With the development of the world, diesel and gasoline vehicles have become an important part of modern transportation. However, compared to gasoline cars, SUV Ranking Network (www.270top.The special requirement that urea needs to be added to diesel vehicles often confuses many car owners. So, why do diesel cars need to add urea?
Why do diesel vehicles need urea to neutralize nitrogen oxides?Urea is a compound containing elements such as nitrogen, oxygen, hydrogen, etc., and its chemical formula is CO(NH2)2. At high temperatures, urea decomposes to produce ammonia and carbon dioxide. When ammonia gas is combined with nitrogen oxides, harmless nitrogen and water vapor are formed. In this way, by adding urea, diesel vehicles can convert nitrogen oxides into harmless substances, thereby reducing their pollution to the environment.
In addition to urea, diesel vehicles also need to pay attention to other aspects of maintenance. For example, replace air filters, fuel filters and other accessories regularly to ensure the normal operation of the engine. At the same time, the owner also needs to pay attention to the driving condition of the vehicle, and if an abnormal situation is found, it should be dealt with in time.
