Do all China VI emission vehicles have particulate filters?
1 Answers
Most small-displacement naturally aspirated models can relatively easily meet the China VI emission standards, so they do not come equipped with particulate filters. However, small-displacement turbocharged engines that do not meet the emission standards are equipped with particulate filters. Most Japanese models do not have particulate filters, while most German models do. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, which captures 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 away 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 trap through a dedicated pipeline. After passing through its densely arranged bag-type filter, 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 and burns, turning the adsorbed carbon soot particles into harmless carbon dioxide that is then expelled. To check whether a vehicle 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.
