How Does AdBlue Work In A Diesel Engine?

AdBlue is a chemical that is added to your exhaust and reacts with the gases that your vehicle creates. It breaks down the harmful nitrogen oxide gas (NOx gas) produced by your engine into harmless nitrogen and water vapour.

NOx emissions contribute to the creation of particulate matter, smog, acid rain, and ground-level ozone, as well as causing respiratory difficulties.

Vehicles must meet tight exhaust emission restrictions, and the most recent standard, Euro 6, is particularly demanding in terms of NOx limitations.

Most cars can only meet the Euro 6 criteria if they have SCR (Selective Catalytic Reduction) technology installed (SCR). AdBlue is used in this technique to break down and reduce hazardous pollutants.

What does AdBlue do to a diesel engine?

AdBlue is a non-toxic diesel exhaust fluid made composed of high purity urea and deionized water that is used to minimize hazardous emissions from diesel engines. It has no odor and is non-toxic, however it can corrode metal surfaces.

Where does AdBlue get injected?

AdBlue is pumped into the exhaust pipe, which is in front of the SCR catalyst but downstream of the engine, from the vehicle’s specific AdBlue storage tank. AdBlue degrades into ammonia (NH3) and carbon dioxide as it heats up in the exhaust (CO2). When NOx fumes from the exhaust pipe react with ammonia inside the catalyst, the dangerous NOx molecules in the exhaust are transformed to harmless nitrogen and water, which is then discharged into the atmosphere as steam.

What happens when you run out of AdBlue?

What happens if you run out of AdBlue in your car? If you run out of AdBlue while driving, the engine’s power and performance will be lowered to ‘limp home’ mode to decrease emissions, and the engine will not start again until the AdBlue tank is replaced.

Is AdBlue made from pigs urine?

Is AdBlue created from the pee of pigs? AdBlue is a highly pure synthetic urea and demineralized water solution, not pig urine. While urea is present in pig urine, it is present in considerably lower concentrations than many other components.

Can Diesels run without AdBlue?

By breaking down dangerous nitrogen oxides, AdBlue helps newer-model diesel vehicles fulfill emissions limits. If you have an AdBlue tank in your diesel automobile, the engine is programmed not to start after you run out of it.

The good news is that one litre of AdBlue can get a car to travel over 1,000 kilometers. Cars usually have tanks that store at least 10 litres of fuel. So a single tank should last you at least six months.

It’s a different story for trucks. They often travel longer distances and are less fuel efficient, consuming roughly 1 litre of AdBlue every 70 kilometers.

Due to their age, about half of Australia’s trucks do not use AdBlue. Australia’s truck fleet is 15 years old on average, compared to 13 years in Europe and less than 10 years in Germany. Furthermore, Australian emission regulations are less strict than those in the European Union.

We may have to rely on these older trucks in the worst-case scenario, if no solution is discovered and AdBlue supply runs out. Newer trucks could be reprogrammed to emit far more pollution. However, this is a challenging technical challenge that will necessitate temporary adjustments to Australian emission limits.

That is a path that no one wants to go. As a result, the federal government has formed a taskforce to address the issue.

Can a diesel car run without 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 warning. At about 1500 miles, you’ll see a text warning on the dashboard, followed by an amber caution light.

Can you bypass the AdBlue system?

Repairing the adblue system (SCR system) will set you back thousands of dollars. After repair, there is no guarantee that it will work without problems; in most cases, they will fail within 6-8 months. The only option is to replace, which is more expensive than repairing.

You can make adblue bypass and use your truck or automobile without adblue def fuel using adblue delete. Adblue elimination software and emulators are used for this.

Can I use water instead of AdBlue?

AdBlue is a regulatory requirement for vehicles equipped with Selective Catalytic Reduction technology and can be found in trucks, buses, cars, vans, boats, excavators, and tractors, among other things. With over 23,000 reported breakdowns due to inadvertent misuse or a lack of knowledge of AdBlue’s use each year, it’s critical to understand why we need AdBlue and how we can utilize it effectively.

What is the purpose of AdBlue?

To meet Euro 5 and Euro 6 pollution requirements, any diesel vehicle equipped with Selective Catalytic Reduction (SCR) technology requires AdBlue. AdBlue is a reducing chemical used in the SCR system to convert dangerous Nitrous Oxide into harmless Nitrogen and Water, resulting in less pollution.

How do I know if my vehicle needs AdBlue?

AdBlue should only be used in diesel vehicles equipped with a selective catalytic reduction (SCR) system. It’s worth looking for an AdBlue filler cap next to the petrol filler, in the trunk, or under the hood of your vehicle.

You can use the model name to see if your vehicle needs AdBlue. The letters ‘SCR’ or ‘Blue’ may appear on the vehicle’s model, suggesting the requirement for AdBlue. The more recent a diesel vehicle is, the more probable it is to require AdBlue. If in doubt, consult the vehicle owner’s manual or ask the dealer where you purchased the vehicle.

What should I know about using AdBlue?

Using water instead of AdBlue – In a nutshell, you must not use water in place of AdBlue or dilute it in any way. AdBlue is made up of 67.5 percent de-ionized water and urea. Tap water, on the other hand, includes a high concentration of minerals and ions that can affect the car exhaust treatment system.

AdBlue is widely misunderstood as a fuel additive, however it is actually an exhaust fluid that should never be mixed with diesel. Putting AdBlue in your fuel tank can harm your tank, pump, and injection system for thousands of pounds. AdBlue is easily recognizable by its blue nozzle and blue fill cap, which helps to prevent this.

It’s critical not to start your engine if you unintentionally add AdBlue to your gasoline tank. In the worst-case situation, this could result in your vehicle being written off. Before you can replenish your fuel tank, you’ll need to drain it and carefully dispose of the contents. The best thing you can do is call your local garage or your breakdown company.

Running out of AdBlue – If you run out of AdBlue, your engine will not be damaged; most engines will automatically reduce engine performance when AdBlue supplies are depleted. Some vehicles may even be configured to wait till there is AdBlue in the tank before starting the engine.

Most new vehicles will come equipped with a driver information system that will alert you if you’re low on AdBlue. Although the absence of AdBlue will not hurt your vehicle directly. It’s important to remember, though, that not utilizing AdBlue in a car with an SCR system is illegal.

Contamination of AdBlue – Dust, dirt, oil, grease, and other contaminants can easily contaminate AdBlue. When refueling your vehicle from an AdBlue tank, it’s critical to make sure the fuel is pure. As a result, if you spill AdBlue, you won’t be able to use it again.

Where can I purchase AdBlue?

Although AdBlue is generally available at our Service Station Sites, it is important double-checking that they have it in stock before making a special trip. Our Evanton Skiach Service Station also sells AdBlue right at the pump.

AdBlue can be picked up in 5L, 10L, and 20L containers from certain of our depots.

Selected depots can also provide 205L Drums and 1,000L IBCs for commercial and agricultural applications.

How do I know when AdBlue tank is full?

Simply pour the solution into the car and drive until it’s full. Most AdBlue-equipped vehicles will have a gauge buried someplace in the car’s infotainment system that shows how full the tank is. You’ll know how much AdBlue you need if you keep looking until you discover it.

Is AdBlue flammable?

AdBlue isn’t a fuel or a fuel additive; it’s an exhaust fluid that has its own tank and is kept separate from the fuel in your vehicle.

In a nutshell, AdBlue is urea in liquid form. 67.5 percent ionized water and 32.5 percent urea make up the formula. The AdBlue fluid heats up as the engine heats up, releasing ammonia, which serves as a catalyst. Ammonia triggers a chemical reaction that converts nitrogen oxide to water and nitrogen, both of which are entirely safe. These are subsequently ejected as exhaust gases, reducing the environmental damage caused by diesel automobiles.

The AdBlue fluid should be topped up when your vehicle is maintained, but you will most likely need to top it up yourself once or twice between services to meet emission regulations. The location of the AdBlue fluid is normally indicated by a blue filler cap; however, always consult your vehicle’s manual first, as earlier diesel vehicles may not require AdBlue.

AdBlue is a colorless liquid created from a combination of high-purity urea (32.5%) and deionized water (67.5 percent ). The solution is a critical component of selective catalytic reduction (SCR) technology, which is one of the most successful systems for lowering nitrogen oxide levels in diesel engine exhaust gases.

Because nitrogen oxide combines with other gases in the atmosphere to generate microscopic particles and ozone, both of which can destroy delicate lung tissue in humans and animals, it is one of the most hazardous pollutants emitted by engines.

AdBlue fluid is pumped into the selective catalytic reduction catalyst when the engine burns the gasoline, converting the nitrogen oxide into a less damaging mixture of nitrogen and water vapour. The solution is kept separate from the diesel in its own tank before being fed to the exhaust gas using a dosing control system that provides enough AdBlue to account for 2–6% of overall fuel consumption.

When the urea in the SCR catalytic converter is heated, it turns into ammonia, which reacts with the nitrogen oxide in the emissions to transform the pollutants into nitrogen, water, and a small amount of carbon dioxide —all of which are already present in the air we breathe.

What is AdBlue used for?

Diesel engines emit a variety of toxic air pollutants that can cause breathing and respiratory difficulties in persons who are already vulnerable. The two most hazardous emissions linked with diesel automobiles are nitrogen oxide and nitrogen dioxide, which lead to smog and acid rain. AdBlue has been designed to work in conjunction with SCR technology. SCR is a technology that employs AdBlue to eliminate the most harmful oxides from diesel exhaust emissions.

AdBlue is one of the most effective methods for reducing nitrogen oxide levels in fuel emissions, and it will play a critical part in the future of diesel vehicles. The motoring industry has been taking steps to address the difficulties surrounding diesel emissions for some time, and AdBlue is gradually being heaped up on petrol station forecourts.

What emission regulation does AdBlue follow?

The Euro 6 regulation is the most recent European emission standard for cars and light commercial vehicles, requiring diesel cars to produce 0.08 grams of nitrogen oxide per kilometer and petrol vehicles to emit 0.06 grams per kilometer.

It’s critical to be familiar with AdBlue since every time you burn a fuel, fumes are produced, and AdBlue is utilized to remove them. All car manufacturers in the EU/EEA must test their vehicles to guarantee that they satisfy these permissible emission levels. The usage of an SCR system in conjunction with AdBlue is the preferred test method.

What is the Euro 6 regulation?

In September 2014, the Euro 6 regulation was initially introduced, and in September 2015, it became mandatory for all new cars. AdBlue fluid is the sole solution to meet Euro 6 emission rules for most diesel cars with 1.6 liters or more. Diesel vehicles now come standard with an AdBlue tank, as it is a legal requirement that all diesel emissions satisfy Euro 6 standards. You may have noticed a smaller blue or black cap next to the main fuel cap; this is for AdBlue.

Since December 2013, heavy-duty vehicles, such as trucks and buses, have been subject to the Euro 6 legislation. Larger vehicles, like as buses and trucks, are allowed a higher nitrogen oxide production than cars and light commercial vehicles, despite the fact that there are various categories for different sizes.

Which vehicles use AdBlue Fluid?

Since the mid-2000s, AdBlue has been utilized in agricultural vehicles, lorries, buses, and coaches that use selective catalytic reduction (SCR) technology.

The simplest way to see if you need AdBlue is to look under your gasoline cap cover; if there is a secondary, smaller black or blue cap adjacent to your main fuel cap, you will need it. To avoid confusion, the secondary cap is frequently labeled with the product name. Your owner’s handbook should also explain whether or not your car has an SCR system and how to properly maintain it.

If your AdBlue levels are low, most new vehicles feature a driver information system that will alert you if there is an error or if you are running low on lubricants or fluids, including AdBlue, and will remind you to refill soon.

AdBlue for Agriculture

Agricultural tractors and machinery were subject to EU Regulation 2000/25/EC, which established a succession of ever more restrictive limits for the emissions of hazardous pollutants from new tractors’ exhausts.

In 2005, two new standards, Stage III and IV, were adopted, introducing even more stringent limitations. Stage III was phased in between 2006 and 2013, while Stage IV went into effect in 2014 and is remains the law for newly built automobiles today. A Stage V standard has also been established, with intentions to implement it starting in 2019.

This new standard replaced the old ones and added new lower limits for agricultural vehicles to the non-road mobile machinery requirements. Manufacturers of agricultural machinery must utilize SCR technology, as well as Exhaust Gas Recirculation (EGR) and Diesel Particulate Filters (DPF), to assist reduce nitrogen oxide and particulate matter (PM) levels in emissions.

What is the shelf-life of AdBlue fluid?

AdBlue can be stored for up to 18 months. To keep AdBlue in top shape, place it in the following locations:

The shelf life is only about six months if you store it at a higher temperature or in a ventilated container.

Is AdBlue flammable?

AdBlue isn’t combustible and isn’t classified as a dangerous liquid. It’s a urea solution that’s based on water and presents little risk to humans. If you have sensitive skin, it’s a good idea to use gloves when handling the liquid to avoid irritation. However, avoid ingesting AdBlue or getting it in your eyes.

Can Adblue Freeze?

AdBlue does freeze, but only at -11°C, and it won’t start to freeze until it reaches -10°C. You should have no difficulty using the AdBlue tank because it is located near to the exhaust on most vehicles. The AdBlue tank is frequently heated with circulated engine coolant in vehicles where it is located elsewhere. Even if it does freeze, AdBlue will resume normal operation after it has thawed.

How can I estimate how much AdBlue I need for my fleet?

When estimating the amount of AdBlue you’ll need for a fleet of vehicles, consider the following factors:

When it’s time to replenish your AdBlue, the quantity you’ll need will be determined by the vehicle you’re driving. To accommodate the bigger volumes of the solution that will be employed, massive trucks and coaches will have far more capacity than passenger cars.

If you have an empty tank, most vehicles require a minimum amount of AdBlue to be replaced before the engine will operate again.

Where can I find an AdBlue supplier?

If you own or work for a firm with a big fleet of cars, it’s worth looking into obtaining AdBlue in greater quantities, such as in an IBC or in bulk, especially if your trucks travel long distances carrying significant cargoes. You’ll save more money if you buy your AdBlue fluid in advance rather than paying for refills as they’re needed, which will be more expensive.
