What is the CAS number of diesel?

[BenjaminFitz]

The CAS number of diesel is 68334-30-5. Below is an introduction to diesel: 1. Overview: Diesel is divided into two main categories: light diesel (boiling point range approximately 180-370°C) and heavy diesel (boiling point range approximately 350-410°C). The most important performance characteristics of diesel are ignition quality and fluidity, with the technical indicators being cetane number and pour point, respectively. Current specifications in China require the sulfur content in diesel to be controlled between 0.5% and 1.5%. 2. Grades: Similar to gasoline for vehicles, diesel also has different grades. Diesel is graded by pour point, with light diesel having six grades: 5, 0, -10, -20, -35, and -50, and heavy diesel having three grades: 10, 20, and 30. The selection of diesel is based on the operating temperature. Diesel vehicles primarily use the latter five grades of diesel. When the temperature is above 4°C, 0# diesel is selected; when the temperature is between 4°C and -5°C, -10# diesel is selected. When the temperature is between -5°C and -14°C, -20# diesel is selected; when the temperature is between -14°C and -29°C, -35# diesel is selected. If the selected diesel grade is higher than the aforementioned temperatures, the fuel system in the engine may experience wax formation, blocking the fuel lines and affecting the normal operation of the engine.

Diesel is not a single substance but a mixture, primarily composed of various hydrocarbons, so it doesn't have a unique CAS number. However, the standard CAS number for common diesel fuel is 68334-30-5, which serves as a universal identifier in chemical databases. Every time I help someone with diesel-related issues, I always remind them: it's not a pure chemical, and the CAS number is mainly used for safety data sheets, such as when cleaning up oil stains or handling spill incidents, to quickly check the composition and treatment methods. In automotive applications, using the wrong fuel in a diesel engine can cause severe damage, so knowing this number can help you verify the authenticity of the fuel at gas stations. For daily driving, there's no need to overthink the details, but having some emergency knowledge is always good.

Speaking of diesel, I've noticed during vehicle use that it's quite complex in composition, not purely a single substance, so the CAS number is typically represented as 68334-30-5. I often drive diesel vehicles on long trips and have seen the CAS number on fuel drum labels, but what I care more about in actual driving is how fuel quality affects the engine. For example, using inferior diesel or blended fuel can easily cause engine shaking or black smoke emissions. The CAS number serves for chemical identification and isn't particularly meaningful to car owners unless you're dealing with spill incidents requiring safety reports. For maintaining your beloved vehicle, regularly checking the fuel lines and filters is far more important—don't let impurities clog the injectors. These small maintenance habits add up to keep your car running smoother.

As someone who frequently works with diesel engines, I can tell you that diesel is a mixture, commonly identified by the CAS number 68334-30-5. When repairing vehicles, this number is crucial, especially when dealing with oil contamination or replacing fuel system components, as it helps in checking safety regulations. I always emphasize: don't just focus on the number; diesel quality affects engine lifespan. Poor-quality fuel can lead to carbon buildup and reduced power, even posing a fire risk. From a maintenance perspective, inspecting the fuel pump and injectors is more practical than memorizing numbers, saving money and ensuring peace of mind.

From the perspective of learning automotive knowledge, diesel is a fuel mixture with a standard CAS number of 68334-30-5. I found that this number acts like an ID card, uniquely identifying it, but there are significant variations in practical usage. Diesel has wide applications in vehicles, and engine cold-start performance depends on fuel purity. Relatedly, CAS numbers are used in emergency incidents to identify leaked substances, helping firefighters respond quickly. Understanding these can make driving safer, but ordinary people don't need to memorize them rigidly—paying more attention to daily fuel sources is sufficient.
