Adblue Fluid

Adblue Fluid

What is Adblue Fluid ?

AdBlue is a fluid used in many modern diesel cars. If your vehicle utilises AdBlue, you’ll most likely need to top it off at least once between service visits. Learn what it does, how it works, and why it’s vital to pay attention to dashboard alerts, especially if you drive a lot. AdBlue reduces harmful emissions – but if you run out, your car won’t start.

AdBlue is an exhaust fluid, not a fuel additive. It’s kept in a separate reservoir and filled off using a (typically) blue filler cap found next to the gasoline filler, in the trunk, or under the hood. It’s a registered trademark of the German Automobile Manufacturers Association, yet it’s the most well-known type of Diesel Exhaust Fluid (DEF).

What is AdBlue Fluid and how it works?

AdBlue is a colorless liquid that is made from a mixture of high-purity urea and deionized water. The solution is an essential component of selective catalytic reduction (SCR) technology, which is one of the most effective systems because it reducing the nitrogen oxide (NOx) levels in the exhaust fumes that exit diesel engines. NOx is one of the most harmful pollutants emitted by engines as  it reacts with other gases in the atmosphere to form small particles and ozone, both of which can damage sensitive lung tissue in humans and animals.

When the fuel is burned by the engine, AdBlue is injected into the SCR catalyst in order to convert the NOx into a less harmful mixture of nitrogen and water vapor. The solution is stored in its own tank, separate from the diesel, before being added to outgoing exhaust gas by a dosing control system that supplies enough AdBlue to make up 2–6% of the total fuel consumption. In the SCR catalytic converter, the urea present becomes ammonia when heated, reacting with the NOx in the emissions to convert the pollutants into nitrogen, water, and a small amount of carbon dioxide.

What happens if I run out of AdBlue?

If you run out of AdBlue while driving, the engine’s power and performance will be decreased to keep emissions to a minimum. If the AdBlue tank is empty when you stop, you won’t be able to restart the engine.
When the AdBlue tank is low, the automobile will give you plenty of notice. At about 1500 miles, you’ll get a text warning on the dashboard, followed by an amber caution light. Ad Blue fluid is available at our outlet.

Which cars can use AdBlue?

AdBlue technology isn’t used by all automakers. If you have a diesel from Jaguar, Land Rover, or any other French or German brand that was registered new after September 2015, it’ll almost certainly employ AdBlue.

Does my car use AdBlue?

AdBlue is also used in some older automobiles and vehicles made by other automakers. If you’re not sure if your automobile utilizes it, look at the following:

  • The vehicle handbook.
  • See if there’s an AdBlue filler cap either next to the fuel filler, in the boot, or under the bonnet.
  • If the model name contains ‘Blue’ or ‘SCR’.
  • If you’re still not sure, ask a dealer.

The following makes and models of cars mostly manufactured after 2015 require Adblue, DEF, and AUS32.

  • Audi
  • VW
  • BMW
  • Mercedes
  • GMC
  • Toyota

How long does AdBlue last?

The amount of AdBlue you use is determined by your engine and how efficiently you drive.

  • Every 600 miles, an average of a litre of AdBlue is used.
  • However, it might be up to a litre every 350 miles.
  • Tank sizes vary, so depending on the automobile and your driving style, you may need to replenish between 3,000 and 12,000 miles.

This implies that most drivers will need to top up their Ad Blue reservoir at least once in between regular dealer visits.

Some of the Ad blue standards are

  • GUS052910A3
  • BMW 83-19-0-441-139

Is driving with the AdBlue warning light on safe?

It’s not a life-threatening situation, but if you don’t top up, you’ll soon run out of AdBlue and be unable to start the car. The car may go into limp mode, which means low power output and decreased top speed.
Don’t panic if the warning light comes on for the first time. You’ll have plenty of time to replenish. Just make sure you don’t wait too long to top up, especially if you’re due for a MOT. The emissions of your car will be examined as part of the MOT; not having enough AdBlue might cause them to rise to harmful levels.

AdBlue and SCR systems are highly effective, They reduce the NOx emissions by up to 90%, hydrocarbon and carbon monoxide emissions by 50-90%, and particulate emissions by 30-50%.

Where is the AdBlue tank?

The AdBlue tank is normally found underneath the boot floor, where the spare wheel used to reside. However, knowing where the filling for it is situated is more vital.
A little blue filler cap is frequently seen adjacent to the main diesel filler. If it’s not there, look under the trunk or beneath the hood.

DENSO Introduced the common-rail diesel system primarily to bring down NOx levels and black diesel smoke with Adblue fluid. The primary features of this system are

  • Improved Fuel economy
  • Noise Reduction
  • High Power output

The common-rail system meets the Step 3 (Euro3) stage of the European Emission regulations and with some minor improvements in DPF (Diesel Particulate Filter) , implementation of AdBlue.



Emission Components

All modern clean diesel engines have 3 major emission components

  • DPF (Diesel Particulate Filter)
  • NOX catalyst (with or without Adblue)
  • Oxidation catalytic converter

What is DPF?

A diesel particulate filter (DPF) is a filter that captures and stores exhaust soot and the primary function is to reduce emissions from diesel cars. Because they can choke easily due to soot formation. They need to emptied or periodically cleaned. This is termed as regeneration of DPF. This was introduced as a Euro 5 exhaust emission regulation and in some countries it is illegal to remove it permanently from the exhaust system. DPF have shown to cause drivers a lot of problems because, if the cleaning process in interrupted.

If DPF is blocked / clogged you may see this light turned on the Instruments Cluster.


Symptoms of a choked DPF

You may get following symptoms if the On-board system is cleaning DPF automatically

  • Change in Engine Sound
  • Running of cooling fans
  • Increase in Fuel consumption
  • Increase in idle speed
  • Exhaust Smell

Adblue Injection

Adblue injection occurs through a high speed pulsating injector module that is electronically driven and adjusted according to the demand of the emissions control system. It is also called a dosing module and comes along with a dozer pump module. All of these components are very delicate and can create lots of problems specially in extreme winters and summers.

Back to 1KD and 2KD overview

These engines are exceptionally quiet and provide a great torque at lower RPM,s as well, thanks to the on-board Computer controlled fuel pressure and injection timings through the ID matched injectors. The engines have shown up-to 20% better throttle response and fuel average. Popular models in Pakistan having 1KD and 2KD engines are Toyota Vigo Thailand and Invincible (UK), Vigo Champ Pakistan and Toyota Hiace vehicles. So, These engines mostly have an inter-cooler and all have a Turbo.

1KD and 2KD run smoother because of injection of a pilot charge in cylinders using the same injectors. A pilot charge is a spray of a diesel before the spray of the main fuel that assist in complete combustion of the diesel fuel.
