FAP Regeneration: Everything You Need To Know
Content
The Diesel Particulate Filter (DPF) limits the emission of pollutants and is located in the exhaust line. When used on a daily basis while traveling, it clogs up over time and its effectiveness decreases. That is why it is necessary to continue the DPF regeneration.
💨 What does DPF regeneration include?
The combustion of the air-fuel mixture in the engine will result in soot particles to be burned, then collected and filtered FAP. Therefore, heated to a high temperature, the DPF can burn all particles and allows exhaust release less polluting gases.
When we talk about DPF regeneration, it means emptying, cleaning and emptying process particulate filter. DPF regeneration can be done in 4 different ways:
- Passive regeneration : This happens naturally when you are driving at high speed with the engine. Since the DPF needs heating to remove all impurities, it recovers when you drive about fifty kilometers at over 110 km / h.
- Active regeneration : This process is built into your vehicle and starts automatically when the level of collected particles becomes too high.
- Regeneration with additive : This consists of pouring the additive into the fuel tank and then traveling ten kilometers with the engine mounted on supports to clean the DPF.
- Regeneration with descaling : This method should be done by a professional using special tools. It allows you to thoroughly clean the engine and exhaust system, removing all carbon deposits.
⚠️ What are the symptoms of blocked DPF?
If your particulate filter is clogged, it will quickly take a toll on your vehicle. Thus, you can detect clogging if you encounter the following situations:
- Black smoke comes out of your pot exhaust : particles are no longer removed correctly due to clogged filter;
- Your engine stalls more and more : The engine seems to be muffled and difficult to start.
- Your fuel consumption will increase : the engine overheats to dissolve the particles, it consumes much more diesel than usual;
- Loss of engine power is felt : The engine will not be able to maintain speed at high revs, especially when the accelerator pedal is depressed.
👨🔧 How to regenerate DPF?
If you would like to regenerate your vehicle's particulate filter yourself, you can do it in two different ways. It should be noted that if the first so-called passive method does not work, it will be necessary to switch to the second method with additive... To restore the particulate filter, follow these steps:
- Regenerate your DPF while driving : This method is most effective when done regularly. Indeed, it is necessary to wait until your engine has warmed up after driving about twenty kilometers at a speed of over 50 km / h.From now on, you can choose a lane like a highway to be able to drive at 110 km / h for about twenty minutes. ... This will prevent your DPF from clogging up.
- Insert Additive : This action can be prophylactic or curative. An additive will need to be added to the fuel. Then you will have to drive at least 10 kilometers, forcing the engine to work in the towers. This will facilitate the DPF regeneration cycle.
If you go to a professional and the DPF is very messy, it will perform descaling... This intervention will also clean all air ducts and components of the engine and exhaust system.
However, if the DPF is completely blocked, he will have to replace it because he will not be able to recover it.
💸 What is the cost of regenerating a particulate filter?
The cost of DPF regeneration can vary from one time to two times, depending on his health condition. For example, classic regeneration is paid on average 90€, details and work are included. But if your DPF needs deep cleaning because it is almost clogged, the amount can go up to 350€.
Regenerating DPF is important for keeping your diesel engine healthy and performing well over the long term. Since the price of such intervention is very different, do not hesitate to use our garage comparator to find the one closest to you and carry out this operation on your car at the best price!
