Passive Diesel Particulate Filter (DPF)  for Construction equipment

The main component of diesel engine exhaust gas purification catalyst (DOC+DPF catalyst ) , can be directly oxidized and decomposed in the diesel engine exhaust particulate matter (PM). Compared to the conventional platinum catalyst , since the NOx catalyst without passing through the DOC conversion NO2, thus reducing the amount of expensive platinum , lower cost , and can obtain the same decomposition performance at lower temperatures, and in temperature can be increased at the same rate of decomposition .
   
Using catalyst can also improve the combustion performance to the number of PM 's calculations , can reach more than 90% removal efficiency . In addition , the usage of the present catalyst can also be a diesel engine exhaust gas treatment apparatus to reduce the cost and energy efficiency .

In summary,the heat-resistant ceramic surface coated with the catalyst, the catalyst of the DPF arranged on the downstream of the DOC , the exhaust gas can be removed in the formation of PM in diesel engine exhaust gas treatment device .

[Basic principles]
The catalyst contains a metal oxide , an alkali metal sulfate , and quartz. The three dimensional structure of a separator made of a porous material having uniform adsorption state is maintained , through the membrane having an average pore size of 5 ~ 15um pore structure , thereby obtaining the exhaust gas having a high catalytic activity and heat resistance, and the collection efficiency purifying filter .
             
[Pollution control effect]
PM quantity calculation results show that the removal rate reached more than 90%.
Using engine bench test devices, measuring catalyst DPF on this measuring device ( vehicle exhaust particulates counter ) by particulate matter contained in exhaust gas downstream of the number of PM , the experimental results obtained indicate a high removal rate .
