What Is DEF

About DEF Solution

DEF (Diesel Exhaust Fluid) is, at a chemical Level, a combination of deionized water and urea that transform harmful nitrous oxide emissions into harmless water and gas. DEF is the registered trademark of VDA for AUS32, or Aqueous Urea Solution 32.5%

SCR engines use a diesel exhaust fluid (DEF) such as DEF. The fluid is stored in a separate tank in the system and injected into the exhaust stream. This injection causes a chemical reaction in the SCR catalytic converter which turns oxides of nitrogen (NOx) into environmentally friendly components, diatomic nitrogen (N2) and water. As a result, selective catalytic reduction systems are being used as a sustainable and effective way of protecting the environment.

Know More About-DEF

Reduce Disel Engine NOx Emission

All modern diesel engines with selective catalytic reduction (SCR) units in their exhaust systems can benefit from DEF. These include diesel-powered vehicles such as trucks, buses, tractors, cars, vans and off-road vehicles.
DEF will help your business to reduce harmful emissions and it will reduce your fuel costs by up to seven percent. The product can be stored for 18 months. It can be used in most weather conditions.
It is not a fuel, nor a fuel additive and needs to be used in a dedicated tank in your heavy-duty vehicle. It is replenished in a similar way to refuelling diesel. Should you spill DEF on your hands, simply wash it off with water.

1.How much DEF do I need?

Average consumption of DEF is generally 3 ~ 5% of diesel use, so you will need to tank much less for DEF then you do for diesel. You will use about 3~5 litres of DEF to every 100 litters of diesel.

2.How should I store DEF?

DEF can be stored for 1 year if this is done in a correct manner i.e. away from direct sunlight. It needs to be protected from too warm or too cold temperatures. Its freezing point is at -11 degrees Celsius. When it thaws, the product will retain its initial quality. It should be stored in a sealed package and in a well-ventilated storage area.

3.Why should I choose SCR with DEF over other technologies?

DEF combined with SCR offers you a fuel-efficient solution, with lower CO2 emissions then competitive solutions. All major European and North American truck manufacturers currently offer SCR equipped models. The future BS VI emission standard is set to reinforce the demand for this technology in India.

4.Why does DEF quality matter?

Various actions can affect the quality of DEF. To prevent contamination, it is imperative that foreign matters do not come into contact with the solution. Using contaminated DEF can lead to expensive catalyst replacement costs. Buying DEF from PowerBlue is a guarantee of the correct specification required for use with your SCR technology.

SCR Technology

SCR stands for an after-treatment technology called Selective Catalytic Reduction. This technology requires the use of a reagent called AUS 32 (also known as DEF in North America or ARLA 32 in Brazil) to reduce the NOx. Almost all major heavy-duty vehicles manufacturers have decided to use this technology to meet the new emission legislation on NOx emissions. Competitive technologies offer a less beneficial fuel efficiency and higher CO2 emissions. So, SCR is the most cost-effective solution to meet NOx emission standards.
The main components of the SCR system are the SCR catalyst, the DEF injection unit, the DEF tank and the DEF dosing control unit. DEF is injected into the exhaust pipe, in front of the SCR catalyst, downstream of the engine. Heated in the exhaust it decomposes into ammonia and CO2. When the NOx reacts inside the catalyst with the ammonia, the harmful NOx molecules in the exhaust are converted to harmless nitrogen and water.

For the correct functioning of your SCR system, make sure you use only high quality DEF such as PowerBlue. Poor quality reagent that is contaminated with foreign matters risks damaging your catalyst.

There are different emission standards around the world, setting specific NOx emission limits that require the use of SCR and DEF. The four main pollutants covered by vehicle emission legislation are Oxides of Nitrogen (NOx), Particulate Matter (PM), Carbon monoxide (CO), and Hydrocarbons (HC).
