Study on the Integration Technology of After-Treatment System of the Diesel of Heavy-Duty Machinery

In order to be friendly to environment,the mechanical engineering meet new challenge. It should not only ensure high efficiency, low fuel consumption, but also ensure low emissions, which can achieve the purpose of green manufacturing. Under these conditions, the emission regulations are developed by different governments. Euro VI emission is developed by EU, in order to meet it, it will be necessary to apply the integration technology of after-treatment system for reducing of both PM and NOx. Different kinds of integration technology are described. The Ammonia slip catalysts (ASC) which must be used to reduce NH3 is also introduced.
