Rejection of nitrogen oxide emissions from Meifengjia Blue no longer makes trucks a source of pollution

The internal combustion engine achieves power and fuel economy through optimized combustion, but the only drawback is that high temperature combustion produces a large amount of nitrogen oxides to be discharged. This is an inevitable phenomenon, and the fact that it cannot be changed can only be chemically decomposed by ammonia in vehicle urea. It becomes harmless nitrogen and water. If the SCR system stops operating, it is the driver group that generates the most nitrogen oxide gas first. Nitrous oxides are colorless, odorless and have little toxicity, but high concentrations can cause nerve center licking and spasm, and nitrogen oxides are gradually oxidized to NO2 after being discharged into the atmosphere. NO2 is a pungent odor and toxicity. Very red-brown gas (which is about 5 times more toxic than nitrogen oxides) can cause damage to the human respiratory tract and lungs, and can cause emphysema when severe.

Because the system does not work for a long time, the urea pump may be stuck or corroded due to the crystallization of the residual urea solution. The urea nozzle is working in a high-temperature environment, and the urea solution will not be cooled for a long time. Burning damage. Facts have proved that the money saved from buying carbamide for a year will not be enough to repair it to meet the annual inspection.

The engine electronic control system of the vehicle is designed to set relevant procedures for the emission. A variety of sensors are also installed on the exhaust system to collect relevant signals and feedback to the ECU (engine computer version). After the SCR system stops working, the computer receives The arrival signal must also be flawed with the procedures set by the engineers. In order to reduce emissions, the computer program will naturally correct itself. The measured data show that the fuel consumption will increase 3-5%, the power will decrease by 10-20%, and some vehicles will even be more High, the calculation is still not worth the candle, one month down will feel no urea more than urea increases fuel consumption.

It may be said by everyone that environmental protection is not a matter for me. What does it have to do with me? But have you ever thought that the environment is getting worse and worse today, and the haze has made us have problems in traveling. If this continues, If the London fog did not reach the five fingers away from us, it is understood that automobile emissions account for 30.4% of all sources of pollution, and a truck that does not burn urea emits several hundred times or even thousands of times more harmful gas than a family car.

Regarding the use of vehicle urea, whether it is from an economic perspective or an environmental perspective, we should all look at it correctly.

UFC Blue Car urea has always been the industry leader, consisting of 32.5% high-purity urea and 67.5% ultra-pure water. It is colorless, transparent, non-toxic, alkaline (corrosive), and has a pH of 10, The best storage temperature: 25 °C - 5 °C. It evaporates slightly at high temperatures, and crystallizes below -11.5°C. AdBlue® ensures nitrogen oxide emission control. Below the value specified by the National IV emission standard, it is an environmental protection just-in-demand product with a SCR system diesel commercial vehicle, which is a necessity for reducing PM2.5!
