Does the 2021 new CRV have a particulate filter?
1 Answers
2021 CRV meets the China VI emission standard. It is equipped with a particulate filter. A particulate filter is a ceramic filter installed in the diesel engine emission system, which can capture 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 engine exhaust particulate trap through a dedicated pipeline. After passing through its densely arranged bag-type filter, the carbon smoke particles are adsorbed on the filter made of metal fiber felt. When the adsorption of particles reaches a certain level, the burner at the end automatically ignites and burns, turning the adsorbed carbon smoke particles into harmless carbon dioxide that is then expelled. 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 check 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.
