DOC is one of the most important catalysts for diesel engine reprocessing. Its main function is to oxidize the unburned hydrocarbons (HC) in the engine and the carbon monoxide (CO) produced during combustion into harmless water and carbon dioxide. At the same time, it can also convert NO into NO2 for passive regeneration of downstream catalyst particle trap (CDPF) and improve NOx conversion efficiency of SCR. Depending on the emission requirements, it is sometimes necessary to integrate multiple functions on DOC, which also brings great challenges to the design of DOC. We can provide the following conventional DOC products, but also according to the customer's engine emissions input to provide customized DOC products.
Doc: Oxidation of No to No2 and removal of CO and HC.
CDPF: the captured carbon particles react with NO2 at low temperature to produce CO2 emissions.
DOC WORKING
The DOC system adopts an injection system with compressed air assistance. The urea solution supply pump is equipped with a built-in control device, which can control the internal urea solution supply pump and compressed air solenoid valve to operate according to established procedures.
1.Excellent thermal shock resistance. 2.Unique cellular designs make metal liquid reducing the vortex and raducing the bubbles in the casing; 3.Accurate extrusion die make product quality extremely stable and consistency; 4.Obvious filter effect; 5.Improving the casting surface performance and improving the density of the casting; 6.Improving metal structure and quality prolong the working life of the casting; 7.Good chemical stability,not affected by of melted metal,no change in its chemical compound; 8.Precise dimension and can be used in pruduction line automatic filter mounting
