The gasoline-powered Honda CR-V is equipped with a particulate filter, while the hybrid version does not have one. The particulate filter can reduce the particulate matter in the engine's exhaust emissions, recycle them, decrease vehicle exhaust emissions, enhance the vehicle's environmental friendliness, and reduce atmospheric pollution. A particulate filter is a ceramic filter installed in the diesel engine's exhaust system, capable of capturing particulate emissions before they enter the atmosphere. It can reduce the soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. 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 filter through a dedicated pipe. After passing through the densely arranged bag-type filters inside, the carbon 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 particles and converting them into harmless carbon dioxide. To check whether the new Honda CR-V comes with a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, 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 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 present, that is the particulate filter.
