All models with TURBO engines are equipped with particulate filters. Function of particulate filters: Particulate filters can reduce soot emissions from diesel engines by over 90%. The captured particulate matter is subsequently burned off during vehicle operation. Principle of particulate filters: Diesel particulate filters are coated with platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by diesel engines enters the particulate filter through a dedicated pipe. After passing through its densely arranged bag-type filter, the carbon particles are adsorbed onto the filter made of metal fiber felt. When the adsorbed particulate matter reaches a certain level, the burner at the end automatically ignites and burns, converting the carbon particles into harmless carbon dioxide that is then discharged.

















Recently, while helping a friend look at used cars, I noticed that many models now come equipped with particulate filters. Basically, all models with the 1.5T engine are fitted with them, including SUVs like the CR-V, Breeze, and UR-V. For sedans, the turbocharged versions of the Civic and Accord also come standard with them, though the new Odyssey hybrid doesn’t have one. My hybrid CR-V doesn’t have this either, probably because hybrid emissions already meet standards. Friends driving cars with these filters should be mindful—regular highway driving can help prevent clogging. Avoid frequent short trips, as this can lead to increased fuel consumption, speed limitations, and costly repairs. When buying a used Honda now, remember to check the environmental compliance list—most models meeting China VI-B standards come with this feature.

As a seasoned driver with six years of experience, I've noticed that most turbocharged models come equipped with a particulate filter. My neighbor's Civic had to visit the dealership multiple times last year due to a clogged filter. All 1.5T models like the CR-V, Breeze, and Vezel have it installed, even larger five-seaters like the UR-V. It's practically unavoidable if you opt for the gasoline version, but hybrid models like the Accord Hybrid don't have this issue. When helping my cousin pick up his car, I specifically checked the undercarriage and spotted a canister-like device in the middle section of the exhaust pipe. I recommend fellow drivers to take their cars on a high-speed run every 5,000 kilometers to burn off carbon deposits with the exhaust heat. Northern owners should be especially cautious, as short trips during winter are particularly damaging to this component.

Last time I went to the 4S shop for and chatted with the mechanic, he said that now eight out of ten new Honda cars come with a particulate filter. The 1.5T models can't escape it, such as popular models like the Civic, CR-V, Breeze, and UR-V. However, the Fit doesn't have it, and neither does the hybrid Accord. A friend's 2.0 Crown doesn't need one, but the 1.5T Crown does. The mechanic said that if the filter gets clogged, the fault light will come on, the power will become worse, and it will consume more fuel. He advised us not to smoke in the car, as the ash can easily clog the filter. I drive an old 2.0 Accord and don't have this worry.

After comparing the specifications of several models, it was found that the particulate filters are mainly installed on turbocharged models. The 1.5T engine models are basically equipped with them as standard, such as the entire Civic lineup, the gasoline version of CR-V, and the 240 Turbo variant of the Avancier. Naturally aspirated models like the Fit and the Lingpai do not require them. The hybrid systems are a special case—the Accord Hybrid doesn't have a particulate filter, but the CR-V Hybrid does. Just saw a discussion in a car owners' group saying that frequent start-stop city driving is the most damaging to the particulate filter. An UR-V owner who commutes just two kilometers daily ended up with a clogged filter in half a year, doubling the fuel consumption.

I've seen vehicles with clogged particulate filters during repairs, mainly in the 1.5T models. The CR-V is the most common, followed by the Civic and Breeze. The Avancier 1.5T also has this issue, but it's relatively rare in the UR-V. The hybrid version has a different design - the Accord hybrid can meet standards without a particulate filter. I once handled a completely clogged CR-V filter - when removed, it was entirely covered in black soot. The owner mentioned noticing reduced acceleration power half a year ago. I recommend developing the habit of checking the exhaust monitoring light. Using 95-octane fuel usually helps. For city commuting, you're better off buying a vehicle that doesn't require a particulate filter - it's much less hassle.
