What is urea AdBlue?

What is urea AdBlue?

AdBlue is a liquid solution of urea (the stuff found in urine), and when it meets a hot exhaust system it releases ammonia which is a catalyst to a chemical reaction that converts dangerous Nitrogen Oxides into two harmless products – water vapour and Nitrogen.

Is urea the same as AdBlue?

AdBlue is actually a synthetic urea which works by turning nitrogen oxide into harmless steam and nitrogen. ... AdBlue is not injected into the engine as a fuel additive. It is added to the catalyst system in the car's exhaust system.

Does AdBlue contain urea?

AdBlue® is a synthetic, highly purified solution of urea and demineralized water NOT pigs urine. Whilst the chemical urea is in pigs' urine, it is found in much lower concentration alongside many other elements.

How is urea made for AdBlue?

Well, AdBlue urea is made by heating up synthetic ammonia and carbon dioxide. The urea is then added to the de-ionised water to create AdBlue. AdBlue sits in a separate tank to diesel and, unlike petrol or diesel, isn't injected into the engine. Instead, it's injected into the exhaust system.

Can I pee in DEF tank?

Please do not urinate in your DEF tank, the SCR system will be damaged and it will cost thousands of dollars to repair.

What does urea do to diesel exhaust?

Urea SCR cleans the exhaust after combustion. The urea solution is held in a separate storage tank and injected as a fine mist into the hot exhaust gases. The heat breaks the urea down into ammonia—the actual NOx-reducing agent.

Can I pee in AdBlue tank?

But sadly, the answer is "no". A modern clean diesel car will recognize that your pee is not the right stuff. AdBlue solution has a far higher concentration of urea--32.5%--mixed into deionized water.

How do you make urea?

The chemical compound urea is made by heating ammonium carbamide, a combination of ammonia and carbon dioxide, in a sealed container. The heat dehydrates the compound and forms urea, a crystal-type substance.

Is urea made in Australia?

For Australia and NZ, the majority of granular urea is currently imported, predominantly from the Middle East, South East Asia and China. Domestic production totals less than 0.5 Mt with production sites in Queensland, Australia and North Island, New Zealand.

What is AdBlue made of?

• AdBlue is a colourless liquid that is made from a mixture of high-purity urea (32.5%) and deionized water (67.5%).

Do all bluetecs use AdBlue?

• Yes, Blue tec engines use Ad Blue (but not all common rail engines are Bluetec) and it's about $6.00 per gallon (non factory brand diesel exhaust fluid) made for Mercedes truck engines that will work in Mercedes Bluetec cars. The cost in real life (for a car) comes out to about an additional two - one hundredths of a cent per mile.

Is AdBlue pig urine?

• AdBlue is a colourless, non-toxic mixture of urea and de-ionised water. It's not actually blue at all. Lots of people think AdBlue is made of pig urine - it's not . The urea used in AdBlue is a high purity man-made solution - pig urine wouldn't be pure or sterile enough for a commercial product.

What is AdBlue, SCR technology?

• AdBlue is used in cars running with diesel engine, where in catalyst SCR (Selective Catalytic Reduction) is implemented. SCR technology is implemented to reduce harmful gases in diesel engines and meet the EURO4, EURO5, EURO6 and EURO7 standards of emissions. These strict standards are required in many countries all over the World.
