SCR Catalytic Converter Muffler for Diesel Vehicle Diesel Engine

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 ºC.  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 converterMuffler is the core of SCR system .
 
Features:
Emission standard: Euro III , Euro IV ,Euro V   
conversion rate : 98.5%
Applicable models : for diesel vehicles
Ignition temperature : 50 ºC

Basic conversion when using urea : 4NO + 2 (NH2) 2CO + O2 →4N2 + 4H2O + 2CO2
Reaction temperature : <220ºC
ESC cycle NOx reduction efficiency of>90%                   
ETC cycle NOx reduction efficiency of > 80%
The average concentrations of NH3 overflow <5ppm
Transient overflow concentration <10ppm
The average concentrations of NH3 overflow <5ppm   
transient overflow concentration <10ppm

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.
