Does the 2021 CRV have a particulate filter?

[Hugh]

The 2021 Honda CRV is equipped with a particulate filter to meet the China VI emission standards. The particulate filter is a ceramic filter installed in the diesel engine's exhaust system, designed to capture particulate emissions before they enter the atmosphere. It can reduce the soot produced by diesel engines by more than ninety percent, and the captured particulate emissions are subsequently burned off during vehicle operation. Diesel engine pollution mainly comes from three aspects—particulate emissions, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Among them, particulate emissions (soot) are mostly composed of tiny particles of carbon or carbides (size less than 4-20μm). 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 pipeline. 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 adsorption of particles reaches a certain level, the burner at the end automatically ignites, burning off the adsorbed carbon soot particles and converting them into harmless carbon dioxide for release. To check whether the 2021 CRV has a particulate filter, you can use the following three methods: Check the and to see if there is a 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. Check the label above the oil filler cap. If the oil cap clearly indicates 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. 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.
