Can a diesel vehicle operate normally without urea?
1 Answers
Diesel vehicles can operate normally without urea, but this will have negative effects on the vehicle. The primary purpose of adding urea is to reduce nitrogen oxide emissions. While omitting urea won't directly affect the engine, it will cause emissions to exceed standards and pollute the environment. Prolonged non-use of urea will lead to rapid oxidation of chemicals in the diesel vehicle's system and clogging of the urea injector, potentially rendering the entire system inoperable. Here's an introduction to automotive urea: 1. Origin: Automotive urea solution was first used in Europe, where it's called AdBlue. In North America, it's known as DEF (Diesel Exhaust Fluid), while in China it's referred to as automotive urea solution or "automotive denitration agent." Currently, it's generally called "automotive urea" in China. 2. Function: Automotive urea solution is crucial for reducing pollutant emissions from diesel vehicles. This urea-based chemical reagent, composed of high-purity urea and deionized water in a 32.5% concentration solution, is essential for SCR systems to help diesel engines meet China IV and higher emission standards.
