Does the 2021 Sagitar have a particulate filter?

[DeHaley]

2021 Sagitar is equipped with a particulate filter to meet the China VI emission standard. The particulate filter is a ceramic filter installed in the diesel engine emission system, which can capture 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. The pollution from diesel engines mainly comes from three aspects - particulate emissions, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Among them, particulate emissions (soot) are mostly composed of tiny particles of carbon or carbide (size less than 4-20μm). Working principle of the particulate filter: The diesel particulate filter is coated with metals platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate filter through a special pipeline. After passing through its densely arranged bag-type filter, the carbon smoke particles are adsorbed on 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, burning off the carbon smoke particles adsorbed on it and turning them into harmless carbon dioxide. To check whether the 2021 Sagitar is equipped with 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. In addition, you can also carefully check the fault codes in the manual to see if there is a "particulate filter" fault light indicator. Check the label above the oil filler cap. If the oil filler cap clearly indicates 0W-20 grade oil, it means that a particulate filter is installed. 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.
