Does the 2021 14th-generation Sylphy have a particulate filter?
2 Answers
2021 14th-generation Sylphy has a total of 18 models, none of which are equipped with a particulate filter. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, which 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. Working principle of the particulate filter: 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 trap through a dedicated pipeline. After passing through the densely arranged bag filters inside, the carbon 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 particles and converting them into harmless carbon dioxide that is then expelled. To check whether the 2021 14th-generation Sylphy is equipped with a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, carefully review the fault codes in the manual to see if there is a "particulate filter" warning light indicator. Check the label on the oil cap. If the oil cap clearly states 0W-20 grade oil, it indicates the presence of 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.
Last time I worked on quite a few Sylphys, and indeed the 14th-generation 2021 Sylphy comes equipped with a particulate filter, primarily designed to meet China's National VI emission standards. It functions like a filter, trapping tiny particulate matter from the exhaust to reduce air pollution. The vehicle uses a 1.6L naturally aspirated gasoline engine, and after the emission upgrade, the manufacturer installed this component to avoid penalties for exceeding emission limits. You might not feel much difference while driving, but it's important to pay attention during regular maintenance as the particulate filter accumulates dirt. If it gets clogged, you might experience a slight drop in power, and the dashboard may show a warning light. It's recommended that owners perform maintenance every 10,000 to 20,000 kilometers to clean or replace the component. This ensures both environmental protection and uninterrupted daily use. Neglecting maintenance could lead to higher costs of several hundred yuan later on, so prevention is better than cure. In short, having this device is quite common—no need to worry too much, just follow the manual.
