How Does Urea Work In Diesel Engines? Here’s everything you need to know:
How Does Urea Work In Diesel Engines?
Urea SCR cleans the exhaust after combustion. … The heat breaks the urea down into ammonia—the actual NOx-reducing agent. Through a catalytic converter, the ammonia breaks the NOx down to harmless nitrogen (N) gas and water vapor. The exhaust is no longer a pollutant; the atmosphere is about 80% nitrogen gas.
What Is Urea Additive For Diesels? AdBlue is the trade name for a type of diesel exhaust fluid. It’s a mixture of urea and deionised water that’s stored in a separate tank from the car’s fuel. When the car’s engine is running, tiny amounts of AdBlue are squirted onto the exhaust gas produced, turning the NOx into nitrogen and water.
Can You Pee In Your Def 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.
Why Is Urea Used In Def? The Urea and water in DEF, when mixed, will freeze at the same rate. This is beneficial to the user because when the fluid thaws the DEF solution does not become diluted or overly concentrated. Freezing and thawing cycles has no impact on the grade of the product. DEF expands when frozen as much as 6.5% – 7% by volume.

How Often Do You Put Def In A Diesel?
For example, for every 100 gallons of diesel fuel consumed, between 2 and 4 gallons of DEF will be automatically injected into the exhaust system. The typical DEF tank will be approximately 15 – 20 gallons, thus requiring a fill every 5,000 to 6,000 miles.
Can I Put Adblue In My Diesel Tank?
AdBlue is commonly mistaken as a fuel additive when it is actually an exhaust fluid that should never be mixed with diesel. … Adding AdBlue into your diesel fuel tank can cause thousands of pounds worth of damage.
Can You Use Water Instead Of Adblue?
Using water instead of AdBlue – In short, you mustn’t use water instead of AdBlue, or water down the AdBlue in anyway. AdBlue is a mixture of urea and 67.5% de-ionized water. Where as tap water contains a lot of minerals and ions that is harmful to the vehicle exhaust treatment system.
Is Urine In Def?
Diesel exhaust fluid is not made of urine, and if you are going to urinate in your SCR system, you’re looking at having to pay some pretty hefty repair costs to clean and replace engine components once they have been contaminated.
Is Def Fluid Made From Pig Urine?
But despite DEF earning the nickname “pig urine,” Diesel Exhaust Fluid is actually made of commercial-grade urea—synthetic ammonia and carbon. So, to simplify things: the urea and water in DEF heat up, producing ammonia. This ammonia then breaks down and neutralizes the NOx gases.
What Can I Use Instead Of Def?
DEF is urea or otherwise known as aqueous ammonia. Windshield washer fluid that contains ammonia will do in a pinch.
What Year Did Dodge Start Using Def?
This lead to the introduction of the SCR (Selective Catalyst Reduction) and DEF (Diesel Exhaust Fluid) in most heavy duty diesel pick-ups by 2013. Some manufacturers, such as General Motors, introduced the system a little earlier, with the Duramax getting it in 2011.
What Fluids Will Destroy A Diesel Engine?
Thousands of diesel engines fail prematurely each year aided by the presences of glycol, fuel, soot and water in the engine oil.
Is There Any Difference In Def Fluids?
The main component that sets brands of DEF apart from each other is the level of purity in the product. DEF fluids all must meet an international standard and standards from the EPA that measure the purity of this fluid. … However, if they don’t also meet the ISO 22241 standard, they are not DEF.
What Happens If You Accidentally Put Def In Diesel Tank?
What Happens When You Put DEF in Your Fuel Tank? If you pour DEF into your fuel tank and realize your mistake immediately, your fuel system needs to be flushed, and there may be some part repairs or replacements required just from the fluid having been there.
Do All Diesel Engines Require Def?
A: Because almost all diesel-powered passenger cars and trucks built since 2010 are equipped with Selective Catalytic Reduction (SCR) and require Diesel Exhaust Fluid (DEF), it is readily available at most fueling stations and automotive parts retail stores. Truck stops often have a DEF pump right on the fuel island.
How Many Miles Will 1 Gallon Of Def Last?
How much DEF is used per kilometer? This means that with a fuel consumption of 6 miles per gallon and a rate of 3%, your truck will consume approximately 1 gallon of DEF per 200 miles.
What Happens If I Don’t Put Adblue In My Diesel Tank?
What happens if I run out of AdBlue? If you run out of AdBlue while you’re driving, then the engine’s power and performance will be reduced to limit its emissions. Once you’ve stopped, you won’t be able to restart the engine if the AdBlue tank’s empty.
What Happens If You Put A Small Amount Of Adblue In Diesel Tank?
A single drop of Diesel can contaminate several litres of AdBlue®. If you start up with an AdBlue® tank filled with Diesel, you risk causing very serious damage to your vehicle’s SCR system. If you do start up, you vehicle will begin to behave strangely.
What Does Adblue Do To Diesel Engines?
AdBlue is a non-toxic diesel exhaust fluid, made up of high purity urea and deionized water used to treat exhausts on diesel engines to reduce harmful emissions. Although it’s odorless and non-toxic, it can corrode metallic surfaces.
Can I Make My Own Adblue?
It can only be produced industrially. Making AdBlue® yourself may have adverse repercussions on your vehicle. the first involves dissolving granules of solid urea, called prills in demineralised water; the second involves mixing synthetic urea with demineralised water.
Can I Refill Adblue Myself?
Yes, you can top up with AdBlue® yourself. Every TotalEnergies service station sells standard 5L and 10L cans of AdBlue®. TotalEnergies is also gradually deploying special pumps for light vehicles. Never top up with a pump for heavy goods vehicles.

Can You Drive A Diesel Without Def?
SCR Systems. . Modern trucks will not run without the DEF. Hence the need for diesel truck owners to check their fluid levels frequently. Reducing emissions should be everyone’s goal. Maintaining your vehicle would also reduce emissions and DEF consumption.
