Density of diesel fuel

The main consumers of diesel fuel are trucks, construction and agricultural machinery, as well as rail transport. However, recently, diesel fuel can be found and passenger transport. For all drivers, an exciting issue has always been its price. In automobile engines, diesel fuel is very advantageous and convenient, since it is cheaper than gasoline. The power and economy of engines working on diesel fuel is quite strong, since a high degree of its compression leads to significant savings.

The density indicator is currently the most common, used in the characteristics of all petroleum products. The higher it is, the more energy is generated in the combustion process, and this makes it possible to increase the efficiency of the engine. It affects not only the quality of fuel, but also its use in the winter. Buying diesel fuel, drivers are often not interested in its density, especially in the summer. And while the car is moving normally, they do not think 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 in the winter. When severe frosts occur, the diesel fuel is paraffined and transformed into a gruel-like mass that can clog the entire fuel system. The winter diesel should be equal to 840 kg per cubic meter. If it is summer, having 860 kg per cubic meter, then with a sudden change in temperature the consequences may not be very pleasant. In addition to winter and summer, there is also an Arctic diesel fuel. It has the lowest density, equal to 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 know the density of diesel fuel. To do this, it must be poured into a three-liter jar and put in a room where the temperature does not exceed twenty degrees. In the morning, using a hydrometer, measure the density. However, it should be taken into account that in this way one can know only what it is - summer or winter, but the qualitative indicator can not be determined in this way.

In the event that the street frost to minus ten degrees, you can directly at the gas station to analyze what the density of diesel fuel. To do this, in a small amount, you need to pour it on the metal and observe whether its structure will change. If it flows normally, there will be no doubt that it is winter. In case it becomes cloudy and will slightly harden, this means that the diesel fuel is summer, and if the frost is cold it freezes completely. To do this, just look at the refueling gun and see for yourself.

Therefore, if the driver is absolutely certain that the diesel fuel was produced in the factory, he, based on knowledge of its density, can determine its own membership, as well as the freezing temperature. Well, if it is low-grade, then there will be no sense in its visual analysis.

Winter diesel fuel of high quality becomes turbid at forty-five degrees, and freezes at forty-eight. If we talk about the Arctic, the temperature of its congealing is generally sixty-five degrees.

Completely to be assured of quality of fuel it is possible only after laboratory checks with use of fractional distillation. There are other methods of determining quality, more modern.

Each driver should know that it is best to refuel the car at those refuellings that have been checked repeatedly. And although the density of diesel fuel plays an important role, however, there are many other of its indicators that affect the operation of the engine.
