Does the Levin have a particulate filter?

[OBrynlee]

The Levin does not have a particulate filter. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, which captures particulate emissions before they enter the atmosphere. Function of the particulate filter: The particulate filter can reduce the soot produced by diesel engines by more than 90%. The captured particulate emissions are then burned off during vehicle operation. 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 filters inside, the carbon particles are adsorbed on the filter made of metal fiber felt. When the amount of adsorbed 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 emitted.
