Which Honda models are equipped with particulate filters?

Some Honda models are equipped with particulate filters. All turbocharged (TURBO) models have particulate filters installed. Since these are turbocharged engines, installing a particulate filter is necessary to meet the National VI (China 6) emission standards. Some models with naturally aspirated engines do not require particulate filters, as they can more easily meet the National VI emission standards. If your vehicle is equipped with a particulate filter, please note the following: Use low-ash engine oil. During the particulate filter regeneration process, much of the ash cannot be burned. The ash produced by burning engine oil enters the particulate filter and is difficult to burn off during regeneration. Prolonged use of high-ash engine oil will accelerate particulate filter clogging, requiring removal and cleaning of the filter, which increases maintenance costs. Use high-quality fuel, which contains lower levels of sulfur, phosphorus, and impurities, to prevent particulate filter clogging. Learn the regeneration method for the particulate filter. This is very important. Increase the vehicle speed to over 80 km/h, then release the accelerator and let the vehicle coast for a while. During this time, the engine does not inject fuel, and oxygen does not participate in combustion but directly enters the particulate filter, increasing the oxygen supply and raising the filter's temperature. This burns off the tiny solid emissions in the particulate filter. Repeating this process several times will successfully regenerate the particulate filter.
I'm an auto mechanic and have worked on many Honda vehicles. Currently, most China VI emission standard models are equipped with particulate filters, and Honda is no exception. This is most noticeable in 1.5T models like the popular CR-V, Breeze, Accord, Integra, and Civic turbocharged variants. Naturally aspirated engines like the Fit 1.5L don't require one. Recently, I've handled many cases where owners complain about clogging issues, especially vehicles frequently driven short distances in winter. My advice is to regularly drive on highways to raise exhaust temperatures, which can help burn off carbon deposits. If the particulate filter warning light appears on the dashboard, don't ignore it - take the car to an authorized dealer immediately for regeneration treatment.
