Does the 2021 Lavida have a particulate filter?
1 Answers
The 2021 Lavida is equipped with a particulate filter to meet the China VI emission standards. A particulate filter is a ceramic filter installed in the diesel engine's emission system, designed to capture particulate matter before it is released into the atmosphere. It can reduce soot emissions from diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. Diesel engine pollution mainly comes from three sources—particulate matter, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Among these, particulate matter (soot) is primarily composed of tiny carbon or carbon compound particles (smaller than 4-20μm in size). How the particulate filter works: 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 particulate filter through a dedicated pipe. Inside, a densely arranged bag-type filter captures the soot particles on a metal fiber felt filter. When the accumulated soot reaches a certain level, an automatic igniter at the end burns off the captured carbon particles, converting them into harmless carbon dioxide that is then released. To check whether the 2021 Lavida has a particulate filter, you can use the following three methods: 1. Refer to the Owner's Maintenance Manual and Owner's User Manual 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. 2. Check the label on the oil filler cap. If it clearly states the use of 0W-20 grade oil, it indicates the presence of a particulate filter. 3. Look behind the catalytic converter on the exhaust pipe for a cylindrical section. If present, that is the particulate filter.
