Does the Volkswagen Bora Have a Particulate Filter?
1 Answers
The Volkswagen Bora is equipped with a particulate filter to meet the China VI emission standards. The particulate filter is a ceramic filter installed in the diesel engine's exhaust system, which captures particulate emissions before they enter the atmosphere. It can reduce soot emissions from diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Diesel engine pollution mainly comes from three sources—particulate emissions, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Among these, particulate emissions (soot) are mostly composed of tiny particles of carbon or carbide (smaller than 4-20μm). How the particulate filter works: 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 filter through a dedicated pipeline. After passing through the densely arranged bag-type filters inside, the carbon soot particles are adsorbed onto a filter made of metal fiber felt. When the adsorption of particles reaches a certain level, the burner at the end automatically ignites, burning off the adsorbed carbon soot particles and converting them into harmless carbon dioxide that is then released. To check whether the Volkswagen Bora has a particulate filter, you can use the following three methods: Check the and to see if the particulate filter function is mentioned. Check the label above the oil filler cap. If the oil cap clearly indicates 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Look at the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section. If so, that is the particulate filter.
