Diesel Particulate Filter
 
Our diesel particulate filter can meet the requirement of Euro IV and Euro V emission standards. and usually, DPF remove 90% even more of the diesel particulate matter and the soot, including ultra small particles. And the filtration efficiency can arrive to Euro V. In
 
 Working Principle
 
Inside the DPF, there is a honeycomb ceramic structure designed to filter the exhaust gases while minimising flow reduction. By forcing the exhaust gases through the walls between the channels of the DPF, the particulate matter (PM) is deposited into the channels, after the proper ways of regeneration to burn the PM and soots to get the clean air from the polluted exhaust gas
