Does the Volkswagen Passat Have a Particulate Filter?
1 Answers
Volkswagen Passat does not have a particulate filter. Function of the particulate filter: The particulate filter can reduce soot produced by diesel engines by over 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Application technology of the particulate filter: The particulate filter utilizes 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 engine exhaust particulate trap through a dedicated pipeline. It then passes through a densely arranged bag-type filter inside, which adsorbs the carbon soot particles onto a filter made of metal fiber felt. When the adsorption of particles reaches a certain level, the burner at the end automatically ignites and burns, converting the adsorbed carbon soot particles into harmless carbon dioxide that is then expelled.
