Does the 2021 Sagitar come with a particulate filter?
1 Answers
The 2021 Sagitar is equipped with a particulate filter to meet the China VI emission standards. The particulate filter is a ceramic filter installed in the diesel engine's emission system, which captures particulate emissions before they enter the atmosphere. It can reduce the soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Pollution from diesel engines mainly comes from three sources—particulate emissions, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Among these, particulate emissions (soot) are mostly composed of tiny particles of carbon or carbon compounds (smaller than 4-20μm). How the particulate filter works: The diesel particulate filter is coated with metals like 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 its densely arranged bag-type filter, the carbon soot particles are adsorbed onto a filter made of metal fiber felt. When the adsorbed particulate matter reaches a certain level, the burner at the end automatically ignites, burning off the carbon soot particles adsorbed on it and converting them into harmless carbon dioxide. To check whether the 2021 Sagitar 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 the particulate filter function is mentioned. 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 filler cap. If it clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look behind the catalytic converter to see if there is an additional cylindrical section on the exhaust pipe. If there is, that is the particulate filter.
