Astonishing Visuals Watch How DPF Regeneration Comes to Life in this MindBlowing Animation

By “recent, ” we mean 2007; diesel trucks from that model year and onward are “blessed” with a diesel particulate filter (DPF). These filters grab soot from your exhaust before it blows out into the environment. It’s a wall-flow filter usually made of cordierite, silicon carbide, or a ceramic monolith.

As the exhaust gasses pass through the filter, it captures somewhere between 85%-100% of diesel particulate matter (DPM). The filter removes a

DPF maintenance is relatively straightforward. A warning light usually shows up, indicating it is time to literally burn out the accumulated soot. In addition to regeneration, periodic DPF cleaning is required, too.

Diesel Particulate Filters Dpf

DPF regen happens when the trapped particulates heat up enough to combust and turn to ash. The built-up soot is then removed as gaseous carbon dioxide.

Passive regeneration happens automatically. Once the exhaust temperature reaches a certain point—we like to use the example of driving at high speeds—the built-up matter in the DPF turns to ash.

No active changes in engine operation are involved. As another example, diesel trucks that frequently climb hills should have no problem passively regenerating their DPF. Under these conditions, soot burns off as fast as it is generated!

Active regeneration happens when changes in engine operation are required to get the Engine Control Module (ECM) to burn out and/or some catalyst is introduced. This is common among trucks with a lighter duty cycle, because soot accumulates while idling or going slowly through traffic.

One active regeneration method involves the ECM tweaking engine parameters to increase the exhaust temperature. The ECM then switches on an extra fuel injector that shoots fuel into the exhaust stream. This fuel reacts with a catalyst and burns the built up soot out of the DPF.

If active regen requirements aren’t met or soot levels rise to a certain point, you may need to perform a forced regeneration. You’ll need a diagnostic tool for this. You’ll also want to get to work on it sooner rather than later, as continuing to operate the vehicle at this stage can ruin the DPF and cause other damage.

Causes Of Dpf Failure And How To Perform A 'regeneration'

But even a forced regen will not work if soot levels have overwhelmed the DPF. At about 85% soot capacity and above, the DPF will need to be either removed and cleaned or replaced.

You’ll need to clean the DPF every 150, 000 to 300, 000 miles to remove accumulated ash. This ash buildup is not necessarily related to regens, but is most often due to sulfated ash in the engine oil. You’ll also need to clean the filter if a fuel injector or turbo problem causes contamination with engine oil or non-combusted diesel. This contamination causes unacceptable back pressure.

Cleaning methods include air blasting, the use of deionized water, and a vacuum-like system. You’ll need to clean very, very carefully so as not to damage the filter, and removing particulate matter must be handled with the proper equipment and care so technicians are not exposed to its extremely fine contaminants.

You guessed it: the diesel particulate filter is one more thing that must be tracked and maintained on a heavy-duty truck. Making sure the truck is on a regular preventive maintenance program will help ensure the long life of the DPF, as will regularly replacing air filters and fuel filters. While expensive for truck owners, the removal of diesel particulate matter before it blows into our breathing air certainly has its benefits, and using the correct type of oil for the engine will also help prevent unnecessary wear and the problems that can come with it.

Fortunately, makes it easy to maintain your or your customers’ DPFs—but that’s not all. It also helps you track preventive maintenance, streamline your shop’s operations, and run a more profitable business. Schedule a free demo of our shop management software.

I’ve used half a tank of fuel so far after adding the product and am now getting uneven running. I did 2 runs at 2500/3000 revs on mostly A roads 40 mile round trip’s. Plus some short runs without the high revs. The Jury is out at the moment. Maybe some carbon has dislodged and needs clearing. Back pressure could be a contributing factor. Not a lot of smoke from the exhaust. Perhaps it needs cleaning through the sensor straight into the filter.? I do about 1100 miles a week so shouldn’t really be in this situation. Regular petrol cars in the future.!!

My wife's car had dpf warning lights on for about a month, I tried other cleaners but no good. Then I saw this and thought I would pay the extra money and hope it works. Two days after putting it in the tank and taking it for a run all warning lights are gone and the car is running a lot better 😃. I would recommend it to anyone having trouble with a dpf fault. Very happy customer.

Used this product on my zafira which was choked up with loss of power. Put this in the tank and cured the problem. Totally amazing stuff. Worth spending the extra money.

Last year, on my visits to various customers, I made enquiries about the general demand for Diesel Particulate Filters. I was staggered at the lack of DPF knowledge, especially the procedure regarding installation, encountering answers such as: “We regard it as a main dealer product” or: “We need specialist diagnostic tools”.

EEC subsequently decided to eliminate one of these major objections. We contacted a diagnostic tool company and discussed the opportunity of becoming our partners in a venture to create a specialised hand-held DPF diagnostic tool.

Understanding Dpf Maintenance

After many months of hard work collating all of the data required to deliver an easy-touse, hand-held solution, the EEC DPF Reset Tool was born.
