Which Cars Are Equipped with Particulate Filters?
1 Answers
Models equipped with small-displacement turbocharged engines that do not meet the China VI emission standards are generally fitted with particulate filters, and most German-made vehicles come with particulate filters. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, 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. How particulate filters work: 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. The densely arranged bag-type filter inside captures the carbon soot particles on a metal fiber felt filter. When the accumulated particles reach 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 car 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 there is a particulate filter function. Additionally, carefully check the fault codes in the manual to see if there is a "Particulate Filter" warning light indicator. 2. Check the label on the oil cap. If the oil cap clearly specifies 0W-20 grade oil, it indicates the presence of a particulate filter. 3. Inspect the exhaust pipe behind the catalytic converter to see if there is an additional cylindrical section. If present, that is the particulate filter.
