Background on Diesel Particulate Filters

First, it’s important to understand what a diesel particulate filter is and its role in reducing emissions. A DPF is an emission control device that captures and stores exhaust soot particles before releasing cleaner exhaust gas. It’s designed to reduce harmful emissions such as nitrogen oxides (NOx), hydrocarbons (HC) and carbon monoxide (CO).

In order for a DPF to function properly, the soot trapped within needs to be burned off through a process called regeneration. This happens when the temperature of the exhaust gases reaches a certain point, typically achieved by driving at high speeds or through an active heating system.
