Does the Highlander Have a Particulate Filter?
1 Answers
The Highlander complies with the China VI emission standards. It does not have a particulate filter. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they enter the atmosphere. It can reduce soot emissions from 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 like platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate trap through a dedicated pipe. Inside, a densely arranged bag-type filter captures the carbon particles on a metal fiber mat filter. When the accumulated particles reach a certain level, a burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide. To check if the Highlander has a particulate filter, you can use the following three methods: Review the and to see if there is a particulate filter function. Additionally, carefully check the fault codes in the manual to see if there is a "particulate filter" warning light indicator. Check the label on the oil cap. If the oil cap clearly indicates the use of 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Look behind the three-way catalytic converter to see if there is a cylindrical section on the exhaust pipe. If present, that is the particulate filter.
