How it Works - Diesel Particulate Filter (DPF)

How a Diesel Particulate Filter (DPF) Works

Diesel particulate filters (DPFs) and gasoline particulate filters (GPFs) are two types of emission control technologies used in vehicles to reduce the amount of harmful particulate matter released into the air. Both types of filters work by trapping and removing particulates from the exhaust gas of a vehicle, but there are some differences.

DPFs have been used for years to reduce carbonaceous particulate matter created during the diesel combustion process. They work by trapping and then burning off particulates to limit emissions output.
