Does the Envision Have a Particulate Filter?
1 Answers
None of the Envision models come equipped with a particulate filter. The Envision offers a total of 13 variants, none of which include a particulate filter, yet they all comply with the China VI emission standards. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they are released into the atmosphere. It can reduce soot emissions from diesel engines by over 90%, with the captured particulates being burned off during vehicle operation. How the particulate filter works: The diesel particulate filter is coated with platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the particulate filter through a dedicated pipe. The densely arranged bag-type filters inside the device capture the carbon particles on a filter made of metal fiber felt. Once the accumulated particles reach a certain level, the burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide. To check if the Envision has a particulate filter, you can use the following three methods: Refer to the and to see if the particulate filter function is mentioned. Additionally, carefully check the fault codes in the manual to see if there is a "particulate filter" warning light indicator. Check the label on the oil filler cap. If the cap specifies 0W-20 grade oil, it indicates the presence of a particulate filter. Inspect the exhaust pipe behind the catalytic converter for an additional cylindrical section. If present, that is the particulate filter.
