Differences Between Vehicles That Use Urea and Those That Don't

[VanAurora]

Vehicles that use urea will experience engine torque limitation, reduced horsepower, and increased fuel consumption if urea is not used. Prolonged absence of urea can lead to partial or complete system damage, resulting in costly repairs, so it's advisable to address the issue promptly. Not all vehicles require urea; currently, only diesel engines do. The hazards of not using urea are as follows: 1. Environmental Pollution: Diesel vehicles without urea can have a severely negative impact on the ecological environment, which is also against national laws and regulations. 2. Damage to the SCR Injection System: Prolonged absence of urea may cause crystallization and blockage in the SCR system's nozzles, pipelines, and urea pump, or damage due to high temperatures. 3. Reduced Power: This is not a direct result of not using urea, but rather because the engine's electronic control system forcibly limits torque output when it detects no urea injection and excessive tailpipe emissions.
