Diesel Particulate Filter Cleaning and Maintenance

Diesel Particulate Filter Cleaning and Maintenance

While this particular article is about Diesel Particulate Filter cleaning and maintenance, we thought it might be beneficial to review some basics about DPF and why cleaning is so critical.

What is a Diesel Particulate Filter (DPF)?

DPF is an acronym for Diesel Particulate Filter. A DPF works in conjunction with the oxidation catalyst and EGR valve to remove a majority of the NOx, particulate matter (think black, cough-inducing soot) and unburned hydrocarbons from burned diesel fuel. Soot is a natural byproduct from the combustion of diesel fuel. Inside the DPF is a porous honeycomb structure that catches the soot as it passes through. After the soot builds up over time, the onboard computer controls fuel injection to allow unburned fuel to enter the filter at measured intervals where it flares off and generates increased temperatures that incinerate the accumulated soot. The result: Soot is chopped by over 90-percent.

Maintaining Your Diesel Engine Vehicle is Critical

Accumulated soot creates back pressure that will eventually lead to increased regeneration down time, loss of horsepower, reduced fuel economy, filter damage and, ultimately, engine damage!

The improper care of your Diesel Particulate Filter could cause:

  • Engine malfunction or breakdown
  • DPF warranty to be voided
  • Hefty fines due to your diesel vehicle engine to be non-compliant with air pollution laws

What is the Recommended Interval for Diesel Particulate Filter Cleaning?

The interval for Diesel Particulate Filter cleaning varies between manufacturers specification, engine condition, duty cycle, and type of lube oil used in the engine. Most DPF retrofit manufacturers recommend cleaning the Diesel Particulate Filter once per year or about every 1000 hours of engine operation. In some cases, the required cleaning interval may be much shorter.

Enviromotive’s DPF Cleaning and Testing Systems Will Outperform the Competition.

  • EB9001 – Out-cleans other DPF Cleaning Systems using Dual Force: High pressure combined with suction.
  • EB9002 – Factory spec thermal regeneration allows for safe DPF cleaning.
  • EB9003 – Determines the amount of soot that is removed.
  • EB9004  Determines flow and identifies cracks or failures in the DPF substrate.

  1. Dear Sirs,
    Fornax manufacture industrial ovens for a wide range of applications to customers in Europe and Overseas. One of our customer groups uses Fornax Ovens to remove coatings from parts (paint, teflon etc.). Obviously, this is thermal cleaning at temperatures of 4-500 degrees C. We are interested in the cleaning at lower temperatures, for example cleaning of diesel filters. We wonder if you would be interested in a cooperation, and we kindly ask you for more information on your equipments as well as a prices. Is your equipment already on the market in Europe?
    We look forward to hearing from you and wish you a nice weekend.

  2. I don’t know much about auto and diesel stuff, so I had never heard of DPF before. I think it’s great that we can reduce soot by more than 90%. I bet it will keep going up too, because we’re always making improvements on emissions. Thanks for teaching me some new stuff today.
