Does the National VI Accord have a particulate filter?
1 Answers
The National VI Accord is equipped with a particulate filter to meet the National VI emission standards. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, which captures 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. Working principle of the particulate filter: 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 pipeline. The densely arranged bag-type filters inside the trap capture the carbon particles on a filter made of metal fiber felt. When the accumulated particles reach a certain level, the burner at the end automatically ignites and burns, converting the captured carbon particles into harmless carbon dioxide. To determine whether the Tiguan has a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, you can carefully review 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. Inspect the exhaust pipe behind the three-way catalytic converter to see if there is a cylindrical section. If present, that is the particulate filter.
