1. Add standard diesel.
For the sake of convenience or saving money, many people will choose to buy diesel fuel by themselves, but the wax content of non-standard diesel is uncertain, and the wax is more likely to form in winter, so we recommend using standard diesel.
2. Use anticoagulants correctly.
When refueling, in addition to choosing the right diesel according to the temperature, the card brothers can also use anti-coagulation additives to reduce the cold filter point and freezing point of the diesel when the diesel wax is formed, improve the low-temperature fluidity of the diesel, and avoid wax formation. However, it should be noted that regular diesel special anticoagulant additives must be used.

Summary. As we all know, there are seven different grades of diesel in the Chinese domestic market. The lower the diesel grade, the more frost-resistant it is.
But, I'm sure you don't know the freezing temperature of diesel. How many degrees Celsius wax does No. 0 diesel wax at minus? Let's take a look at diesel.
How many degrees of sub-zero diesel waxing? Scientifically speaking, the freezing point of diesel No. 0 is zero degrees Celsius. When the temperature drops below freezing, the diesel fuel starts to wax.
But generally speaking, 0 diesel is suitable for use at temperatures between 8 4, and when the temperature is lower than 4, the fluidity of 0 diesel will deteriorate significantly. When we refuel, we should choose according to the actual local temperature, otherwise the diesel car is easy to ignite due to diesel solidification and ignition failure.

What should I do if my diesel car has been waxed? The best thing to do is to pour the right amount of kerosene into the fuel tank to improve the freeze resistance of the diesel after it has completely solidified. In general, the ratio of diesel fuel to kerosene is 50:
1, that is, 50 liters of diesel fuel need to be mixed with 1 liter of kerosene. It should be noted that when blending kerosene, it is important to ensure that there is no water in the container, otherwise the engine may be damaged.
Can diesel be mixed with gasoline? Diesel cannot be mixed with gasoline. Diesel engines use a mixture of gasoline and diesel fuel, which can cause engine knocking and damage to engine parts.
Because diesel and gasoline have different ignition points, diesel and gasoline engines work differently, so do not use a mixture of diesel and gasoline in a diesel engine.

Anticoagulant additives are added.
In winter, due to the sudden drop in temperature and the low speed of the crankshaft, the viscosity of the engine oil increases greatly at low temperatures, and it is easy to solidify, and the minimum speed required for engine start cannot be reached. If the diesel fuel is waxed, anti-coagulant additives should be added. The use of anticoagulant additives can be emergency, to avoid wax, convenient and economical, the diesel anticoagulant additives are added to the diesel fuel in a certain proportion, it can be effective anti-condensation and anti-freezing, but it is worth reminding that you must buy regular anti-coagulation additives.

In the case that the wax is not serious, use hot water to pour the oil circuit, filter element, oil pump, etc. several times, pump the oil exhaust, start the cycle for a period of time, and the wax will melt. If the wax hanging is serious, replace the high diesel oil, remove the non-thermal conductive pipeline in the oil inlet pipe, pour it with hot water several times, and then pump the oil exhaust to start.
The high melting point contained in diesel fuel is that paraffin hydrocarbons are precipitated in flake or needle-like crystals, and these crystals slowly increase and are connected to each other through their water chestnuts to form a triangular network structure, which adsorbs and wraps the oil with low melting point, so that the oil loses fluidity, and the oil will solidify only when the paraffin wax is precipitated in the diesel. In addition to the temperature, it is also possible that the right diesel fuel was not selected.

Hello dear <>, happy to answer for you. How to solve the problem after the diesel car waxes in winter. Diesel wax is caused by the ambient temperature in the use area is lower than the diesel mark.
Therefore, the following measures can be taken when the diesel pickup truck is waxed in winter: First, replace the diesel fuel and replace the diesel that can meet the bottom temperature requirements of the environment in the use area, such as -35 diesel when the ambient temperature is lower than -25. The second is to use hot gas to heat the fuel tank or use warm supplies to heat the fuel tank and oil circuit system before and during use.
Therefore, in winter, diesel pickup trucks can be done like this: one is to change the oil, and the other is to keep warm. <>

Depending on the season, the maintenance is different. Before starting the heavy truck diesel engine, it is necessary to add enough coolant to avoid lack of water to start. Do not add cold water when the body temperature is too high to avoid the cylinder cracking.
In winter, pay attention to the discharge of water (or add antifreeze) when parking at low temperature outdoors to prevent the cylinder from freezing and cracking; The vehicle must be operated at the specified temperature, and cooling water is indispensable to avoid overcooling or overheating of the engine; Before starting, the oil level should be checked, and the oil volume must reach the scale specified on the oil dipstick, and it should be added or replaced if necessary; Engine maintenance should strictly follow the operating procedures to avoid undue man-made damage.
In winter, you need to buy diesel with low condensation point to use, diesel is graded according to the condensation point, light diesel oil has six grades, -10, -20, -35, -50, and heavy diesel oil has three grades.
Diesel fuel is selected based on the temperature at which it is used. Diesel vehicles mainly use the last 5 grades of diesel, and 0 diesel is selected when the temperature is above 4; When the temperature is 4--5, -10 diesel is selected; When the temperature is -5 --14, -20 diesel is selected; When the temperature is -14 --29, -35 diesel is selected; If the grade of diesel is higher than the above temperature, the fuel system in the engine may form wax, block the oil circuit, and affect the normal operation of the engine.

Diesel fuel at minus 5 degrees cannot be hung with wax and is easy to clog.
If the grade of diesel is higher than the temperature not reached, the fuel system in the engine may become waxed, clogging the oil circuit and affecting the normal operation of the engine.
Diesel solidification and wax hanging is a crystallization phenomenon that occurs when the temperature is reduced.
Diesel fuel contains a certain amount of wax (i.e., n-alkanes), and when the temperature decreases, these waxes will gradually precipitate and form wax crystals, which will solidify the diesel, that is, wax. Diesel fuel is graded according to the condensation point, and there are six grades of light diesel oil 50, -10, -20, -35, and -50, and there are three grades of heavy diesel oil.
Diesel fuel is selected based on the temperature at which it is used. Diesel vehicles mainly use the last 5 grades of diesel.
When the temperature is above 4, 0 diesel is used, -10 diesel is selected when the temperature is 4--5, -20 diesel is selected when the temperature is -5--14, and -35 diesel is selected when the temperature is -14--29.
Traditionally, due to the different structures of gasoline engines and diesel engines, gasoline engines often belong to high-speed engines, which are faster in the long run, while diesel engines are low-rpm and high-torque engines, which are generally used for trucks, etc., but now each engine has developed greatly, so their respective advantages and disadvantages are not very obvious.

Gasoline cars are ignited by spark plugs, diesel cars are compression-ignited, gasoline cars are fast-accelerating, diesel cars are powered, in contrast, diesel cars are more fuel-efficient.
The fuel injector is easy to clog the oil pump and loves bad ......These problems about diesel vehicles were two years ago, that is, the quality of diesel in our country did not meet international standards, but this is no longer the case in the past two years. China's diesel has made great progress, now there is not only diesel Jetta, but also diesel Bora, diesel Audi seems to have it, it is sold on the market, the quality of Jetta's car is no problem, the leather is durable, the diesel car is fuel-efficient, the power is good, winter, have you ever seen a car to rescue the problem in winter? I didn't have it anyway. >>>More
