[StBrianna]

Buick Regal 2020 and 2021 models are equipped with particulate filters. Below is more information about particulate filters: Introduction: The Diesel Particulate Filter (DPF) is a ceramic filter installed in the exhaust system of diesel engines, which captures particulate emissions before they enter the atmosphere. Function: The filter utilizes an advanced electronic control system, catalytic coating, and fuel-borne catalyst (FBC). This fuel-borne catalyst contains metals such as cerium, iron, and platinum. These materials are added to the fuel in specific proportions, and with the help of the engine control system, they not only control the amount of particulate emissions but also regulate the emissions of pollutants such as hydrocarbons and other harmful gases.
