DPFs clogged with soot and ash hurt engine performance and raise running costs. MSG Equipment compares thermal and chemical cleaning methods.
Diesel particulate filters (DPFs) cut harmful emissions from diesel engines, but over time they clog with soot and ash, reducing performance and raising operating costs for commercial vehicles. MSG Equipment stresses that regular cleaning is essential for both performance and emissions compliance.
Methods highlighted in the article:
- Thermal regeneration – soot is burned off by raising exhaust temperature; it runs automatically in modern engines but cannot remove ash.
- Chemical cleaning – a cleaning agent is sprayed in through the pressure sensor port with the filter in place, or poured into a removed filter which is then rinsed with water.
The article also covers how these methods relate to MSG Equipment’s MS900 cleaning stand.
