. For car owners, fuel economy is a permanent topic. Generally speaking, the owners of the car often judge whether the operation of the gas station is good or bad according to whether the oil is fuel-efficient or not, and directly affect the consumption habits. Many operators of gas stations also believe that the greater the oil density, the more fuel-efficient, and according to this, the oil products they manage will be guided and promoted to customers. However, according to the industry experts of Sinochem Total, according to scientific analysis, the oil density does not determine whether the oil is fuel-efficient or not. Sinochem Total is revealed to you: Why do you say this? Sinochem Total’s industry experts conducted in-depth analysis from four aspects. First, density is a property of matter, with different gasoline densities. Physically, density is defined as the ratio of mass to volume. The density of different substances is different, and the density of the same substance is the same. Gasoline is a mixture of substances, and the density of different gasolines is different. For example, the density of 92# and 95# gasoline is between 0.72-0.75, and the density of diesel is between 0.81-0.85. Density as a physical property, the greater the density, the greater the quality of the same volume of oil. Second, there are many different ways to measure oil density. On the one hand, the density of the same kind of gasoline is different, the density of gasoline and diesel is quite different. The distinction between 92# gasoline, 95# gasoline and diesel can avoid the unloading of oil. On the other hand, the liquid level meter reading * density = weight, for the no-floor scale, only the gas station of the liquid level meter, the density can be used for oil metering, converted into tons, to determine that the oil is not heavy enough. On the other hand, if the density measured by the densitometer is significantly increased or decreased than the density of the outlet, indicating that the quality of the oil changes, the unloading should be suspended. Therefore, the density can determine whether the quality of the oil during transportation changes. Again, there is a range of oil density, not the bigger the better. Scientific analysis shows that among the 50-liter fuel tanks, the oil with a density of 0.75 is 1.5 kg larger than the oil with a density of 0.72, which is equivalent to the mass of two 2.0 liters of oil. For high-density oils, the reconstituted content is larger than that of low-density oils, such as alkane heavy aromatics. These recombinations are often not completely burned and discharged into the air, causing air pollution and increasing fuel consumption. Therefore, this large 1.5 kg quality oil can hardly save 2.0 liters of oil. Finally, density is not the root cause of fuel consumption. The root causes of fuel consumption are gasoline calorific value, gasoline combustion efficiency and engine thermal efficiency. At the same time, the comprehensive factors such as driving conditions, car conditions and driving habits will also affect fuel consumption. In summary, density is a physical property of different oil products. The density of oil measurement at gas stations is various, and the range of oil density is limited. Fuel consumption is affected by various factors. “Therefore, just by the density, it is not possible to judge whether it is fuel-efficient or not. ” Sinochem Total’s industry experts said.
