Do China VI Cars Have Particulate Filters?
3 Answers
China VI cars have particulate filters. Function of particulate filters: Particulate filters can reduce soot produced by diesel engines by more than 90%. The captured particulate emissions are subsequently burned off during vehicle operation. Application technology of particulate filters: Particulate filters utilize advanced electronic control systems, catalytic coatings, and fuel-additive catalysts. Principle of particulate filters: Diesel particulate filters are coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by diesel engines enters the exhaust particulate trap through a dedicated pipeline. After passing through the densely arranged bag-type filters inside, the carbon soot particles are adsorbed onto the filter made of metal fiber felt. When the adsorption of particles reaches a certain level, the burner at the end automatically ignites and burns, converting the adsorbed carbon soot particles into harmless carbon dioxide that is then released.
Bro, most China VI standard cars are equipped with particulate filters. I noticed this when driving my own China VI car. This thing is designed to reduce small particulate pollutants in exhaust emissions, making it both eco-friendly and practical. Last month during maintenance, the technician specifically reminded me to watch out for clogging, otherwise the car's power could be affected or even trigger a warning. China VI is introduced under the country's strict emission regulations. Gasoline cars commonly use GPF while diesel ones use DPF – basically standard equipment for new cars now. Without it, emissions would exceed limits and fail annual inspections. When driving normally, avoid frequent short trips. Running on highways allows the system to automatically clean and maintain it, which saves a lot of hassle. Before buying a car, check the configuration sheet or directly ask the salesperson to confirm its presence to avoid regrets. Additionally, China VI cars are generally more environmentally friendly, improving urban air quality – a benefit for everyone. Of course, the cost is slightly higher but worth it.
From a technical perspective, China VI-compliant passenger cars are generally equipped with a particulate filter—GPF for gasoline models and DPF for diesel models—which functions similarly to a sieve to trap harmful particulate matter and meet stringent emission standards. The principle involves capturing particles as exhaust gases pass through, preventing air pollution. However, prolonged use may lead to clogging, affecting performance. Owners should refer to the manual for regular maintenance and avoid excessive low-temperature, short-distance driving. Most brands have made this device standard after the implementation of China VI, as older standards could not meet the new requirements. If you notice a drop in power or a warning light while driving daily, inspect it promptly to avoid increased fuel consumption and damage to other components. The nationwide adoption of China VI aims at environmental protection, so choosing a vehicle with a particulate filter is advisable—just remember to use genuine fuel and perform proper maintenance for convenience.
