Does the National VI Civic have a particulate filter?
1 Answers
In the Civic series, National VI A models do not have a particulate filter, while National VI B models are equipped with a particulate filter. A particulate filter is a ceramic filter installed in the diesel engine emission system, which captures particulate emissions before they enter the atmosphere. It can reduce the soot produced by diesel engines by more than 90%, and the captured particulate emissions are 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 engine exhaust particulate trap through a dedicated pipeline. After passing through the densely arranged bag filters inside, the carbon smoke particles are adsorbed onto 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, incinerating the adsorbed carbon smoke particles into harmless carbon dioxide, which is then discharged. To check whether the Civic has a particulate filter, you can use the following three methods: Refer to 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" fault light indicator. Check the label on the oil cap. If the oil cap clearly indicates 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Look at the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section. If there is, that is the particulate filter.
