A diesel DPF, also referred to as a particulate filter or trap, is designed to catch particulate matter and keep it from being emitted into the atmosphere. The diesel DPF is installed within the flow path of exhaust fumes where it collects the particulate matter and stores it. The particulate matter is eliminated when it is cleaned through filter regeneration. Regeneration times vary from filter to filter so you must check with your diesel DPF manufacturer’s guide for more information.
Diesel DPF – Installation Information
Purchasing a diesel DPF is an important decision and there are many things to consider.
1.) What diesel DPF units are verified for your fleet vehicle?
- Do you need an active or a passive filter?
- What is the duty cycle your fleet currently runs?
- Is it possible that the duty cycle will change in the future?
2.) Where can the diesel DPF be installed?
- How much space is available on the vehicle?
- Is there enough space to safely add a DPF unit?
- If not, is there something that can be removed, like a tool box?
3.) Does your vehicle have special equipment or working requirements?
4.) When was the last time a maintenance was performed on the vehicle?
- Have you performed an opacity test on the vehicle within the last month?
- Was the opacity test clean?
The answer to these questions can help you decide which filter is right for your fleet.
Diesel DPF – Global DPF
The Global DPF is an active filter, so it can be used on a variety of duty cycles giving you greater flexibility. Regeneration of the filter happens with the push of a button, so there is no need to plug it in or introduce an outside fuel source. The durable metal-mesh filter design is able to expand and contract quickly, without cracking, allowing for regeneration times of 10 minutes or less under normal working conditions.

Diesel is a type of fossil fuel which contains long carbon chains. These long chains, when burnt, break into smaller particles. This raises the question of getting rid of these smaller chains. A diesel DPF is a unique gadget which is becoming increasingly common. The reason behind it is that it blocks the aforementioned smaller chains and un-burnt particles from going into the atmosphere. Another important reason is that this is receiving backing from higher authorities because of the swelling concern to prevent pollution. Most governments have also passed standards commonly known as the “Euro 5” standard to which everyone has to comply.
Diesel DPF – How does it Work?
A diesel DPF needs to be programmed in such a way that it is able to convert the byproducts into harmless gases. This calls for a catalytic chamber which needs to be installed next to the engine. What the catalyst does is that it speeds up the combustion process. The other benefit of this chamber is that it will allow the candidate to drive slowly and the conversion process will continue at lower speeds. Also, this can facilitate the passive regeneration process to commence which is easier and cheaper than active regeneration. Active regeneration compels the candidate to install some other devices and gadgets to start the process.
Some diesel DPF manufacturers can also use different methods. This is because sometimes there is little space left near the engine to install the catalytic chamber. The most common method used is to add certain chemicals to the fuel which will lower combustion temperatures of the chains under scrutiny. The process of mixing these additives is to store the chemicals in a separate container and add them whenever refueling is done. This is a cheap method because a very low quantity of additives is required to enhance the incineration process. Generally, a liter of additive is enough for about three thousand liters of fuel injected into the engine.
Although the diesel DPF filter works efficiently most of the times, indications have been given that these systems are unable to perform in their characteristic way. This is a problem usually noted in cars with a high sixth gear. This is because the RPM of the engine inclines to be too low to generate a high enough temperature to spark the process. Driving at a high RPM can solve this problem. A good way to do it will be to drive harder at lower gears and subsequently increase the RPM.
