Does the Q5L have a particulate filter?

[LeAurora]

q5l has a particulate filter. The Q5L has a total of 10 models, all equipped with particulate filters to meet China's National 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 matter is subsequently burned off during vehicle operation. Working principle of the particulate filter: The diesel particulate filter is coated with platinum, rhodium, and palladium metals. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate trap through a dedicated pipe. After passing through its densely arranged bag-type filter, the carbon 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, turning the adsorbed carbon particles into harmless carbon dioxide that is then discharged. To check whether the Q5L 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 there is a particulate filter function. In addition, you can carefully check the fault codes in the manual to see if there is a "particulate filter" warning light indicator. Check the label above the oil filler cap. If the oil cap clearly indicates the use of 0W-20 grade oil, it means the vehicle is equipped with 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.
