DPF is the only option to satisfy particle number emissions. Common DPF support materials are ceramics, aluminum titanate and silicon carbide. The choice of carrier material is mainly based on the use of DPF and regeneration strategy, including carbon back pressure, filtration efficiency, regeneration temperature, time and so on. Our DPF coating technologies are based on a high thermal stable wash coat formulation with excellent NO2 formation.
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. It also converts NO into NO2 for passive regeneration of downstream catalyst particle trap (CDPF) and improves NOx conversion efficiency of SCR.
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.
Reactions in CDPF: The NO produced by the reaction of NO2 with carbon particles is oxidized to NO2 again, then continues to react with carbon particles for continuous utilization.
