The role of car urea solution

I believe everyone is a little unfamiliar with vehicle urea (only for diesel vehicles). After all, environmental protection emissions are becoming stricter and stricter. Diesel vehicles will naturally decrease. Basically, some large trucks and trucks use diesel. It's normal to be unfamiliar with car urea. So let's give you a popular science, the role of car urea solution.

Vehicle urea can be used in the selective catalytic reduction (SCR) system of diesel vehicle exhaust to catalytically reduce the nitrogen oxides (NOx) in the exhaust gas to harmless nitrogen (N2) and water (H₂O) for discharge. Reduce the nitrogen oxides in the exhaust gas of the diesel engine, so as to achieve the effect of energy saving and environmental protection.

But it should be noted that usually we can see the car urea margin on the car instrument. When the margin is lower than 20%, we must add car urea as soon as possible to avoid lack of car urea when driving. , Otherwise the system will limit the operation of the engine, and exhaust pollution will become more serious.

Then some friends will ask whether car urea is harmful to the human body. First of all, car urea is actually made of 32.5% high-purity urea and 67.5% deionized water. We must know that our body itself produces urea, so contact with the body will not cause any impact. However, under high temperature conditions, car urea will easily release ammonia gas, and ammonia gas has a certain corrosive effect. If it contacts the skin for a long time, it is likely to cause pigmentation or ulcers. So when we come into contact with car urea, we should rinse with clean water as soon as possible.
