Product Description
1.Product introductionSCR Catalytic 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 290to400 ºC.   Almost no NH3 oxidation reaction  occur. Domestic former SCR catalyst entirely dependent on imports. Our research and development production SCR catalytic muffler successfully assembled Beijing Public Transport Corporation CO,LTD. Instead of its original import SCR catalyst product and fill in the blank of domestic production.

2.SCR system main include:  
urea solution , transporting devices, metering devices, injection devices, catalytic converters, exhaust temperature sensor and so on .catalytic converter is the core of SCR system .

3.SCR catalytic muffler features:
  Emission standard: Euro V      
  conversion rate : 98.5%
  Applicable models : the use of diesel vehicles
  Ignition temperature : 50 ºC      
  heat resistance : 800 ºC
  Part Number : BHLJ-CC-SCR
  Basic conversion when using urea : 4NO + 2 (NH2) 2CO + O2 → 4N2 + 4H20 + 2CO2
  Reaction temperature : <220 ºC  
  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

4.The results showed
diesel engine using SCR technology than using EGR plus particulate trap technology can save about 5% fuel consumption. Select SCR technology can achieve euro  standard and with high reliability, good stability, low fuel consumption , high power density, long oil change intervals ,low cooling requirements and other advantages. When upgrade euro V  standards , SCR technology is easier come true than EGR technology easier... Another SCR technology is not sensitive to ...sulfur content of the fuel .Therefore , SCR technology is one of  processing technology  which conform to China 's National Condition and can meet the euro  standard and emission requirements .
      In practical application, we often use Integrated SCR catalytic converter muffler which integrate.. SCR catalytic converter to diesel exhaust. Integrated SCR catalytic converter muffler is not only to catalytic reduction NOx, reduce exhaust noise of the engine but also compact structure , small size, easy to install.
