What is the function of truck urea solution?

[SiennaAnn]

Urea solution for vehicles is used to reduce harmful nitrogen oxides in exhaust gases into nitrogen and water. Here is some relevant information about vehicle urea: 1. Principle: Technical means can be employed inside the engine to reduce particulate emissions, leaving mainly nitrogen oxides in the exhaust. By injecting urea into the exhaust after-treatment device, the urea decomposes into ammonia at high temperatures, which reacts with nitrogen oxides under the action of a catalyst to produce harmless nitrogen and water. This device is called the SCR (Selective Catalytic Reduction) after-treatment system. 2. Impact of not using vehicle urea: It causes environmental pollution; the chemicals in the diesel vehicle system will quickly oxidize, the urea nozzle will become clogged, and the entire system may be rendered useless; due to the OBD's torque limitation function, vehicles without urea will experience reduced power performance.
