DPF Regeneration

Your car has a Diesel Particulate Filter or DPF in place which helps filter and traps harmful chemicals from the exhaust. Without a DPF, your vehicle tends to produce extremely noxious fumes which are dangerous for the environment. Like all filters, a DPF tends to clog up and need cleaning. It is what is known commonly as DPF regeneration.

DPF regeneration in Northampton is a pretty standard service which we at Jacksons Diesel Centre specialise in. We have expert technicians who are equally adept at the three fundamental types of DPF regeneration: active, passive and forced.

Why is DPF regeneration needed?

Soot eliminated during the combustion process primarily clogs DPF. However, there are other factors too: the exhaust rate, driving style, type of fuel used and even the DPF’s location. The most common reasons why DPF cleaning in Northampton is needed are mentioned below:

  1. Using low-ash engine oil: Using improper or low-grade engine oil often damages the DPF. Low-ash oils tend to build up enormous amounts of soot.
  2. Using 100% diesel Bio-fuel: Bio-fuel might be environment-friendly but very often; they do not burn as cleanly as regular diesel. That creates extra pressure on the DPF.
  3. Lots of short trips: Soot build-up is seen in cars which are primarily driven in cities. Experts at Jacksons Diesel Centre attribute this to the fact that the filter does not receive adequate time to clear the soot.
  4. Temperature matters: DPF regeneration relies on temperatures; for example, at 600°C, recovery is complete. However, driving for smaller timespans may not take the temperatures up to that mark, thus further degrading the DPF.

How can we help?

There are 3 main methods of DPF regeneration, and you will get them all at our Jacksons Diesel Centre. They are:

  1. Active regeneration: Perhaps the most common type, this system acts on a series of sensors which take the soot load off the vehicle. It adjusts the amount of fuel utilised accordingly. Any new car with an ECU requires an active regeneration every 400-600 miles, and it takes only around 10 minutes to complete.
  2. Passive regeneration: Some manufacturers prefer a passive method where the regeneration is mainly done via a pre-installed oxidising catalytic converter, located in the engine. The car is driven on a highway which provides ample time for the fuel to burn up to a high temperature. Note that passive regeneration does not work well for city commutes.
  3. Forced regeneration: ECUs control the regeneration process in this instance. If you notice your vehicle’s second stage DPF warning lights flashing on and off, it may be time for a DPF service. Bring your car as fast as possible to our service station.
