Regeneration Is Not An Answer.
One way a DPF maintains the accumulated soot and PM requires extreme temperatures (at least 600 Celsius) at which point the soot and ash will burn away. These get turned into smaller particles and can now pass through. This process is called ‘Regeneration’ and is fundamental to maintaining a clean a DPF in between routine cleanings. There are three different types of regeneration, active, passive, and forced.
Won’t Reach High Enough Temperatures.
Regeneration is a natural process that occurs when driving at high speeds like on the freeway. If it doesn’t reach regeneration on it’s own, soot won’t burn away because your engine won’t reach the temperatures it needs to be able to reach a level of combustion of all of the larger particles.
Invest in Maintaining Your Diesel.
If you live in a more urban area like LA county of Southern California in general, you are likely familiar with being unable to drive at high speeds for long distances due to a multitude of reasons. These conditions are even more likely to add to the necessity of getting and understanding DPF maintenance.
You Can’t Rely on Regeneration to Clean Your DPF.
This is a mistake that many newer diesel car owners can make because of their DPF warning lights. Some have regeneration buttons that have been manufactured to meet standards, leading people to believe they don’t need to take their DPF in to be cleaned properly.
Improve Performance & Emissions Compliance.
Yes, regeneration is healthy, but your DPF will need a regular cleaning to get larger particles out no matter what. Without proper cleaning of your DPF every 25,000 miles or so, your DPF lifespan and more importantly your vehicle’s performance and emissions will be in compliance with CARB, EPA, and the CAA.
This is the only way to go about checking on your diesel engine emissions and keeping your truck or fleets in compliance with expensive regulatory enforcement. A DPF cleaned on a average basis will extend your overall performance and lifespan of your truck and keep your business going.
Don’t Listen to Manufacturers.
Unfortunately, many have been led to believe that all they need to do to maintain their DPFs and keep them clean is by hitting the regeneration button. You can push the regeneration button in your car, but what left in your filter will still be there. Many people believe this cleans their DPF, however, this remaining PM creates pressure that will eventually lead to: DPF failure EGR valve failure emissions systems failure,most importantly engine damage.
