Does the Buick Excelle have a particulate filter?

[LeKeegan]

Buick Excelle 2021 offers four models in total, none of which are equipped with a particulate filter. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, capable of capturing 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. Working principle of the particulate filter: 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 trap through a dedicated pipeline. After passing through the densely arranged bag filters inside, the carbon particles are adsorbed on the 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 carbon particles adsorbed on it, converting them into harmless carbon dioxide that is then expelled. To check whether the Buick Excelle is equipped with 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 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 behind the three-way catalytic converter to see if there is a cylindrical section on the exhaust pipe. If there is, that is the particulate filter.
