DPF Installation
A Diesel Particulate Filter (DPF) is placed between the engine and the muffler to eliminate suspended particulate matter (SPM) from the exhaust of diesel engines.
The operation of the particulate filter involves alternately sealing the ends of the honeycomb's porous structure, allowing the ceramic walls to effectively trap and remove particulate matter (PM).
