Does the 2021 Tharu come with a particulate filter?

The 2021 Tharu is equipped with a particulate filter to meet the China VI emission standards. A particulate filter is a ceramic filter installed in the diesel engine's exhaust system that captures particulate emissions before they enter the atmosphere. It can reduce soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Diesel engine pollution mainly comes from three sources—particulate emissions, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Particulate emissions (soot) are mostly composed of tiny particles of carbon or carbide (smaller than 4-20μm). How the particulate filter works: 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 exhaust particulate filter through a dedicated pipe. After passing through the densely arranged bag-type filter 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, burning off the adsorbed carbon soot particles and converting them into harmless carbon dioxide. To check whether the 2021 Tharu has a particulate filter, you can use the following three methods: Check the and to see if the particulate filter function is mentioned. Additionally, carefully review the fault codes in the manual to check for a "particulate filter" warning light indicator. Check the label on the oil filler cap. If the oil cap clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look behind the three-way catalytic converter to see if there is a cylindrical section on the exhaust pipe. If present, that is the particulate filter.
My 2021 Tharu feels quite stable to drive, and I know it comes with a gasoline particulate filter (GPF), as the China 6 emission standards now require all gasoline vehicles to have one. The GPF helps reduce particulate pollutants in the exhaust, making the car more environmentally friendly. However, when driving mostly in the city, it might get slightly clogged, leading to reduced power or slightly higher fuel consumption, so I occasionally take it on the highway to clean it out. Overall, with the GPF installed, emissions are much cleaner, making it much more eco-friendly. As an owner, I remind the mechanic to check it during maintenance to avoid long-term clogging issues. Although the initial purchase cost didn’t increase much, it’s easier to maintain and safer to drive on the road.
I particularly admire SUVs like the Tharu. The 2021 model has upgraded its emission system, definitely equipped with a particulate filter. This device intercepts fine particles in the exhaust system, significantly reducing PM2.5 emissions, making it much more environmentally friendly than older models. Driving feels smoother, with quicker response, and avoids the black smoke issues common in cars without a GPF. As a car enthusiast, I've researched many models, and the Tharu's GPF design, paired with its turbocharged engine, maintains excellent performance. However, prolonged low-speed driving can lead to dust accumulation, so I recommend regular maintenance and cleaning to prevent power loss. Its presence contributes to improving China's air quality, and I genuinely recommend it to friends who prioritize environmental protection.
During the repair process of Volkswagen vehicles, it is common to see that the 2021 Tharu comes standard with a gasoline particulate filter (GPF), usually located at the front end of the exhaust pipe. This device prevents the emission of fine particles, but it is prone to carbon buildup during city traffic congestion, which can trigger the exhaust warning light or cause sluggish acceleration. It is recommended that owners check whether the GPF is clogged every 5,000 kilometers or so. Cleaning can be done by revving the engine at high speed for a few seconds. Severe clogging may damage the sensor, and the repair cost is not low. The installation of the GPF complies with the China VI emission regulations, reducing exhaust pollution. From a professional perspective, with proper maintenance, it can last for several years without failure, so don't neglect daily upkeep.
