Does the 2021 CT5 have a particulate filter?

The 2021 Cadillac CT5 does not have a particulate filter. All 11 models of the 2021 Cadillac CT5 do not come with a particulate filter. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines to capture particulate emissions before they enter the atmosphere. It can reduce soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. How a particulate filter works: The diesel particulate filter is coated with metals like 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 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 carbon particles and converting them into harmless carbon dioxide. To check if the 2021 Cadillac CT5 has a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, carefully review 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 it clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look behind the three-way catalytic converter on the exhaust pipe for a cylindrical section. If present, that is the particulate filter.
