What is the use of urea in trucks?

What is the use of urea in trucks?

Vehicles with SCR technology make use of a special additive called Adblue, which is essentially a 32.5 per cent solution of urea in de-ionized water. It is a non-toxic liquid and does not damage the environment.

Why is urea used in def?

DEF is most commonly manufactured in a prill, or granular form. The higher grade, “environmental” urea used to make DEF has had all contaminants removed to maintain the cleanliness and integrity of a diesel engine’s SCR system, which is designed to be highly sensitive to any and all contamination.

What does urea injection do?

Urea injection into the exhaust systems of diesel engines is a newly developed method of pollution reduction. The pollutants removed by these systems are nitrous oxide and carbon monoxide. …

Is urea and AdBlue the same?

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.

What is urea in diesel engines?

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 you use water instead of DEF?

If you remove the urea from the DEF — that is, if you run water through the injectors instead — it probably won’t hurt anything, since you’re reducing the level and quantity of corrosive reactants inside the stainless steel SCR system.

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.

Can I use pee instead of AdBlue?

Using pigs’ urine (or any urine) instead of AdBlue® would cause irreversible damage to the SCR system in your vehicles.

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 use water instead of DEF?

Subject: RE: Anyone replace DEF with water? Water won’t hurt the system but it will de-rate you pretty quick. ECM compares NOx values pre/post, if conversion is low it will start throwing codes and will eventually derate.

How does urea work in diesel engines?

The value of using urea in diesel powered vehicles exhaust systems stems from the chemical’s ability to convert the majority of the NOx component in the gases to harmless nitrogen and water. This use of urea in diesel vehicles is typically achieved by injecting a fine spray of urea into the exhaust catalyst,…

What is the best brand of diesel exhaust fluid?

If you want the best diesel exhaust fluid, we highly recommend the BlueDEF DEF002. This brand gives you the cleanest emissiosn and works the most effectively according to our surveys and research. It is very clean and reliable and meets all of the ISO purity and composition standards. Also, it helps increase gas mileage as a nice bonus.

Is diesel exhaust fluid hazardous?

Diesel Exhaust Fluid (DEF) is not toxic, harmful or dangerous. In fact, of all the fluids used in a truck, such as diesel, engine oil, brake fluid, antifreeze and windscreen wash, DEF is the least hazardous.

How long does DEF Diesel Exhaust Fluid last?

How long does Diesel Exhaust Fluid (DEF) last? Diesel Exhaust Fluid (DEF) can last for up to two years if properly stored. Shelf life can be drastically reduced if DEF is exposed to direct sunlight or if the temperature of the fluid rises above 86 degrees Fahrenheit for long periods of time.
