What is the ignition point of gasoline?
2 Answers
The ignition point of gasoline is 415-530 degrees Celsius. Introduction to gasoline octane ratings: It represents the ratio of the actual anti-knock performance of gasoline to that of standard gasoline. The higher the octane rating, the stronger the anti-knock performance. Composition of gasoline: Standard gasoline consists of isooctane and n-heptane. Isooctane has good anti-knock properties, and its octane number is defined as 100; n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with its octane number defined as 0. Selection criteria for octane ratings: The primary criterion for selecting gasoline octane ratings is the engine's compression ratio, which is also a core energy-saving indicator of modern cars.
The ignition point of gasoline, which is the temperature at which it self-ignites, generally ranges between 250 to 300 degrees Celsius, more specifically around 257 to 280 degrees. I often encounter this issue when repairing cars because engine temperatures run high during operation. If gasoline leaks onto hot components, it can easily cause a fire. I remember one summer when I was helping a friend inspect their car and noticed gasoline stains near the exhaust pipe. Fortunately, we addressed it in time, or the consequences could have been dire. That's why I always recommend storing gasoline in metal containers placed in cool, shaded areas—never in the trunk. While cars are designed with cooling systems, extra caution is still necessary during repairs to avoid sparks from tool friction. Understanding this ignition point helps us prevent accidents, and safe driving should always be the top priority.
