What is Gasoline Anti-Knock Property?

07/29/25 5:34pm

Gasoline anti-knock property refers to the ability of gasoline to resist knocking when burning in an engine, which is a key indicator of gasoline's combustion performance. Knocking is caused by abnormal combustion of gasoline in the engine. The octane number of gasoline is a commonly monitored indicator. Based on anti-knock properties, gasoline products are classified into 92, 95, and 98 grades, with different grades exhibiting varying operational performance. Strong anti-knock properties allow for the use of higher compression ratio engines, which can enhance engine power, reduce fuel consumption, and improve engine efficiency. Gasoline is produced by refining various gasoline components such as straight-run gasoline, catalytic cracking gasoline, and catalytic reforming gasoline, then blending them with high-octane components. It is primarily used as fuel for spark-ignition internal combustion engines in automobiles.

How to Pass Through Waterlogged Sections?

When driving slowly through waterlogged sections, avoid artificially raising the water level, as speeding up can increase the water level. Once the water exceeds the engine's air intake, it can be sucked into the engine, causing it to stall. Relevant details are as follows: 1. Low Speed: When passing through waterlogged sections, as long as the water does not cover more than two-thirds of the tires, the speed does not exceed 5 km/h, and you drive steadily in the lowest gear, you can safely navigate through the water. 2. Steady Driving: Low speed allows the driver to react promptly in case of danger. It also prevents splashing large waves, avoiding water intake into the air intake or exhaust pipe. Additionally, it's evident that a vehicle moving at low speed is less likely to stall, ensuring a smoother and safer passage.
