FAQ

What is DPF Filter?

A DPF filter, or Diesel Particulate Filter, is a device integrated into the exhaust system of diesel engines to reduce harmful emissions. Its primary function is to trap and remove soot (particulate matter) from the exhaust gas before it is released into the atmosphere.

How It Works:

  1. Trapping Particulate Matter: The DPF has a porous structure that allows exhaust gases to pass through while capturing solid soot particles.
  2. Regeneration Process: Over time, the filter fills with soot and needs to be cleaned through a process called regeneration:

Benefits:

  • Reduces harmful emissions, particularly soot and particulate matter.
  • Helps vehicles meet stringent environmental regulations, such as EPA or Euro emissions standards.

Maintenance:

  • Regular regeneration is crucial to prevent clogging.
  • Excessive soot buildup can lead to costly repairs or DPF replacement.
  • Proper engine maintenance and the use of high-quality diesel and DEF (Diesel Exhaust Fluid) help extend the DPF's lifespan.

Common Issues:

  • Frequent clogging due to short trips or low exhaust temperatures.
  • Faulty sensors, leading to failed regeneration cycles.
  • Increased fuel consumption during active regeneration.

DPF filters are essential for modern diesel engines to comply with environmental regulations and contribute to cleaner air.

How to remove DPF filter for replacement?

Removing a Diesel Particulate Filter (DPF) for cleaning involves several steps. This can vary slightly depending on the vehicle make and model, but hereโ€™s a general guide to the process. Be sure to check your vehicleโ€™s service manual for specific instructions, as some models may require special tools or procedures.

1.ย Gather Tools and Equipment

  • Socket wrench set
  • Ratchet and extension
  • Penetrating oil or lubricant spray
  • Safety glasses and gloves
  • Floor jack and jack stands (if necessary)
  • DPF removal tool (if required for your vehicle model)
  • New gaskets or seals, if needed for reinstallation

2.ย Prepare the Vehicle

  • Park on a Level Surface: Ensure the vehicle is parked on a flat surface with the parking brake on.
  • Allow the Engine to Cool: Since the DPF gets very hot during operation, let the vehicle cool completely to avoid burns.

3.ย Access the DPF

  • Raise the Vehicle (if needed): If the DPF is located under the vehicle, use a floor jack and jack stands to lift the car and access the exhaust system.
  • Locate the DPF: The DPF is generally located in the exhaust system between the engine and the muffler.

4.ย Remove Bolts and Clamps

  • Apply Penetrating Oil: Spray penetrating oil on the bolts and clamps around the DPF to loosen any rust or corrosion, which will make removal easier.
  • Disconnect Sensors: DPFs often have temperature and pressure sensors attached. Carefully disconnect these to avoid damaging them.
  • Remove Mounting Bolts and Clamps: Use the socket wrench to remove any bolts or clamps securing the DPF in place. Keep track of these parts for reinstallation.

5.ย Remove the DPF

  • Carefully Lower the DPF: Some DPFs are heavy and may require a second person or a support stand. Carefully remove it from the exhaust assembly, ensuring you donโ€™t damage nearby components or wiring.

6. Install the new DPF

  • Replace Gaskets or Seals: If your vehicle has gaskets around the DPF, replace them before reinstalling.
  • Reconnect and Secure: Reattach the DPF using the mounting bolts and clamps, reconnect any sensors, and ensure everything is tightened securely.
  • Lower the Vehicle: If you raised the vehicle, lower it carefully.

8.ย Reset System Codes (if necessary)

  • Use a Diagnostic Tool: Some vehicles may require a DPF reset using an OBD-II diagnostic tool, especially if the DPF warning light was triggered.

After reinstalling, start the vehicle and check for any error codes. If youโ€™re unsure about any step, a professional mechanic can perform the DPF removal and cleaning.

How to Clean a DPF Filter at Home?

Cleaning DPF filter at home isn't recommended. However, some people attempt to use pressurized warm/hot water to clean the inlet side of the DPF filter.ย ย Even though the soot on the inlet side of the DPF surface can be cleaned up, the ash and soot trapped insideย the DPF filterย vesselsย will not be broken down. We did a air restriction test after the cleaning with this "home cleaning" method, and the air restriction barely changed. In conclusion, save the headache, and seek a professional DPF filter cleaning facility near you to get the DPF filter tested and cleaned professionally.ย

Why Pressure Washing Your DPF is a Costly Mistake: A Technician's Insight

How Often Should You Clean Your DPF Filter?

The frequency of DPF cleaning depends on your driving habits. Long highway drives reduce the need for frequent cleanings, but city driving with frequent stops and starts can lead to quicker clogging. On average, it's recommended to do a parked regenerationย every 1-2 weeks, and do a DPF filter cleaning every 100,000 to 150,000 miles.

It is always recommended to clean your DOC along with your DPF filter when you get a professional DPF filter cleaning service.ย 

How to know if my DPF needs cleaning?

There are several signs to watch for that indicate your Diesel Particulate Filter (DPF) may need cleaning:

1.ย Dashboard Warning Light

  • Most vehicles have a DPF warning light on the dashboard. When this light comes on, it typically means that the filter is becoming clogged and requires regeneration or cleaning.

2.ย Reduced Engine Performance

  • A clogged DPF can restrict exhaust flow, which affects engine performance. You may notice a lack of power, slower acceleration, or increased fuel consumption.

3.ย Poor Fuel Efficiency

  • When the DPF is full of soot or ash, the engine works harder, resulting in higher fuel consumption.

4.ย Frequent Regeneration Cycles

  • If you notice your vehicle is frequently going into regeneration mode (where it tries to burn off soot automatically), it could mean the DPF is becoming clogged faster than it can clean itself.

5.ย Excessive Exhaust Smoke

  • In some cases, a full DPF may result in dark exhaust smoke, as the exhaust flow becomes restricted, and unburned fuel is released from the exhaust system.

6.ย Increased Exhaust Temperatures

  • Clogged DPFs can cause excessive exhaust temperatures, as the engine tries to burn off the accumulated soot. This might lead to further damage if not addressed.

7.ย Unusual Smells

  • You may notice a strong, acrid smell from the exhaust, especially during regeneration attempts. This odor is often caused by the filter trying to burn off excess soot unsuccessfully.

If you notice any of these signs, itโ€™s a good idea to have your DPF checked and cleaned as soon as possible to avoid more serious (and costly) issues.

How is DPF cleaned?

At Diesel Emissions Specialists, we are equipped with industry-proven thermal DPF cleaning equipment. Here are the DPF cleaning process:

PRO-CLEAN

Inspect & Benchmark
  • Visual inspectionย โ€“ check for damage & evidence of upstream issues.
  • Wire/Pin testย for plugged cells.
  • Measure theย airflowย of the filter.
  • Measure the filterย weight.
  • Checkย for cracks in the brick using theย built-in light.
Document & Record

Record the pre-clean inspect & benchmark results into DPF Cleaning Record software.

Blow (De-Ash)

Remove as much loose material as possible from the filter before baking.

CLEAN

Bake
  • Loadย the filters into the oven.
  • Set the filter cycle based on the filters being cleaned.
  • Using the redesignedย new touchscreenย user interface.
  • The baking cycle usually runsย overnight.
Cool
  • Carefully remove theย hot filtersย from the oven.
  • Place the filters on theย Cool-Down Cart.
  • Accelerated the cooling process safely.
Blow
  • Usesย high-velocity, heated air.
  • Most filters dry inย 20 minutes.
  • Anย adapterย kit is available for many odd and irregularly shaped filters.
  • Exclusiveย to the Aqueous package.

POST-CLEAN

Inspect & Benchmark
  • Wire/Pin testย for plugged cells if needed.
  • Measure & compareย theย airflowย of the cleaned filter to determine effectiveness.
  • Measure & compareย the cleaned filterย weightย to see how much soot was removed.
Document & Record

Record post-clean inspect & benchmark results into DPF Cleaning Record software.

How long does DPF cleaning takeโ€‹?

The Thermal cleaning process usually is about a day. The baking cycle is often completed overnight and then it takes a few hours for the filters to cool down.

How much does DPF cleaning cost?

At Diesel Emissions Specialists, we charge $350 per DPF filter cleaning, $500 per DPF & DOC combo cleaning, $350 per SCR cleaning, $1,200 per Freightliner One Box cleaning (including the 2 DPF filters).
