Particulate Filter Module
Cummins®

The Particulate Filter Module (Part Number: 2871581) manufactured by Cummins® is an essential component of the commercial truck's exhaust system. It is designed to reduce emissions of harmful particles, such as soot and ash, from the exhaust gases produced by the truck's engine. The particulate filter module works by trapping and collecting these particles as they pass through the exhaust system. This is achieved through a combination of physical filtration and chemical processes. The module consists of a housing that contains a ceramic filter element with numerous tiny channels or pores. As exhaust gases flow through the filter, the particulate matter gets trapped on the surfaces of the ceramic filter. The porous structure of the filter allows the gases to pass through while capturing the particles, preventing them from being released into the environment. Over time, the particulate matter accumulates on the filter, leading to a gradual increase in exhaust system backpressure. To prevent excessive backpressure and maintain optimal performance, the particulate filter module employs a process called regeneration. During regeneration, the accumulated particulate matter is burned off, either passively or actively, to clean the filter. Passive regeneration occurs naturally at higher exhaust temperatures, while active regeneration involves the injection of fuel or an oxidizing agent to raise the temperature and facilitate the combustion of trapped particles. In summary, the Cummins® Particulate Filter Module (Part Number: 2871581) plays a crucial role in reducing harmful emissions from commercial truck engines. By capturing and burning off particulate matter, it helps improve air quality and ensures compliance with environmental regulations.
