What is a Diesel Particulate Filter?

A diesel particulate filter, also known as a DPF, is a device that captures and stores exhaust soot to reduce emissions from diesel engines. It is designed to improve air quality by reducing the amount of harmful particulate matter that is released into the atmosphere.

How Does a Diesel Particulate Filter Work?

A diesel particulate filter works by trapping and holding soot particles from the exhaust gas. As the soot builds up, the filter becomes clogged, which can lead to reduced engine performance and increased fuel consumption. To prevent this, the filter must be periodically cleaned or replaced.
