Summary

adblue use, filling, storage

AdBlue plays a central role in reducing emissions from modern diesel engines, as the aqueous urea solution helps to effectively reduce harmful nitrogen oxides in the SCR system. A AdBlue tankwhether in CAR, in the TRUCK or as an external AdBlue tank systemensures that sufficient fluid is available at all times for optimum engine and exhaust performance. It is becoming increasingly important for companies to store AdBlue safely, fill it efficiently and keep an eye on stocks. Intelligent monitoring is becoming increasingly important. This is exactly where Four Data comes in: With smart IoT sensors and a modern platform we create full transparency about your tanks by making your tanks more transparent, safer and more economical.

What is an AdBlue tank?

An AdBlue tank is a specially developed container for the safe storage and supply of AdBlue, an aqueous urea aqueous urea solutionwhich is used in modern diesel vehicles to reduce nitrogen oxides. In a PASSENGER CAR, TRUCK or a stationary AdBlue tank system guarantees the tank guarantees that sufficient AdBlue is available at all times for precise injection and optimum functioning of the SCR system. In addition to being used directly in the vehicle, external AdBlue tanks play a central role in workshops, businesses and fleetswhere large quantities need to be stored and refilled efficiently. The quality and purity of the medium is crucial, as impurities can cause damage to the SCR system. Because with a professional AdBlue tank and the right monitoring solution, safety, logistical efficiency and operating costs can be noticeably improved.

Function in the SCR system

The SCR system (Selective Catalytic Reduction) uses AdBlue to effectively reduce harmful nitrogen oxides (NOx). The fluid is injected into the hot exhaust gas stream in precisely metered quantities, where it decomposes and converts NOx in the catalytic converter into harmless nitrogen (N₂) and water vapor (H₂O) converted. So that these chemical reaction reliably takes placethe AdBlue tank must always have the correct filling quantitytemperature and purity at all times. As a central element of the entire SCR system, it directly influences the performance of the emission reduction and therefore makes a significant contribution to lower exhaust gas values and greater operational safety.

Myth versus reality
AdBlue does not improve engine performance – it only reduces emissions.

Structure and typical components

  • Tank container (HDPE or metal, depending on the application)
  • sensors for measuring fill level, temperature and quality
  • Piping system between tank and dosing module
  • Filler neck for canisters, dispensers or mobile systems
  • heatingto avoid crystallization at low temperatures

HDPE is often used because it is corrosion resistant and suitable for urea solution is suitable. Metal is mainly found in large systems.

Differences between vehicle tank and external tank systems

A vehicle tank and an external AdBlue tank system fulfill different tasks and are therefore dimensioned and designed differently:

Criterion Vehicle External system
volume approx. 8-30 liters approx. 200-10,000+ liters
Utilization Supply of a vehicle in driving mode Storage and supply of several vehicles / fleets
Mobility Permanently installed in the vehicle Available as a stationary or mobile solution

Refill AdBlue correctly

When does AdBlue need to be topped up?

The optimal time to refilling AdBlue depends on the vehicle type. Cars usually display a warning symbol on the display and show a Remaining range in kilometers on. In the case of trucks, the warning is issued earlier as consumption is higher. Typical indications:

  • Yellow or red warning message
  • Message “AdBlue level low”
  • Noticeable reduction in the remaining range

Step-by-step instructions for filling

Correct refueling ensures to ensure that the vehicle works reliably and the SCR system remains protected. This is how you proceed:

Checklist

  1. Vehicle safely and switch off the switch off the engine.
  2. Tank cap of the AdBlue tank.
  3. Canister, dispenser or mobile pump attach.
  4. Fill in AdBlue slowly and check the check the filling quantity.
  5. Close the lid and make sure it is clean.

Practical tip: Use gloves and a funnelto avoid soiling and make filling easier.

Common mistakes when refilling and how to avoid them

Typical errors occurwhen AdBlue is stored incorrectly or not properly filled is filled. The most common points:

  • Wrong opening caught (confusion with the diesel tank)
  • Overfilling due to filling too quickly
  • Contamination due to unsuitable canisters
  • Filling at extreme temperatures

Common errors : Inadvertently filling AdBlue into the diesel tank.

What happens if you continue driving without AdBlue?

If the AdBlue tank runs low, the vehicle automatically reduces engine power. Modern systems even block the engine start when the tank is completely empty to prevent damage. A Timely refilling is therefore important to avoid breakdowns and repairs.

Costs, consumption & sources of supply

AdBlue consumption by vehicle type

The AdBlue consumption depends heavily on the vehicle and the motor load. With PASSENGER CAR is consumption on average 1-2 % of the diesel consumptionwhile TRUCKS due to larger engines and higher loads up to 6 % are required.

Comparison table :

Vehicle type Consumption Ø
PASSENGER CAR 1-2 % of diesel consumption
TRUCKS up to 6 %

Key figures : 1,000 km ≈ 1 liter AdBlue (passenger car Ø).

Prices and cost factors

The prices vary depending on the source of supply and container size. Decisive are above all Quality, price per literstorage and transportation.

Price range (standard values) :

  • Petrol station : higher price per liter

FAQ about AdBlue tanks

An AdBlue tank is a special container for the safe storage of the aqueous urea solution. aqueous urea solutionused in the SCR system to reduce nitrogen oxides. used becomes. It ensures that at all times sufficient medium is available for injection.

Consumption depends on the vehicle in question. On average, cars need a refill every 5,000-10,000 kilometers, while trucks need to fill up with AdBlue much more frequently due to their higher consumption. Vehicles issue warning messages on the display in good time so that refilling can be planned without any problems.

Make sure that you only use approved AdBlue, select the correct filler neck and contamination avoid contamination. Fill the tank slowly to prevent overfilling. After refueling the Close the tank cap carefully and keep the surrounding area clean.

If the AdBlue supply runs low, the vehicle initially reduces the engine power. In many cases, the system prevents a restart when the tank is completely empty. Timely refueling avoids breakdowns and unnecessary workshop visits.
