The 315 CCTV evening party exposed gasoline fraud. Not only did people not drink milk this year, but they also failed to get qualified oil. Although the 315 exposure of fake gasoline, diesel fraud is also the hardest hit. Have you ever heard of "tire oil", "black diesel oil" and "blending oil"? The small editor will take you to pick up the fake diesel on the market.
1. waste tire oil refining
Some black oil refineries will buy cheap tyres from the repair shop and use "tires" to make "Diesel". After putting the waste tires into the boiler, after 8-10 hours of atmospheric pressure, the steel wire and impurities in the tire will precipitate to the bottom of the furnace, and the lighter oil will float on it. Through the pipeline, the oil will flow out of the outlet and become a "Diesel" after the oil tank is cooled. This oil is not refined and refined, and has many impurities, but it can burn. Finally, adding the decolorant, the black tire oil turned into a good color diesel oil, which can not be seen by eyes alone.
2. waste oil refining
This diesel oil refinery requires three programs. First, the waste oil is heated at a high temperature. When it is heated to 360 to 400 degrees centigrade, the components of the oil in the waste oil are evaporated into oil and gas. The evaporated oil and gas are entered into the cooling tank, and the oil and gas are turned into liquid oil after the water is cooled. Oil is yellow when it first comes out, but it will soon turn black. In order to be able to fake the truth, these diesel must go through the last process before they leave the factory, namely, bleaching, also known as washing oil. After these three processes, the waste oil becomes diesel fuel.
Decolorization of 3. black diesel
Black diesel oil is the residue of Refinery after refining, or the disqualified diesel produced by small refineries. The sulfur content and acidity of this kind of oil are far beyond the normal diesel, and can not be used for motor vehicles. As the oil price is cheap, some unqualified underground refineries will be able to add decolorizing sand and decolorant to turn black diesel into light yellow or jujube red, and then sell to private gas stations and black refueling stations through abnormal channels. Because the decolorizer used is not very good, this kind of diesel oil and air contact after two or three months, will be "hit back to the original" and re-black.
4. heavy firewood, kerosene, carbon nine, and plastic oil blending
Some illegal black processing plants will also buy heavy diesel, waste kerosene, carbon nine, plastic oil and other raw materials, blending into inferior mixed oil according to a certain proportion, and then blending some additives into false diesel.
Because of the low price of counterfeit diesel, private gas stations, Rural gas stations, black gas stations, black gas trucks are often the main places to sell such diesel.
Fake diesel is very beautiful from its appearance, but its composition is much different from that of diesel oil, and its sulphur content and acidity are very large. Fake diesel can not be completely burned in the engine, which is likely to cause carbon deposition, black smoke and engine power shortage. Long term use of diesel oil with high acidity will cause great corrosion to automobile engines. The composition of fake diesel is complex, and more harmful substances will be produced after combustion, which will cause great harm to the environment.
Post language:
Fake diesel is cheap, but not fully burned, fuel consumption is relatively high, and it is particularly harmful to vehicles and the environment. Hope that cardholders usually open their eyes, when choosing a large gas station, do not covet small and cheap, or eventually spend money to repair the car is worthwhile.
