The third-generation Haval H6 is equipped with a particulate filter. The engine of the third-generation Haval H6 requires a particulate filter to minimize the proportion of pollutants in exhaust emissions, thereby meeting the China-6 emission standards while maintaining power output. A particulate filter is a ceramic filter installed in the diesel engine's emission system, which captures particulate matter before it enters the atmosphere. It can reduce the soot produced by diesel engines by more than 90%, and the captured particulate matter is 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's exhaust particulate trap through a dedicated pipeline. After passing through its densely arranged bag-type filter, 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 third-generation Haval H6 is equipped with a particulate filter, you can use the following three methods: 1. 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. 2. Check the label on the oil cap. If the oil cap clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. 3. Look behind the three-way catalytic converter on the exhaust pipe to see if there is a cylindrical section. If present, that is the particulate filter.
