What happens if a truck runs without urea?

[VincentRose]

Truck torque will be limited to some extent without urea, but it can still continue to drive. Urea is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Urea is composed of 67.5% deionized water and 32.5% high-purity urea. Additional information: 1. Urea injection is for diesel engine vehicles, as diesel engines emit harmful nitrogen oxide gases that cause environmental pollution. 2. Long-term inhalation of vehicle exhaust by humans can cause significant harm to the body. To reduce such hazards, it is necessary to use urea in diesel engine vehicles. 3. Urea has a catalytic function. When it encounters nitrogen oxides, it causes a chemical reaction, converting nitrogen oxides into nitrogen and water before being discharged.
