How much does AdBlue reduce NOx?

The use of AdBlue® can cut up to 90\% of harmful Nitrogen Oxide (NOx) emissions that a diesel car produces through its exhaust system following the combustion process. AdBlue® must be used in most diesel vehicles (cars, vans, trucks and buses), bought after October 2006.

What emission does AdBlue reduce?

In an SCR system, Diesel Engine Fluid (aka DEF or AdBlue® – a mixture of purified water and urea) is injected into the SCR catalyst. The fluid reacts with the harmful NOx emissions to create nitrogen, water and carbon dioxide – reducing emissions by up to 95\%.

How do you reduce NOx in diesel fuel?

Diesel engines operate at a higher temperature and pressure than petrol engines. These conditions favour the production of NOx gases. The quantity depends on the volume and duration of the hottest part of the flame. Q.

Is California banning def?

California will ban sales of new gas and diesel vehicles by 2035. In an executive order, Gov. Gavin Newsom said passenger vehicles will be required to have zero emissions. Gavin Newsom said passenger vehicles will be required to have zero emissions.

Why is AdBlue called AdBlue?

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.

Does AdBlue reduce pollution?

The SCR uses the diesel exhaust fluid or AdBlue to reduce harmful NOx emissions. When AdBlue meets a hot exhaust gas, the urea is converted into ammonia and carbon dioxide. When the ammonia encounters the catalytic elements inside the SCR core, it reacts with the NOx in the exhaust stream.

What does AdBlue do to diesel?

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.

How does AdBlue work chemistry?

Essentially, the SCR blends the AdBlue with the engine’s exhaust gasses, which creates a chemical reaction, to convert nitrogen oxides (NOx) into nitrogen, water and carbon dioxide (CO2). As a result, the gasses emitted are less harmful to the environment and our health.

What is NOx emission?

Nitrogen Oxides are a family of poisonous, highly reactive gases. These gases form when fuel is burned at high temperatures. NOx pollution is emitted by automobiles, trucks and various non-road vehicles (e.g., construction equipment, boats, etc.)

Do diesel trucks get smogged?

Diesel Smog Check – Since 2010 California has required all diesel trucks and diesel passenger cars which are 1998 model year or newer, and weight 14,000 GVWR or under, undergo a biennial smog inspection similar to their gasoline counterparts.
