Basic Characteristics of Diesel
Diesel is a mixture of hydrocarbons (with carbon atoms numbering approximately 10 to 22). Compared to gasoline, diesel has the characteristics of being less volatile and having a higher ignition point. These properties make diesel less prone to quickly ignite under normal circumstances compared to gasoline. The primary purpose of diesel is to fuel diesel engines, which typically utilize compression ignition, where air containing diesel vapor is compressed to raise its temperature to the diesel’s combustion point, thereby enabling combustion to generate power.
Ignition Conditions of Diesel
Although diesel itself is not highly volatile, it can still ignite under specific conditions. For instance, when diesel vapor encounters an open flame at 60 degrees Celsius, combustion or even explosion can occur. Therefore, precautions against fire and explosion are necessary when storing and using diesel.
Safe Use of Diesel
To ensure safety, certain operational procedures should be followed when using diesel, such as prohibiting open flames and cell phones at refueling stations to prevent static electricity-induced fires. Additionally, diesel should be allowed to settle and be filtered adequately before use to remove impurities, typically for no less than 48 hours. Inside the vehicle cabin, attention should be paid to odors, and any signs of oil leaks on the ground should be observed after parking. Any anomalies should be promptly checked at a repair station.
Autoignition Point of Diesel
The autoignition point of diesel refers to the lowest temperature at which diesel will spontaneously ignite under specified conditions without a flame. According to data, the autoignition point of diesel is 220°C, meaning that diesel needs to be at a temperature of at least 220°C to begin combustion under normal atmospheric pressure.
Conclusion
In conclusion, diesel is not a highly flammable fuel, but its potential hazards should not be overlooked. Proper storage and usage methods are crucial for preventing fires and safeguarding personal safety.
