Does the Civic have a particulate filter?
1 Answers
In the Civic series, models meeting China 6A standards do not come with a particulate filter, while those meeting China 6B standards are equipped with one. 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 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. The densely arranged bag-type filters inside capture the carbon particles on a metal fiber felt filter. When the accumulated particles reach a certain level, the burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide. To check if a China 6-compliant Civic has a particulate filter, you can use the following three methods: Check the and to see if they mention the 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. Look at the label on the oil filler cap. If it clearly specifies 0W-20 grade oil, it indicates the presence of a particulate filter. Check if there is a cylindrical section on the exhaust pipe behind the three-way catalytic converter. If present, it is the particulate filter.
