Silicon Carbide DPF for Catalytic Converter Details:
With increasing appearance of diesel engine automobile, the particulate from emission, mainly carbon, enhances the pollution to the environment. Regulation for diesel engine, stipulating the particulate in diesel passenger cars emission should meet the criterion: Below 2.0g/mile. The diesel particulate filter is able to filter above 80% carbon smoke particulate. For practical application, it would be a great help to solve the problem of air pollution. If the DPF is coated with precious-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 fiber felt, when passing the inner dense set and bag-style filter. When particulate absorption reaches some degree, the tail burner would be ignited to burn automatically. In this case, the particulate absorbed been burned out and turned into nontoxic CO2 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. Especially made honeycomb ceramic particulate filter, acts as capturing device to the particulate to some extent. Diesel particulate filter is made of Sic, and it is used to remove black smoke (PM e. G.: Hydrocarbons, soot) from diesel engine exhaust. And usually DPF removes 95% or more of the soot. Working principle: By forcing the exhaust gases through the walls between the channels of the DPF, the particulate matter is deposited on the walls, so reducing the amount of air pollution.
