Urea sensor for SCR systems Car Engineer: Learn

Many passenger cars and commercial vehicles with diesel engines are already equipped with an SCR system. By making an aqueous urea solution (AdBlue or urea solution) react with nitrogen oxides in the engine exhaust, it chemically converts (reduces) nitrogen oxide to nitrogen (N 2) and water. The efficiency of this process depends on a precise metering of the amount of urea that is injected, which in turn necessitates a measurement of the urea A Review of NOx Reduction for Urea-SCR System and spray preparation, the SCR technology has been successfully introduced in the design passenger car market. In urea SCR, the chemical reactions take place at lower temperature of 200- 400C with the aid of a catalyst bed. Urea is injected in liquid form.

(with picture) The urea introduction takes place in the system's selective catalytic converter (SCR) section where a thin jet linked to a separate urea tank sprays a fine mist of the liquid into the NOx rich exhaust gas. The exhaust gas then released into the atmosphere is almost completely soot and NOx free.A Review of NOx Reduction for Urea-SCR System and spray preparation, the SCR technology has been successfully introduced in the design passenger car market.

High values of NO x reduction may be obtained with urea as a reducing agent and a standard SCR catalyst based on TiO 2-WO 3-V 2 O 5.The process was carefully investigated for possible secondary emissions and it could be shown that urea-SCR does not lead to relevant emissions of nitrogen dioxide, nitrous oxide, hydrogen cyanide and isocyanic acid.
