What is the difference between diesel No. 92 and No. 95?

[Sullivan]

The differences between diesel No. 95 and No. 92 are as follows: 1. Different main components: Analyzing the main components of No. 95 gasoline and No. 92 gasoline, No. 92 gasoline is composed of 92% isooctane and 8% n-heptane, while No. 95 gasoline consists of 95% isooctane and 5% n-heptane. The reason why No. 95 gasoline is slightly more expensive is due to the higher proportion of isooctane. 2. Different functions: Isooctane also has another function, which is anti-knock. In other words, the higher the proportion of isooctane, the better the anti-knock performance. Each engine will be given a comprehensive evaluation before leaving the factory, and based on the engine's performance and other data characteristics, the anti-knock requirements will be proposed, that is, what grade of gasoline should be used.
