A German inventor named Rudolf Christian Karl Diesel or Rudolf Diesel was the one who discovered and invented diesel in the 1890s. Over time, it became so prominent that its realm extends to almost all industries, to the point that it can be daily observed if you were to look under the hood of automobiles.
Diesel has been used for many engines of every mode of transport such as rail, sea, air, and road. It is also commonly used as mechanical engines, mobile drives, and power generators. Also, it is used for running plants, farms, and construction equipment.
Today, it is undeniable that many people are now driving diesel-powered vehicles. Diesel technology has advanced significantly and quickly that there are now vehicles, especially luxury sports cars with high top-end speed. Not to mention, there are various advantages of diesel fuel over gasoline that cannot match.
Diesel fuel has made some notable contributions to the advancement of the world. However, as more and more people realize its use and potential, it increased large sums of particulate matter or black smoke. It is known that diesel fuel produces many harmful emissions, causing pollution and damaging the environment.
To address the matter, there have been various attempts to reduce the emission of pollutants. Selective Catalytic Reduction or SCR is one of the successful solutions. Together with diesel exhaust fluid (DEF), it helped change the fuel’s image and made diesel viable for the future. So, how exactly does SCR work, and what role does DEF play in making that happen?
SCR uses ammonia to break down dangerous nitrogen oxides emissions produced by diesel engines into nitrogen and water. SCR delivers ammonia through a UREA solution or DEF in automotive applications, sprayed into the exhaust system by an advanced injection system, and converted into ammonia on a particular catalyst.
While the SCR is not a new technology as it has been around for half a century, it may still be new for many. As such, many false beliefs are surrounding the system.
