The main consumers of diesel fuel are trucks, construction and agricultural machinery, as well as rail transport. Recently, however, passenger vehicles can also be found with diesel fuel. For all drivers, the price was always an exciting issue. It is very convenient and convenient to use diesel fuel in automobile engines, since it is cheaper than gasoline. The power and efficiency of diesel engines is quite strong, since a high degree of compression leads to significant savings.
The density index is currently the most common used in the characteristics of all petroleum products. The higher it is, the more energy is generated during the combustion process, and this allows you to increase the efficiency of the engine. It affects not only the quality of the fuel, but also its use in the winter. When buying diesel fuel at gas stations, drivers are often not interested in its density, especially in the summer. And while the car is moving normally, they are not thinking about anything.
But the density of diesel fuel plays a big role in the fate of the car, and, as a rule, it is always remembered about it in winter. When severe frosts occur, diesel fuel waxes and turns into a mushy mass that can clog the entire fuel system. Winter diesel fuel should be equal to 840 kg per cubic meter. If it is summer, having 860 kg per cubic meter, then with a sharp change in temperature, the consequences may not be very pleasant. In addition to winter and summer, there is also Arctic diesel fuel. It has the lowest density of 830 kg per cubic meter and can easily withstand frost.
Of course, it is visually difficult to determine which fuel is poured into the tank. It remains only to believe the documents on it. But at home, you can find out the density of diesel fuel. To do this, you need to pour it into a three-liter jar and put it in a room where the temperature does not exceed twenty degrees. In the morning, use a hydrometer to measure the density. However, it should be noted that in this way you can only find out what it is - summer or winter, but a qualitative indicator cannot be determined in this way.
If the street is freezing to minus ten degrees, you can directly analyze the density of diesel fuel at a gas station. To do this, a small amount of it needs to be poured onto the metal and observe whether its structure will change. If it flows normally, then there will be no doubt that it is winter. If it becomes cloudy and slightly hardens, this means that diesel fuel is summer, and in severe frost it freezes completely. To do this, just look at the refueling gun and see for yourself.
Therefore, if the driver knows for sure that diesel fuel was produced under factory conditions, he, based on knowledge of its density, can determine its affiliation, as well as the freezing temperature. Well, if it is low-grade, then there will be no sense in its visual analysis.
High-quality winter diesel fuel becomes cloudy at forty-five degrees, and freezes at forty-eight. If we talk about the Arctic, then the temperature of its solidification is generally equal to sixty-five degrees.
You can be completely sure of the quality of fuel only after laboratory tests using fractional distillation. There are other methods of determining quality, more modern.
Every driver should know that it is best to refuel a car at those gas stations that have been checked repeatedly. And although the density of diesel fuel plays an important role, however, there are many other indicators that affect the operation of the engine.
