Does Volkswagen have a particulate filter?
2 Answers
Volkswagen has a particulate filter. Function 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 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 exhaust particulate trap through a dedicated pipe. After passing through the densely arranged bag-type filters inside, the carbon particles are adsorbed onto 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.
Last time I took my Volkswagen Tayron for maintenance, the technician mentioned it's equipped with a particulate filter. This device specifically traps soot particles in the exhaust, and now most Volkswagen models meeting China VI standards have it installed. But I must remind you, if you frequently drive short distances, the emission warning light might illuminate on the dashboard—that indicates clogged particulates. When I encountered this last time, the technician advised me to drive in Sport mode for half an hour on the highway to burn off the carbon deposits using the high exhaust temperatures. Now the car's condition has improved significantly, and fuel consumption has returned to normal levels.
