Which Cars Are Equipped with Particulate Filters?

[LaBrandon]

Models equipped with small-displacement turbocharged engines that do not meet the China VI emission standards are fitted with particulate filters. 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: Diesel particulate filters are coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by diesel engines enters the particulate filter through a dedicated pipeline. The densely arranged bag filters inside capture the carbon particles on a filter made of metal fiber felt. When the accumulated particulate matter 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 car is equipped with a particulate filter, you can use the following three methods: Refer to the and 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. Check the label on the oil cap. If the oil cap clearly indicates the use of 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Look behind the catalytic converter on the exhaust pipe for an additional cylindrical section. If present, that is the particulate filter.
