The 2020 Tharu has 6 models that meet the National V emission standards and do not come with a particulate filter, while the remaining 12 models meet the National VI emission standards and are equipped with a particulate filter. A particulate filter is a ceramic filter installed in the exhaust system of a diesel engine, which captures particulate emissions before they enter the atmosphere. It can reduce 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 exhaust particulate filter through a dedicated pipe. After passing through the densely arranged bag-type filters inside, 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 and burns, turning the adsorbed carbon particles into harmless carbon dioxide that is then expelled. To check whether the 2020 Tharu is equipped with a particulate filter, you can use the following three methods: 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. Check the label on the oil cap. If the oil cap clearly states 0W-20 grade oil, it indicates that a particulate filter is installed. Look at the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section. If there is, that is the particulate filter.
