SCR Catalyst and Doc Ceramic Catalyst for Bus or Commercial Vehicle Auto Part

SCR Catalytic Converter Muffler is mainly used in diesel engine exhaust system . SCR means selective catalytic reduction. Its principle is that NO and NO2 reduced to N2 under reducing agent NH3 and 290-400 Celsius.  Almost no NH3 oxidation reaction occur. Our patented SCR catalytic muffler successfully assembled Beijing Public Transport System in 2008 . We also supply Catalytic Converter, Catalytic muffler, Motorcycle catalytic converter, DOC Catalyst, Diesel Particulate Filters, DPF, SCR catalyst ,Ceramic honeycomb monolith , Metal honeycomb carrier, ect. Our  management system has been certified the ISO9001 and TS16949 by SGS company.
 
SCR system main include:  urea solution , transporting devices, metering devices, injection devices, catalytic converters, exhaust temperature sensor and so on . And our SCR catalytic converter Muffler is the core of SCR system .

The results showed that diesel engine using SCR technology than using EGR plus particulate trap technology can save about 5% fuel consumption. Select SCR technology can achieve Euro IV~Euro V standard and with high reliability, good stability, low fuel consumption , high power density, long oil change intervals ,low cooling requirements and so on.
 When upgrade to Euro V standards , SCR technology is easier applied in the market than EGR technology . In practical application, we often use completed SCR catalytic converter muffler which  not only to reduce NOx, but also reduce the noise from diesel engine.  
 
In addition ,our GXLJTM SCR catalyst can removes nitrogen oxides (NOx) from diesel vehicles. In the SCR process, the reducing agent reacts with NOx to convert the pollutants into nitrogen(N2), water (H2O) and tiny amounts of carbon dioxide (CO2) , which is then expelled through the vehicle tailpipe. Applications include medium and heavy-duty diesel trucks, all on road and non-road vehicle and various construction machinery vehicles.
We can supply all kinds of size according to customers' requirements to meet Euro III, Euro IV and Euro V.
