Does Changan's China VI vehicles have a particulate filter?
3 Answers
Changan's China VI vehicles have a particulate filter. The particulate filter can reduce the particles in the engine exhaust emissions, recycle them, reduce vehicle exhaust emissions, increase the environmental friendliness of the vehicle, and reduce pollution to the atmosphere. To check whether the vehicle is equipped with a particulate filter, you can use the following 3 methods: Check the and to see if there is a particulate filter function. In addition, you can carefully check the fault codes in the manual to see if there is a "particulate filter" fault light indicator. Check the label above the oil filler cap. If the oil filler cap clearly indicates 0W-20 grade oil, it means that the vehicle is equipped with a particulate filter. Check whether there is a cylindrical section on the exhaust pipe behind the three-way catalytic converter. If there is, that is the particulate filter. Location of the particulate filter: The particulate filter is located behind the three-way catalytic converter and in front of the muffler, surrounded by the front and rear oxygen sensors.
Yes, Changan's China VI emission standard vehicles are generally equipped with a particulate filter (GPF), which is designed to comply with China's latest emission regulations and effectively reduce fine particulate matter and PM2.5 in exhaust gases. With over a decade of experience in car repairs, I've commonly seen this device in Changan's CS and UNI series models meeting the China VI standard. It operates silently, but is prone to clogging during city traffic congestion, affecting power and fuel consumption. I recommend owners to frequently drive on highways to maintain high engine temperatures for automatic cleaning of blockages. If neglected, repairs could cost several hundred to over a thousand yuan. However, there are significant benefits—besides protecting the environment and reducing smog, it also extends engine life and minimizes carbon buildup issues. Overall, this is a mandatory configuration for China VI vehicles. As a mainstream domestic brand, Changan certainly doesn't lag behind in this aspect. With regular maintenance, there's little to worry about.
I've been driving my Changan UNI-T China VI version for almost a year now, and the 4S store confirmed it's indeed equipped with a particulate filter. There haven't been any issues during my daily urban commutes, but once the dashboard warning light flashed, indicating a clogged particulate filter. Following the manual's instructions, I drove on the highway for half an hour and it automatically cleared. Nowadays, cars are so smart they notify you about the regeneration process, which is very convenient. When purchasing the car, I was told this feature helps protect the environment and reduce urban air pollution. Although it occasionally increases fuel consumption by about half a liter, I think it's worth it. My friends who drive Geely or Volkswagen China VI vehicles have similar experiences. Changan's technology is quite mature, so there's no need to worry about extra hassles. Overall, this is standard equipment under the China VI emission standards, including Changan's newly launched Oshan series. It makes driving both safe and worry-free.
