nh3 selective catalytic reduction in diesel engines

Selective Catalytic Reduction (SCR) The primary function of the SCR catalyst in a Diesel ATS is to convert harmful nitrogen oxides (NOx = NO + NO2) in the exhaust gas to nitrogen and water. The SCR reaction takes place at the catalyst surface in the presence of NH3 which is generated from AdBlue®/DEF (solution of 30% of Urea in water) upfront the SCR catalyst. Dinex has a variety of SCR catalyst technologies that can be selected...

...Diesel Engine With Cummins Brand Cummins designs, develops and supports every component from air handling to exhaust aftertreatment as a totally integrated system.

100CPSI Diesel Engine SCR Ceramic Substrate For Selective Catalytic Reduction 2. 1. Product use After coated with catalysts, this product is applied in catalytic converter of diesel vehicle to catalyze, convert and purify the exhaust, making vehicle ...

...Selective Catalytic Reducer for Diesel Vehicles Product Description 1. Introuduction The 32.5% urea aqueous solution is precisely atomized by a urea dosing system and injected into the exhaust pipeline, where it mixes with diesel engine exhaust gases. Through pyrolysis and hydrolysis reactions, the solution decomposes into ammonia (NH3...

..., non-irritating, and non-flammable. It is suitable for the SCR system of National IV, National V, and National VI emission engines and is the standard configuration of SCR technology. This product produces a selective catalytic reduction reaction with

..., particularly in vehicles equipped with Selective Catalytic Reduction (SCR) technology. This technology helps reduce nitrogen oxide (NOx) emissions from diesel engines. The urea pipe carries a solution of urea and water, commonly known as AdBlue, which...
