Does the 10th-generation Accord have a particulate filter?
1 Answers
The 10th-generation Accord is equipped with a particulate filter to meet the China VI emission standards. A particulate filter is a ceramic filter installed in the diesel engine's emission system, designed to capture particulate matter before it enters the atmosphere. It can reduce the soot produced by diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. Diesel engine pollution mainly comes from four aspects—particulate matter, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Among these, particulate matter (soot) is mostly composed of tiny particles of carbon or carbides (with sizes smaller than 4-20μm). 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. After passing through the densely arranged bag-type filters inside, the carbon soot 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 soot particles adsorbed on it and converting them into harmless carbon dioxide. To check whether the 10th-generation Accord has a particulate filter, you can use the following three methods: Check the Owner's Maintenance Manual and Owner's User Manual to see if there is a particulate filter function. Additionally, you can carefully review the fault codes in the manual to check if there is a "particulate filter" warning light indicator. Check the label above the oil filler cap. If it clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look behind the three-way catalytic converter to see if there is a cylindrical section on the exhaust pipe. If there is, that is the particulate filter.
