1)‌ Cetane Number: This is an important to measure diesel’s combustion performance. The higher the value, the more full and complete the combustion, the stronger the explosive power of the engine, and the lower the fuel consumption rate. Cetane numbers usually range from 40 to 60

‌2)Sulfur Content: Sulfur content is a measure of the sulfur content in diesel. The national standard stipulates that the sulfur content of diesel cannot exceed 500ppm. If the sulfur content is too high, there are more SO2 and SO3 produced in the process of diesel combustion, these two substances are the main causes of acid rain, causing environmental pollution; In addition, these two substances react with water vapor at high temperatures to form sulfite and sulfuric acid, which seriously corrode the metal components of the engine.

3)density: The density of diesel oil is an important quality indicator, usually expressed in kg/m³. The higher the density, the higher the energy content of diesel oil, the usual index is 0.82~0.855g/ml.

‌4)carbon residue ‌ : Carbon residue refers to the carbonaceous material left after diesel is burned under certain conditions. The lower the amount of carbon residue, the better the combustion performance of diesel, the easier to clean up, and the longer the service life of mechanical equipment

5)Viscosity:Viscosity refers to the internal friction of diesel flowing at a certain temperature. Different models of diesel oil have different viscosity requirements to meet different use environment and equipment needs, diesel viscosity index is generally between 40 and 50, ‌.

‌6)Flash Point:Flash point is an important indicator to measure the flammability of diesel. The higher the flash point, the worse the flammability of diesel, usually above 55 ° C

7)Pour Point:The pour point is an important index to measure the low temperature fluidity of diesel oil. The lower the freezing point, the better the fluidity of diesel at low temperatures. For diesel oil that needs to be used at low temperatures, the freezing point is an important performance index.

8)impurities and moisture:Impurities and moisture in diesel will affect its combustion efficiency and service life. Excessive impurities may lead to oil line blockage; Excessive moisture may emulsify the oil and affect the normal operation of the engine.
