Why does the Tayron require 98-octane gasoline?

[StPaisley]

Due to the addition of the Tayron's particulate filter, using lower-octane gasoline can easily cause blockages, leading to a significant increase in fuel consumption. Relevant details are as follows: 1. Gasoline octane rating: The octane rating of gasoline represents its resistance to knocking. For example, 95-octane gasoline consists of approximately 95% isooctane and 5% heptane. Since isooctane has better anti-knock properties compared to heptane, a higher octane rating indicates better anti-knock performance. By extension, 98-octane gasoline means even better anti-knock performance. 2. 98-octane gasoline: 98-octane gasoline is gasoline whose knocking resistance is equivalent to a mixture of 98% isooctane and 2% heptane. Engines with high compression ratios should use high-octane gasoline. Using low-octane gasoline in a high-compression engine can cause abnormal combustion, resulting in knocking, increased fuel consumption, and reduced driving power. Compared to other octane ratings, 98-octane gasoline offers stronger anti-knock properties and higher combustion efficiency, providing more powerful performance. However, due to its higher rating and price, it is often used by luxury cars and is referred to as "premium gasoline."
