A diesel particulate filter is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. As the gases pass through the filter, the filter will begin to get clogged with the soot that it has trapped. (Soot is a by-product of incomplete combustion - when the mixture of air and fuel that powers the engine fails to completely ignite). As the temperature of the exhaust gets higher, the residue heats up and turns to ash which is then expelled.

DPFs are exhaust-treatment devices that can be fitted to a wide variety of engines. DPFs trap harmful pollutants and prevent them from reaching the atmosphere, where they can cause significant environmental damage and impact to human health.

A catalytic converter is an exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. It is the most important external purification device installed in automobile exhaust system.

Captures diesel combustion exhaust and filters carbon particles. When the captured carbon particles reach a certain level, the ECU system will carry out "filter regeneration" to burn the carbon particles in the filter into carbon dioxide and discharge it to purify the filter and maintain the filtering function.
