Common Damages When Using Substandard AdBlue Solution

AdBlue is a solution containing urea (32.5%) and purified water used in diesel vehicles with SCR (Selective Catalytic Reduction) systems. The main purpose of AdBlue is to reduce NOx emissions that pollute the environment. However, if AdBlue is not up to standard, serious problems can occur with the SCR system and the vehicle's engine. This article will discuss common failures when using poor quality AdBlue.

 

What is poor quality urea?

 Concept

"Low-quality urea water" refers to urea products that fail to meet quality standards or contain undesirable impurities. Standard Urea/AdBlue solutions that comply with Euro 4-5-6 regulations typically have a urea concentration of approximately 32.5% and are highly pure, free of significant contaminants such as salts, heavy metals, or other unwanted compounds. Impurities can reduce the solution's effectiveness or harm the environment and crops.

The urea concentration in exhaust treatment solutions, whether too high or too low, can directly impact your vehicle's engine. The standard 32.5% concentration is the optimal composition, ensuring your car operates efficiently across various terrains while minimizing energy consumption and travel costs. Using urea water prepared at the appropriate temperature and with the proper composition is essential for protecting your vehicle and avoiding engine damage.

 

Indicators

Below are some signs that may indicate low-quality automotive exhaust treatment solutions:

• Color Change: High-quality urea water solutions are typically clear or light blue. If the solution has an unusual color, such as brown, dark yellow, or appears cloudy, it could indicate contamination or substandard blending.

• Unusual Odor: Exhaust treatment solutions should not have strange odors. A strong chemical or foul smell may suggest contamination or poor-quality production.

• Crystals or Sediments: Premium AdBlue solutions should be free of residues or crystals. The presence of sediment indicates degradation or improper mixing with unsuitable substances.

• Increased Consumption: If there is an abnormal rise in the consumption of the exhaust treatment solution, it could result from low-quality products that fail to effectively reduce NOx emissions.

• Warning Systems: Many engine management and exhaust treatment systems can detect substandard solution quality. If warning signals or error lights appear on the dashboard, it may indicate the use of a non-compliant solution.

• Poor Engine Performance: Low-quality solutions can lead to reduced engine performance, increased emissions, or malfunctions in the Selective Catalytic Reduction (SCR) system.

• Failed Emission Tests: If the engine fails emission tests or inspections, it might be due to the use of substandard exhaust treatment solutions.

Permanent damage

SCR system blockage

Substandard AdBlue solution may contain impurities or residues, causing the injector or filter of the SCR system to become clogged.

In this case:The urea injection process is interrupted, reducing the efficiency of NOx treatment.The catalytic converter may be damaged due to residue accumulation.
Consequences:The vehicle may not meet emission standards, and the warning system may be activated, requiring urgent maintenance.

Corrosion and failure of the AdBlue pump

Standard AdBlue must be mixed with deionized water, if using a type with impurities or incorrect ingredients, system components such as pumps and injectors will be susceptible to corrosion or wear.
Symptoms:
The AdBlue pump may make strange noises or operate poorly.
The injector does not provide the required amount of solution.

 

NOx sensor and error warning

When AdBlue does not convert into ammonia as expected, the NOx sensors in the SCR system fail to measure emissions accurately. This can result in:

• Frequent error alerts even when emissions are within permissible limits.
• The vehicle entering limp mode (power restriction mode) to protect the engine.

 Increased Maintenance Costs and Downtime

Low-quality AdBlue can damage various components, forcing vehicle owners to:

• Replace filters, pumps, or the SCR system, which can be costly.
• Experience reduced vehicle uptime due to frequent trips to the garage for repairs.

 

---

Non-Compliance with Emission Standards and Penalties

If the SCR system malfunctions, NOx emissions may exceed regulatory limits. This could result in:

• Failing emission tests.
• Administrative fines for violating environmental regulations.

 

---

Risk of Crystallization and Deposits in the System

Impure AdBlue may cause crystallization or deposits to form inside pipes and injectors. These crystals can block the solution's flow, leading to system failure.

Solutions and Best Practices for Using AdBlue

• Purchase AdBlue from reputable sources with ISO 22241 certification to ensure quality.
• Avoid long-term storage as improper storage can degrade the solution.
• Perform regular inspections and cleaning of the SCR system to ensure stable operation.
• Do not dilute or mix AdBlue with other chemicals.
