Does Changan vehicles have particulate filters?
1 Answers
Some Changan models are equipped with particulate filters, while models using the Blue Whale 1.4T and 1.5T engines do not have particulate filters, such as the Changan Eado Plus model. Working principle and function of particulate filters: The particulate filter consists of honeycomb-shaped ceramics with a certain pore density. Exhaust gas passes through the alternately blocked honeycomb-shaped porous ceramic filter body, forcing the exhaust flow to pass through the pore walls. Particulates are captured and filtered through four methods: diffusion, interception, gravity, and inertia. When particulates accumulate to a certain extent, GPF regeneration is triggered, oxidizing the captured carbon particulates with oxygen to consume them, thus completing a full cycle of GPF operation. Currently, most China VI models are equipped with particulate filters. Methods to check if a vehicle has a particulate filter: The user manual and instruction manual include information on whether the vehicle is equipped with a particulate filter. Additionally, you can check online by logging into the "Motor Vehicle Environmental Protection Network," entering the "Public Query Platform," and selecting "Production and Import Queries Before 2017" or "Production and Import Queries After January 1, 2017" based on the production date. Enter the VIN code and the last 6 digits of the engine number of the vehicle you want to query. After entering the query, you can see the Light-Duty Gasoline Vehicle Environmental Information On-board List. If the vehicle has a particulate filter, the manufacturer will be displayed; if not, it will show "None."
