Does the Mazda CX-4 have a particulate filter?

Mazda CX-4 does not have a particulate filter. Except for the Skyactiv-X models, none of the Mazda vehicles are equipped with a particulate filter. Introduction to the particulate filter: A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, which captures particulate emissions before they enter the atmosphere. 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 particulate filter through a dedicated pipe. Inside, a densely arranged bag-type filter captures the carbon particles on a metal fiber felt filter. When the accumulation of particles reaches a certain level, the burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide that is then released.
I recently researched the emission system of the Mazda CX-4. The China VI standard version sold in China is highly likely to be equipped with a Gasoline Particulate Filter (GPF), primarily to comply with strict environmental regulations and reduce fine particulate emissions from exhaust. If you own a new model from 2020 onwards, the manufacturer generally installs this device to handle PM2.5. This is not specifically designed for diesel vehicles. Gasoline vehicles may accumulate particulates after low-speed driving, leading to a temporary drop in power. In such cases, driving at high speeds or letting the system perform automatic regeneration can clear the blockage. It's recommended to check the owner's manual or directly contact a Mazda dealer to confirm the specific model, as configurations may vary across different model years. Also, pay attention to regular maintenance to avoid GPF issues affecting fuel consumption. Overall, it's a practical environmental upgrade component.
