The length of truck 315 knowledge article says "no" to urea in fake cars

The recently very popular documentary “Under the Dome” has exposed some key sources of haze, one of which was tested in Beijing. As a major source of local pollution, the impact of diesel vehicles on haze is much higher Cars have become a major factor in the emission of motor vehicle exhaust pollution. In the previous issue of “3.15 Long Knowledge,” we focused on the impact of the “Fake Country IV ” diesel vehicle, which mentioned the issue of vehicle urea. In this issue, we’re going to give you a detailed introduction and another environmental killer. The effect of fake urea on our environment.

Real and fake urea are different

From the announcement issued by the Ministry of Industry and Information Technology, starting on January 1, 2015, China will implement a national IV emission standard for diesel vehicles, and vehicle urea will also slowly move into the attention of everyone. China Truck Network has popularized vehicle urea for everyone. Knowledge, the introduction of a series of articles and topics, so the specific vehicle urea knowledge you can click on the link to view, Xiao Bian will not tell you what is car urea. " You don't understand car urea ."

The urea solution for vehicles is an indispensable standard configuration for qualified national IV heavy-duty diesel vehicles. Like diesel, it is a continuation consumable and is stored in a urea tank specially configured for the National IV diesel vehicle. Its usage is generally small. It is equivalent to 3% to 5% of diesel consumption. In other words, a heavy-duty diesel vehicle with a fuel consumption of 40 liters per year driving 100,000 kilometers and 100 kilometers per year should normally consume between one and two tons of urea solution for vehicle use.

Why is car urea important? Car urea plays an important role in the treatment of exhaust gas in diesel vehicles as a whole. The continuous increase in nitrogen oxides accelerates the formation of ozone and secondary aerosols, and is an important precipitating factor for hazy weather.

Therefore, qualified vehicle urea is the key barrier to ensure that the country's four diesel vehicle emissions can truly meet the national emission standards. Once fraud occurs at this stage, even if the car's hardware standards are higher, it will not help.

Urea falsification

China's automotive urea industry started from around 2008. According to the China Truck Network, a well-known Chinese urea company has faced the dilemma of “bad money drives out good money” in the face of the impact of counterfeit products. The person in charge of the company mentioned: “It is not just the impact of many non-compliance vehicle urea products that have plagued us since the second half of last year on the market. From the perspective of the driver, of course, it is saving money, but From the emission control point of view, this will completely overturn the National 4 standard. If this continues, where will the smog control begin?”

Some unscrupulous traders in the industry use agricultural urea instead of industrial urea to blend into urea solutions for vehicles, strengthen the supervision of urea production for vehicles, measure the concentration of urea products, and regulate the management of vehicle urea in the market; in addition, customers themselves It is necessary to strengthen the identification of genuine and fake vehicles urea. Strengthening the supervision of the automotive urea industry is the most crucial factor in regulating the automotive urea industry.

Fight against fake urea in the end

For the long-term use of fake urea or so-called "retrofit" of the National Diesel, although it can save some of the cost of urea, but also for the truck itself and the environment, it also has a great impact, often using fake urea cars, When the purity of urea is not up to the standard, particulates or heavy metal ions may cause serious damage to the nozzles, filters, and other components of the SCR system of the vehicle and reduce the service life.

If this phenomenon is not effectively curbed, it will bring endless scourge to our haze governance - thousands of seemingly qualified "National IV" diesel vehicles, which actually exceed the standard hundreds of times the nitrogen oxides Emissions, which travel day and night on the roads of the land of China, are equivalent to moving “gas canisters”. Once they are allowed to continue their development, they will make it difficult to begin fully implementing the four emission standards for diesel vehicles. Large-scale investment in motor vehicle exhaust gas control campaigns will also face the danger of losing power due to a small amount of urea.

We do not buy fake urea. He will destroy it on his own. We will abide by laws and regulations and the environment will be better every day. Your heart is my heart and soul, and you walk in the line of yours. In this battle full of smoke but no gunfire, we must walk hand in hand. We have no way out.
