Do all China 6b vehicles have particulate filters?

Not all China 6b vehicles have particulate filters. After the China 6 standard was released, automakers found it almost impossible to meet the standard without changing design direction, R&D investment, and power performance. Therefore, most models that comply with the China 6 standard are equipped with particulate filters. However, a very few models without particulate filters also meet the China 6 emission standard, as follows: Toyota: Camry, RAV4, C-HR, etc.; Honda: Lingpai Hybrid, CR-V Hybrid, Accord Hybrid, etc.; Mazda: Axela, CX-30, CX-5, etc.; BYD: Qin PLUS DM-i, Song PLUS DM-i. To check whether a vehicle has a particulate filter, you can use the following three methods: Check the "Owner's Maintenance Manual" and "Owner's User Manual" to see if there is a particulate filter function. Additionally, you can carefully check the fault codes in the manual to see if there is a "particulate filter" fault light indicator. Check the label on the oil filler cap. If the oil cap clearly states 0W-20 grade oil, it indicates 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.
I've noticed many people discussing vehicle emissions lately. The China 6b standard was actually established to reduce pollution. For diesel vehicles, almost every model is now equipped with a particulate filter to capture fine particles in exhaust gases, reducing PM2.5 emissions and meeting environmental requirements.
For gasoline vehicles, it depends on the engine type: direct injection gasoline engines often come with particulate filters to control particle emissions, but naturally aspirated gasoline engines may not require them as they can meet standards through optimized combustion systems. Therefore, not all China 6b vehicles come standard with particulate filters - it ultimately depends on the engine design of the specific model.
I recommend checking specifications or consulting with dealerships before purchasing to avoid potential maintenance issues later. Regarding maintenance, particulate filters may become clogged over time and typically require regular highway driving to regenerate and clear carbon buildup. Overall, they're quite hassle-free to operate while delivering better environmental performance.
