What is a diesel particulate filter?

A DPF is a device installed in the exhaust stream of diesel engines made after Jan. 1, 2007 in response to more stringent emission regulations.

The DPF is designed to remove the particulate matter (soot) from the exhaust. In vehicles with a DPF, exhaust flows through an open inlet channel and is restricted at the plugged end, where it is forced through porous walls that trap soot. The exhaust then passes through the wall and out of the adjacent cell where the outlet end is open.

Adverse health effects have been linked to harmful particulate matter found in diesel emissions. The carcinogenic components can cause asthma, respiratory distress and cardiovascular issues. The most harmful of these particles are less than 10 microns in size, and are able to get into the deepest regions of the human respiratory system.

DPF Preventive Maintenance

While the DPFs do their job in removing particulate matter, the soot left behind can build up and reduce the filter’s effectiveness. A diesel engine can last more than 20 years, but the DPF must be serviced and/or replaced multiple times in that time span. The more the soot becomes compacted in the filter, the shorter the life of the filter.

Benefits of a clean DPF:

  • Improved vehicle performance

  • Increased fuel economy

  • Less downtime

  • Extended DPF life

  • Experience fewer regenerations

  • Lower maintenance costs

Air Cleaning

*Recommended for drivers under time constraints

  • Visually inspect and airflow test DPF

    • Record any blocked or failed filter cells

    • Record any defects or damage

  • Air clean filter

  • Post cleaning inspection and flow testing

    • Record any blocked or failed filter cells

    • Record any defects or damage

    • Results comparison

Air and Thermal Cleaning

*Recommended for maximum soot and ash removal.

Air cleaning is the only step many competitors complete in their DPF cleaning process, however, at L & T Truck Service goes beyond the standard, offering thermal cleaning. This industry leading cleaning procedure is designed to get a filter back to its OE air flow specifications – between 0.5-1.0 on the flow meter.

  • Visually inspect and airflow test DPF

    • Record any blocked or failed filter cells

    • Record any defects or damage

  • Preliminary air cleaning

  • Bake filter for 8 to 10 hours to oxidize trapped soot and loosen deposits

  • Repeat air cleaning to blow out soot freed from thermal cleaning

  • Post cleaning inspection and flow testing

    • Record any blocked or failed filter cells

    • Record any defects or damage

    • Results comparison.
