4 maj 2022 · Dlatego we współczesnych silnikach Diesla spełniających normę emisji Euro 6 lub wyższe stosuje się niemal bez wyjątku system SCR (wyjątkiem tym są diesle Mazdy). SCR to skrót od selektywnej redukcji katalitycznej, a chodzi tu o redukcję tlenków azotu (NOx) .
12 wrz 2023 · Selective Catalytic Reduction (SCR) is a cutting-edge technology that has revolutionized the way diesel engines manage their emissions. By precisely injecting a urea-based solution into the exhaust stream, the SCR system can effectively convert harmful NOx and PM into harmless nitrogen gas and water vapor.
SSZ-13 is a high-silica, chabazite type zeolite that is commonly used in copper-exchanged diesel SCR catalysts (Cu/SSZ-13). SSZ-13 belongs to the ABC-6 family of zeolites. It has pore openings of ~3.8 Å, allowing free transport of all NH 3-SCR reactants and products.
From selective catalytic reduction (SCR) systems to diesel particulate filters (DPFs) and exhaust gas recirculation (EGR) systems, these technologies offer effective solutions for controlling nitrogen oxide (NOx), particulate matter (PM), and other pollutants.
10 sty 2024 · SCR systems in diesel engines represent a more active approach to emissions control compared to the passive catalytic converters found in gasoline vehicles. While catalytic converters act like a filter that traps harmful emissions, SCR systems actively inject Diesel Exhaust Fluid (DEF) into the exhaust, which chemically reacts with nitrogen ...
13 sie 2024 · Selective Catalytic Reduction is an advanced emissions control technology used in diesel engines to convert nitrogen oxides (NOx) into harmless nitrogen and water. SCR systems work by injecting a diesel exhaust fluid (DEF), usually a urea solution, into the exhaust stream where it reacts with a catalyst to break down NOx.
