What is the ignition point of gasoline?
2 Answers
The ignition point of gasoline is 427°C. Below is relevant information about automotive gasoline: Overview: Automotive gasoline is a liquid fuel refined from petroleum, primarily used for cars and motorcycles. Classification: In China, automotive gasoline is divided into unleaded and leaded categories. Unleaded gasoline comes in three octane ratings: 90, 93, and 95 RON (Research Octane Number). Leaded gasoline has three octane ratings: 90, 93, and 97 RON. Among them, the lead content in 90 RON does not exceed 0.35g/L, while the lead content in 93 and 97 RON does not exceed 0.45g/L.
The ignition temperature of gasoline, which we commonly refer to as the flash point, is actually around 280 degrees Celsius. I remember that when working inside a car engine, the temperature can get very high. If oil residue accumulates too thickly, it can easily reach this point and ignite. That's why it's important to regularly clean off oil residue. Gasoline isn't as prone to spontaneous combustion as one might think, but once the temperature gets extremely high, especially in poorly ventilated areas like storing gasoline cans in a garage, extra caution is needed. It's recommended to store gasoline away from direct sunlight and heat sources—places like near the exhaust pipe are absolutely off-limits. If you notice an unusually strong smell of gasoline, never check it with an open flame; ventilate the area immediately. I always believe that safety comes first, especially in car maintenance. Paying attention to these small details can prevent major issues.
