What is the purpose of adding urea solution to diesel vehicles?
2 Answers
Adding urea solution to diesel vehicles serves to reduce nitrogen oxides in vehicle exhaust, decrease emission pollution, and enhance the environmental friendliness of the vehicle. Urea solution is primarily used in cars, trucks, buses, and heavy-duty non-road diesel engine vehicles equipped with SCR (Selective Catalytic Reduction) exhaust treatment systems. It helps purify vehicle exhaust and reduce the emission of nitrogen oxides. The main harmful substances in diesel vehicle exhaust are nitrogen oxides and particulate matter, which can be reduced inside the engine through technical means. Automotive urea, also known as diesel exhaust fluid (DEF), is crucial for reducing nitrogen oxide compounds in vehicle exhaust and lowering the emission of pollutants from diesel vehicles.
I've been driving diesel trucks for over a decade and have deep feelings about the urea fluid refill. It helps reduce black smoke and harmful gases from the exhaust pipe, mainly those nitrogen oxide things, converting them into harmless water and nitrogen. I remember once when I forgot to refill it, got pulled over for an environmental inspection on the road, was fined heavily, and noticed the engine didn't run smoothly. Long-term neglect can shorten the vehicle's lifespan and increase maintenance costs. Now I always check the urea fluid level whenever I fill up the fuel tank – most gas stations have refill points, which is quite convenient. This stuff is crucial for air purification, especially when driving in urban areas. Meeting emission standards helps reduce pollution, allowing everyone to breathe healthier air and avoiding being stopped during roadside inspections.
