Does the 2019 Civic have a particulate filter?
2 Answers
There are 16 models of the 2019 Civic, 8 of which meet the China VI emission standards and come with a particulate filter, while the other 8 models meeting the China V emission standards do not have a particulate filter. 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 produced by 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 pipe. After passing through the densely arranged bag filters inside, the carbon particles are adsorbed onto the filter made of metal fiber felt. When the amount of adsorbed particles reaches a certain level, the burner at the end automatically ignites, burning off the carbon particles adsorbed on it and converting them into harmless carbon dioxide. To check whether the 2019 Civic has a particulate filter, you can use the following three methods: 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. Check the label on the oil filler cap. If the oil cap clearly states 0W-20 grade oil, it indicates that a particulate filter is installed. Check whether there is a cylindrical section on the exhaust pipe behind the three-way catalytic converter. If there is, that is the particulate filter.
Does the 2019 Civic have a particulate filter? This question often comes up in owner group chats. Having driven older Civic gasoline models for years, I can say particulate filters are mainly for diesel engines to reduce particulates, and generally aren't installed on gasoline cars. Most 2019 Honda Civics sold globally came with 1.0T or 1.5T gasoline engines - their exhaust systems meet standards with just a catalytic converter. Some European diesel versions might have DPFs, but diesel Civics aren't common. The maintenance manual doesn't mention it, and owners report simple exhaust cleaning with no regeneration needed. While some newer Civic models now include GPFs for environmental compliance, older models don't have this hassle - just pass regular inspections normally.
