Do all China VI vehicles have particulate filters?

[DelWeston]

Most China VI vehicles are equipped with particulate filters. Here are relevant introductions about particulate filters: Introduction to particulate filters: The Diesel Particulate Filter (DPF) is a ceramic filter installed in the diesel engine emission system, which can capture particulate emissions before they enter the atmosphere. Function of particulate filters: Particulate filters can reduce soot produced by diesel engines by more than 90%. The captured particulate emissions are subsequently burned off during vehicle operation. The basic working principle is: If 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 special pipeline. After passing through its densely arranged bag filters, the carbon particles are adsorbed on the filter made of metal fiber felt.
