Is Diesel with a Flash Point Below 60 Considered a Non-Compliant Product?
2 Answers
Diesel's flash point refers to the combustion limit of diesel, which is the temperature at which it starts to ignite when exposed to a flame under specified conditions. Here is some relevant information: 1. Diesel: The most important use of diesel is for diesel engines in vehicles and ships. Compared to gasoline, diesel has a higher energy density and lower fuel consumption rate. Due to its low energy consumption, some small cars and even high-performance vehicles have switched to diesel. 2. Flash Point Level: The flash point of diesel is mainly related to its volatility. The lighter the fraction, the easier it is to evaporate, and the lower the flash point. The lower the flash point of diesel, the more easily it can be ignited by a flame, increasing the risk of fire.
I've been driving diesel vehicles for over a decade and always pay close attention to the flash point issue. The flash point is the temperature at which diesel begins to vaporize. If it's below 60°C, the fuel vaporizes too quickly and can easily ignite upon contact with fire, which is extremely dangerous. According to national standards, such as China VI regulations, the flash point must not be lower than 60°C, otherwise it's considered substandard. I once used low flash point fuel and noticed a strong fuel odor after refueling. It nearly caused a small fire when parked, and I later found out its flash point was only 55°C. Using such fuel not only poses significant safety risks but may also clog fuel injectors over time and increase engine load. I recommend everyone stay vigilant when refueling—choose reputable gas stations and avoid cheap, inferior products. Safety should always come first.
