larger the label, the better the explosiveness.

  柴油燃点高,需要用压缩高温空气点火。然而,高温高压决定了柴油发动机相对较重,但柴油发动机可以提供大量的动力。因此,柴油机主要用于船舶、起重机、拖拉机、卡车和坦克等大功率机械。柴油的一般编号为0 #,-10 #,表示柴油的凝固点温度。

  Diesel fuel has a high ignition point, so it needs to be ignited with compressed high temperature air. However, the diesel engine is relatively heavy because of high temperature and high pressure, but it can provide a lot of power. Therefore, diesel engine is mainly used in ships, cranes, tractors, trucks, tanks and other high-power machinery. The general number of diesel oil is 0 ? - 10 ?, indicating the freezing point temperature of diesel oil.

  煤油在前两者之间有一个燃点,可以通过一个电动活塞点燃,燃烧稳定。在解放初期,大多数农村地区使用煤油。另一方面,航空煤油需要经过特殊的净化和混合。它的燃烧稳定性非常高,在飞机的发动机中燃烧,然后迅速喷出,为飞机提供足够的动力。

  Kerosene has a burning point between the first two, which can be ignited by an electric piston, and the combustion is stable. In the early days of liberation, kerosene was used in most rural areas. On the other hand, aviation kerosene needs special purification and mixing. Its combustion stability is very high. It burns in the engine of the aircraft, and then ejects rapidly, providing enough power for the aircraft.

  1. 汽油易挥发,而柴油不易挥发。因此,汽油车有燃料蒸发排放,其中碳氢化合物(HC)组成。

  1. Gasoline is volatile, while diesel is not. Therefore, gasoline vehicles have fuel evaporation emissions, which are composed of hydrocarbons (HC).

  2. 汽油容易与空气混合,混合后不易分离。汽油和空气可以混合得非常均匀,几乎没有局部过厚或过薄及液体油滴。汽油分子更小。柴油与空气的混合不均匀。油在高温缺氧下,容易形成碳烟。柴油燃烧时,会产生一些难闻的有机气体。因此,柴油排放有异味。

  2. Gasoline is easy to mix with air, and it is not easy to separate after mixing. Gasoline and air can be mixed very evenly, almost no local too thick or too thin and liquid oil drops. Gasoline molecules are smaller. The mixture of diesel and air is uneven. Under high temperature and hypoxia, oil is easy to form soot. When diesel oil burns, it will produce some unpleasant organic gases. As a result, diesel emissions have a peculiar smell.

  3.化学差异:汽油有更少的碳原子(8-10个),而柴油有12-15个,所以柴油有更多的能量。柴油不需要点火,它会在更高的压力下自动点火,因此效率更高(实际上,利用率只有30%),但它体积庞大且噪音很大。汽油需要点火,所以汽油发动机体积小、噪音小(效率只有15%)。

  3. Chemical difference: gasoline has fewer carbon atoms (8-10), while diesel has 12-15, so diesel has more energy. Diesel does not need to be ignited, it will automatically ignite at higher pressure, so it is more efficient (in fact, the maximum utilization rate is only 30%), but it is bulky and noisy. Gasoline needs to be ignited, so the gasoline engine is small in size and low in noise (efficiency is only 15%).

  味道不同,汽油刺鼻,柴油软弱。不同的颜色,汽油色,柴油色。容量不同,汽油更薄。柴油是厚的。汽车上的点火方式不同,汽油是火花塞点火,柴油是压力燃烧。柴油的抗爆性能较差。与汽油相比,柴油动力更弱,污染更严重,烟雾更重,但价格更便宜。

  Different taste, pungent gasoline, weak diesel. Different colors, gasoline, diesel. Different capacity, thinner gasoline. Diesel is thick. Different ignition methods are used in cars. Gasoline is ignited by spark plug and diesel is combusted by pressure. The antiknock performance of diesel oil is poor. Compared with gasoline, diesel power is weaker, pollution is more serious, smoke is heavier, but the price is cheaper.
