One of the essential parts of the SCR (Selective Catalytic Reduction) after-treatment system designed to minimise NOx from the exhaust is DEF (Diesel Exhaust Fluid), a non-toxic mixture of 67.5% water and 32.5% automotive grade urea. To guarantee that the DEF is free of impurities, SCR systems are installed with one.
For the vehicle to stay in working order, diesel exhaust fluid (DEF) is necessary. Before the exhaust leaves the tailpipe, a solution of water and urea is injected, igniting a chemical reaction that converts dangerous pollutants into clean air.
The Global Diesel Exhaust Fluid filter market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
New WABCO Diesel Exhaust Fluid is being launched by ZF, and it is crucial for the hassle-free and efficient functioning of Selective Catalytic Reduction (SCR) after-treatment systems used to satisfy BS-VI regulations. SCR technology employs a catalytic device to convert harmful NOx emissions from diesel engines into water and nitrogen.
An ongoing supply of ammonia gas is necessary for the chemical processes carried out in SCR systems. SCR uses a urea solution known as Diesel Exhaust Fluid to supply ammonia in automotive applications (DEF).This is fed into the diesel exhaust stream, and a catalyst, combined with heat from the exhaust and the fluid, transforms the NOx into innocuous gases.
A 32.5% solution of pure urea of automotive grade in deionized water is used to make diesel exhaust fluid. To reduce the concentration of NOx in exhaust emissions from diesel engines, DEF is used in commercial vehicles equipped with selective catalytic reduction after-treatment equipment.
