What happens if a truck runs without urea?

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.
I once experienced the embarrassment of running out of urea on the highway. Suddenly, a yellow warning light popped up on the dashboard, the speed was limited to 60 km/h, and the engine sound became very dull. The service station mechanic said that after the SCR system stopped working, the exhaust treatment completely failed, and the worst part was that the vehicle system would forcibly reduce speed. Not only was I honked at by the trucks behind me, but I also had to worry about being caught for excessive exhaust emissions. For National V and VI models, the maximum fine is 5,000 yuan. Now I always keep two barrels in the back compartment. After all, compared to fines and repairing the exhaust pipe, the cost of urea is really nothing.
