(DOC) Diesel Oxidation Catalyst
   



with increasing appearance of diesel engine automobile, the particulate
from emission, mainly carbon, enhances the pollution to the enviroment. The US enviromental office promulgated the particulate.regulation for diesel engine, stipulating the particulate in diesel passenger car's emission should meet the criterion :below2.0g/mile. The diesel particulate filter is able to filter above 80% carbon smoke particulate,it would be a great help to solve the problem of air pollution in city.
  Basic working principle :If the DPF is coated with noble metal (such as
Pt, Pd and Rh), black smoke with carbon particulate from diesel engine ,pass through a special tube and enter the filter. The carbon smoke particulate is absorbed to the filter made of metallic fibre felt, when passing the inner dense set and bag-style filter. when particulate absorption reaches some degree, the tail burner would be ignited to burning automatically. In this case, the particulate absorbed is burned out and turned into nontoxic co 2 then discharge. The full device is designed as double room structure, and filtration and recycle are going in different areas, making them non-disturbed. The system can work automatically whatever working condition the engine in. The special filter made by honeycomb ceramic,ceramic particulate filter, acts as capturing device, can capture the carbon particle which diameter is less than 30 micron.
 JXYY  Diesel Oxidation Catalysts are specifically developed for various diesel engine emission control covered from on-road vehicles application to off-road construction or mining application. Our high efficiency and performance stability DOC products have been recognized in many applications.

Current product offer covers from 0.1 liters to 25 liters as a single DOC which would be perfect solution for diesel engine displacement from 0.5 to 25 liters.
