Can the car run without urea?
1 Answers
The car can continue to run without urea, but it needs to be replenished as soon as possible. Prolonged lack of urea in the car will cause the following impacts: 1. The urea pump nozzle, pipelines, and urea pump are prone to crystallization blockage or high-temperature damage. 2. The emission light will turn on, torque will be limited, leading to insufficient power, making the car feel sluggish. 3. Trucks without added urea will fail the annual inspection and may face penalties. The role of urea in vehicles: 1. First, adding urea is for diesel engine vehicles because diesel engines emit harmful nitrogen oxide gases, causing environmental pollution. Long-term inhalation of these exhaust gases can cause significant harm to humans. To reduce this hazard, vehicles with diesel engines need to add urea, which has a catalytic function. When encountering nitrogen oxides, it triggers a chemical reaction, converting nitrogen oxides into nitrogen and water, which are then emitted. 2. With stricter vehicle emission standards, automotive urea has become the fourth largest automotive consumable after fuel, lubricants, and tires. 3. Qualified urea solution is synthesized from 32.5% ultra-pure urea and pure water. Automotive urea solution reacts with nitrogen oxides through selective catalytic reduction, converting them into nitrogen, oxygen, and water, thereby reducing nitrogen oxide emissions. 4. Automotive urea plays a critical role in vehicle power and fuel consumption. If diesel exhaust fluid is not loaded, or if urea solution with insufficient purity or poor quality is used, it will cause the vehicle's engine to automatically decelerate. At the same time, poor-quality diesel exhaust fluid can pollute the SCR catalytic reaction tank's catalyst, causing damage to the post-processing system components.
