The specifications of the carrierφ266*80, SCR exhaust pueifier mainly applied to the diesel engine exhaust system. The selective catalytic reduction, the principle of it is under the action of catalyst, The principle of SCR is selective catalytic reduction, it is under the effect of catalyst, reducing agent NH3 under 290-400 will be NO and NO2 reduction into N2, and almost NO NH3 oxidation reaction.

    SCR system mainly includes: urea aqueous solution tank conveyer metering device spray temperature and exhaust gas sensors, catalysts and their catalytic (agent) is the core SCR system.

The results showed that the diesel engine using SCR technology than using EGR and particulate trap technology about a 5% lower fuel consumption. Choose the SCR technical route to realize the standard with high reliability stability good fuel consumption low power density and high oil change cycle is long low cooling requirements, and upgrade for the domestic V standard, SCR technology is easier to implement than an EGR technology, also is not sensitive to fuel sulfur content of the SCR technology.

Commonly used in practical application of the SCR catalytic converter and diesel engine exhaust muffler integration together of integrated SCR catalytic conversion of muffler. Integrated SCR catalytic .

conversion of muffler can not only catalytic reduction of NOx, reduce the exhaust noise of engine, and compact structure, small volume, easy to install.

Domestic original SCR catalysts are all dependent on imports, our company research and development production of SCR catalysts can be successful assembly major public transport companies in China, instead of the original SCR catalysts products to be imported, and fills the blank of production in domestic.

This product can be custom-made design production, can meet the euro III, IV, V requirements (also can meet the needs of the European standard)
