Does the Highlander Have a Particulate Filter?
1 Answers
The Highlander does not come with a particulate filter across all its models. There are currently 9 available Highlander models on sale, none of which are equipped with a particulate filter, yet they still comply with the China VI emission standards. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they are released into the atmosphere. It can reduce the soot produced by diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. 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 particulate filter through a dedicated pipe. Inside, a densely arranged bag-type filter captures the carbon particles on a metal fiber felt filter. When the accumulation of particles reaches a certain level, a burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide that is then released. To check if a Highlander has a particulate filter, you can use the following three methods: 1. 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. 2. Look at the label on the oil filler cap. If the cap clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. 3. Inspect the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section. If present, that is the particulate filter.
