Hollywood efficient use of diesel PPD can protect the vehicle safe driving in winter onset of winter, rain, snow and other inclement weather occurs frequently winds, temperatures plunged Supplying depressant, cold weather, often resulting in unused low-grade diesel vehicles frequently stalled, suspended some way causing road congestion, vehicles, passengers stranded, seriously affecting people's normal life, but also to the owners brought great economic losses. Diesel oil problems caused due to winter seasonal problem is not working properly, once again placed in front of people, relevant examples abound. Last November, the Shijiazhuang-Taiyuan high speed diesel cars stalled due to a sudden temperature drop depressant Jiangsu Province, traffic jam night for two days; January of this year, Henan temperatures plunged large passenger vehicles on the road, "lying nest" depressant, some owners actually lead to more than baking tank explosion; April this year when temperatures plunged, once led relief supplies destined for Yushu ..... depressant join, you can change the size of the crystalline form of wax or wax crystals, but 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 Shanghai depressant 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.
