Diesel at work, diesel by coarse and fine filter, then through the high-pressure pump, fuel injectors is injected into the cylinder. When the temperature drops diesel cold filter plugging point temperature Supplying diesel PPD, wax crystals formed will affect the normal oil filter clog the oil, thereby affecting the normal operation of the engine. After adding diesel depressant, when the temperature is lowered, when just a wax crystal formation depressant will play the role of a nucleating agent together with wax crystals precipitated or adsorbed on the surface of the wax crystals, preventing wax intergranular bonded to each other, preventing the formation of continuous crystalline network to make more subtle wax crystal particles lowest wholesale diesel PPD, can well pass filter. Depressant such damage or alter the function of the crystalline wax Hollywood diesel PPD, you can reduce the pour point and cold filter plugging point of diesel. Depressant adding diesel PPD, you can change the size of the crystalline form of wax or wax crystals, but it does not prevent the precipitation of wax crystals and reduce the amount of wax precipitation. Therefore, the role of depressant, when the temperature drops near the diesel cold filter plugging point that diesel will be a large number of fine particles of wax crystals, so that the oil becomes cloudy appearance, but this does not affect diesel smoothly through filter (or filters). According to the pour point of light diesel oil into different grades, each grade has a corresponding pour point and cold filter plugging point index. 0 refers to the grade of light diesel oil for diesel pour point of not higher than 0 ℃, the corresponding index for cold filter plugging point of no higher than + 4 ℃. So people often think, No. 0 diesel oil to show that it can be used normally at 0 ℃, which is actually a misunderstanding. Precisely, the pour point of No. 0 diesel 0 ℃ only in higher than the temperature of the cold filter plugging point + 4 ℃ in order to work properly, and in the cold filter plugging point and below the temperature of the diesel has been unable to pass filter net (or filters); when the temperature dropped to 0 ℃, the oil will lose mobility and showed coagulation status.
