Winter operation of transport with diesel engines for many of their owners is becoming a real test. The problem is based on the technical features of the diesel engine, but on the fact that diesel fuel has a bad property to freeze. In other words, as a result of crystallization of paraffins, which are contained in the fuel, it is done with muddy, and with a decrease in the temperature on the street, it is made similar to Kissel. It is worth noting that precisely the crystals of paraffins, creating lumps, settle in the fuel pump, clog the pores in the fuel filter, prevent the flow of fuel to the cylinders, which paralyzes the operation of the motor. Even a fully serviceable power unit, which is covered with high-quality motor oil with a small low-temperature viscosity coefficient, high-quality candles of heating, a new starter and battery are not able to guarantee a confident launch of the motor, if there is no seasonal diesel fuel in the automotive tank.

Diesel fuel in winter than summer diesel fuel is different from winter

To date, three brands of automotive diesel fuel can be distinguished - winter, summer and arctic. Despite the significant difference in the operational parameters, they do not differ from each other or the smell or color. The main difference between them is the content of paraffin, which affects the turbidity temperature and the loss of the required properties.

To obtain the winter and arctic fuel, the fuel is subjected to dewaxing. This production process increases the cost of diesel fuel, so there is a risk to face unscrupulous car refills, which even with the arrival of winter sell summer diesel fuel, very often, issuing it for the winter to save it. And suffer, as a result, the owners of diesel cars.

Diesel fuel GOST, which is regulated by GOST, at what temperatures is used

According to GOST 305-82, diesel fuel must withstand such temperature values:

1. Summer fuel should be adapted for driving at temperatures to zero degrees Celsius and above.
2. Winter fuel is recommended for operation at temperatures up to -30 degrees Celsius.
3. Arctic - up to -50 degrees Celsius.

Diesel Fuel Closure Temperature

The turbidity process (that is, crystallization) of diesel summer fuel occurs at a temperature of -4 degree with the release of peculiar embryos of crystals separated from each other for a significant distance. If the temperature decreases to -7 degrees Celsius, the intensive growth of these crystals occurs, the formation of new and appearance of lumps. As soon as these lumps reach the size of the microporet filter, the fuel purification filter is clogged, thereby blocking the flow of fuel to the motor. The temperature in which fuel thickened to that measure, which is no longer capable of passing through the fuel filter and the fence mesh is called PTF (that is, the limiting filtration temperature). For winter fuel, PTF should be at least -25 degrees Celsius.

At temperature -35 degrees Celsius for winter fuel and -10 degrees Celsius - for summer, paraffin crystal seals occurs and frozen fuel, which turns into an unsuitable stupid substance. If summer diesel fuel at a low-grade quality refueling, it begins at a temperature of +5 degrees Celsius. Therefore, even insignificant, it would seem, changing transparency or the color of diesel fuel is a reason for concern. Lounge is the first stage of the fluidity of the fuel when paraffin crystals are hardly passing through the fuel filter and clog it, worsening the fuel passability.

The best antigel for diesel fuel, which gives an antigel powder, how additives work

The depressor additive "Antigel" is a complex compositional composition, the work of which is aimed at reducing the temperature of the freezing of the diesel fuel and limiting filtering temperature. It is worth noting that antigels do not affect the cloud temperature. Lounge is a normal fuel reaction to the ambient temperature.

Any antihel is effective only when it is covered in fuel before it thickens, since it is not possible to dissolve paraffin lumps (agglomerates) for no one antigel. Special additives are successfully coped with this task - diesel fuel defrosts.

How does the antigel act? The elements of the antigel interact at the molecular level with paraffin crystals and do not give crystals the ability to score the fuel filter. That is, the depressor molecules at negative temperatures are settled on crystals, impede their growth, and also do not give them the opportunity to grow into the agglomerates that clog the fuel filter. Thus, paraffin crystals are freely passing through the pores of the fuel filter. Astrohim is one of the best antigels.

Detergent of diesel fuel, principle of operation and how to apply it

If the wasolar in the fuel system and the tank thickened, it should be used by a special diesel fuel defrost. In case of freezing, the fuel with an effort is hampered by the system. Fuel tubes and filter elements refuse to skip the composition. It violates the correct operation of the engine and may entail a serious breakdown or the impossibility of running.

The only output is the use of a defrost, whose task is to dissolve ice and the melting of paraffin crystals. After a certain time, fuel becomes liquid, and the car manage to start.

One of the most common and quality products in our time is the Hi-Gear HG4114 defrost. Its main purpose is to reduce the freezing temperature and the rapid dissolution of the paraffins of thickened diesel fuel. In addition, the composition also easily copes with ice crystals, which accumulate in the fuel system and counteract its correct operation.

What is the feature of the product? As is known, the hydrocarbons of paraffin type are contained in the diesel engine, which are converted to crystals in the case of cooling. The action of the defrostant is directed to them, as a result of which the crystals are gradually dissolved. As a result, low-temperature composition qualities are improved, the risk of combustible mixture is reduced.

To ensure the effectiveness of the composition, it is important to use it correctly:

1. Return and disassemble both filtering elements (coarse and fine cleaning). At the same time, it is necessary to remove all the crystallized fuel from them.
2. We pour Hi-Gear HG4114 into a filter, pre-mixing it with diesel flammable in a 1 to 1 ratio.
3. We put the filter element in place.
4. Fill into the tank the defrostor at the rate of one to two hundred. Then you need to wait 20 minutes so that diesel fuel is completely dissipated. Next, run the motor.
   
5. To reduce the risk of fuel freezing to a minimum, it is desirable to use this tool at each refueling.

Water in the fuel system - a serious threat, how to deal with it

From water that comes with fuel, the fuel system suffers primarily. Signs of water in the tank can distinguish any, even a novice motorist. If your vehicle does not develop the required power, the engine works with interruptions, and recently you refuel, it is most likely water got into the tank. In addition, if in the winter time the car does not start, and the tank is refilled, it means it is quite possible that the remnants of water frozen in the fuel lines and now they should be shred.

There are a lot of ways to quickly remove water from the fuel system. The first method is the most applied due to its availability and simplicity - removal of water with alcohol. You can actually apply any alcohol - ethyl, isopropyl, and so on. For cleaning it is necessary to pour into the tank 200-500 grams of alcohol. As for diesel engines, instead of alcohol, it is desirable to apply 200 grams. Machine oil for fifty liters of diesel.

In addition to alcohol there are special means for removing water from the fuel system - dehydrators. In our country, such products are represented by brands such as STP, Castrol, ELF and other leading auto chemical manufacturers. The advantage of using these chemical additives is a wide range of action. In addition to removing water, they prevent the occurrence of corrosion on the metal surfaces of the pump, fuel tubes, tank and so on due to the anti-corrosion additives contained in them.

Diesel fuel Euro

The system of environmental standards euro has previously been distributed only to the territory of the European Union. Today, this system has also been introduced in Russia. The euro strategy is aimed at reducing the content of harmful and unwanted substances in the exhaust. It means damp gas, sulfur compounds, polyaromatic hydrocarbons (for example, benzene). The table presents the requirements for different types of diesel fuel:

Best diesel fuel, rating of 10 diesel fuel stations
