The difference between No. 93 gasoline and No. 92 gasoline 1. The larger the gasoline label in terms of composition, the higher the proportion of isooctane 2. In terms of characteristics, the higher the gasoline model, the higher the ignition point. No. 3.93 gasoline releases more heat than No. 92 gasoline
The composition of gasoline is mainly composed of hydrocarbons such as aliphatic hydrocarbons, naphthenic hydrocarbons and a small amount of oxides. Gasoline is labeled according to the level of octane, and the higher the gasoline model, the higher the proportion of isooctane. For example, the proportion of isooctane in No. 93 gasoline is higher than that of No. 92 gasoline, which is their difference. Because of its different proportions, the ignition point of No. 93 gasoline is higher than that of No. 92 gasoline. Therefore, No. 93 gasoline is suitable for vehicles with a large engine compression ratio. At the same time, in the same case. No. 93 gasoline will generate more heat due to its high ignition point, so it will feel that the car is more powerful in using No. 93 gasoline than No. 92 gasoline.
But many riders will have a misunderstanding, is not the higher the oil label, the quality of gasoline is better, is not to refuel to add high gasoline, in fact, it is not so. The model selection of gasoline is mainly based on the compression ratio of the engine. The larger the compression ratio, the higher the fuel label should be selected. This is because the compression ratio is large, and if you choose a low model of gasoline, it is prone to knocking. So if the car recommends adding No. 98 gasoline, but we add No. 92 gasoline, it is easy to cause damage to the engine.
Therefore, the choice of gasoline should be based on the actual situation of the car, not the higher the better, nor to save money, plus gasoline below the requirements. This is more damaging to the vehicle, today's sharing is here, if you like please like, favorite, forward thank you.
