What is a Particulate Filter?

[GenesisRose]

A particulate filter is a ceramic filter installed in the diesel engine emission system, which captures particulate emissions before they enter the atmosphere. Functions of the Particulate Filter: The particulate filter can reduce soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Application Technology of the Particulate Filter: The particulate filter employs advanced electronic control systems, catalytic coatings, and fuel-additive catalysts. Principle of the Particulate Filter: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate trap through a dedicated pipeline. After passing through its densely arranged bag-type filter, the carbon particles are adsorbed on the filter made of metal fiber felt. When the adsorption of particles reaches a certain level, the burner at the end automatically ignites and burns, turning the adsorbed carbon particles into harmless carbon dioxide that is then released.
