Does Volvo Have a Particulate Filter?
1 Answers
Volvo vehicles are equipped with particulate filters to meet the China VI emission standards. A particulate filter is a ceramic filter installed in the diesel engine's exhaust system, designed to capture particulate emissions before they enter the atmosphere. It can reduce soot emissions from diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. Diesel engine pollution primarily comes from three sources—particulate matter, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Particulate matter (soot) mainly consists of tiny carbon or carbide particles (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 pipe. Inside, a densely arranged bag-type filter captures the soot particles on a metal fiber felt filter. When the accumulated soot reaches a certain level, the burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide. To check if a Volvo vehicle has a particulate filter, you can use the following three methods: 1. Refer to the Owner's Maintenance Manual and Owner's User Manual to see if the particulate filter function is mentioned. Additionally, carefully review the fault codes in the manual to check for a "Particulate Filter" warning light indicator. 2. Check the label on the oil filler cap. If it explicitly states 0W-20 grade oil, it indicates the presence of a particulate filter. 3. Inspect the exhaust pipe behind the catalytic converter for an additional cylindrical section. If present, that is the particulate filter.
