2594363C91 | Genuine International® Diesel Particulate Filter

Functions: 
Reducing emissions: By effectively trapping and eliminating particulate matter, DPFs play a vital role in reducing air pollution and improving air quality.   
Trapping particulate matter: The primary function of a DPF is to capture and store soot and other particulate matter from diesel exhaust gases. The filter's porous ceramic wall traps these particles, preventing them from being released into the atmosphere.   
Regeneration: To prevent the DPF from becoming clogged, a process called regeneration is necessary. This involves burning off the trapped particulate matter at high temperatures. Regeneration can occur passively, using the engine's heat, or actively, through the injection of additional fuel into the exhaust system.
