Does the Avalon have a particulate filter?

[DelKimberly]

The Avalon 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, designed to capture 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. Among these, particulate emissions (soot) are mostly composed of tiny carbon or carbon compound particles (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 trap through a dedicated pipe. The densely arranged bag-type filters inside capture the carbon soot particles on a metal fiber felt filter. When the accumulated soot reaches a certain level, the burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide. To check whether the Avalon 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 any "particulate filter" warning light indicators. Check the label above the oil filler cap. If it clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look behind the three-way catalytic converter on the exhaust pipe for a cylindrical section. If present, it is the particulate filter.
