What is DPF in Dorset

What is DPF?: Diesel Particulate Filters are products that are used to remove diesel soot from the exhaust of diesel engines. The filters are said to remove about 85 per cent of the soot and when paired with other equipment, they can remove 100 per cent of the soot. As of 2009, all new diesel powered vehicles are required to have DPF’s and car models of previous years will also have their exhaust pipes fitted with these filters. The aim is to have a minimal effect to the environment and thus protect it for future generations.

Soot Collection

The DPF’s trap soot that is in the exhaust and since a lot may be collected in the exhaust, it is best to empty it out regularly in order for it to be effective. Once collected, the soot is burnt at very high temperatures to leave an ash residue. This process is called regeneration and it may either be active or passive.

DPF Regeneration

DPF-equipped engines include a DPF-regeneration cycle in their operation – at this point fuel is injected into the exhaust phase which causes it to burn in the exhaust and DPF. This burns off the soot particles from the DPF but the metallic ash particles can not be removed. Over time the ash particles accumulate and will eventually block the DPF, requiring its replacement.

Passive Regeneration

Passive regeneration happens automatically on the road when the exhaust temperature becomes too hot. Active regeneration occurs when the set limit is reached. The temperature then may be raised by adjusting the fuel injection in order to start the regeneration process. If the journey is too short, then the regeneration process will not be completed and a warning light will signal that the filter needs to be emptied. Driving at speeds of over 40 mph, will start the regeneration process which will eventually clear the filters. If the motorist drives slowly, the soot will continue to build up and other dashboard lights will come on. When at 75 percent, the regeneration process will not occur even if the driver increases speed, they will have to go to a car dealer to have the process done.

DPF's are sometimes fitted with oxidising converters

DPF's are sometimes fitted with oxidising converters. They are placed close to the engine where heat will be generated and from there passive regeneration can occur. Sometimes, the engine is fully packed and there is no space for an additive. Some manufacturers use a different type of DPF that lowers the ignition temperature of the soot particles so it can be located further away from the engine. The additive is kept in a separate area and is automatically mixed with the gas when one fills up. Small quantities of the additive are used so a litre should clean out 2800 litres of fuel efficiently at 40 mph. What is DPF going to do eventually? It will reduce your carbon footprint and reduce harmful emissions to the environment, which is perfect for the environmentally conscious motorist.
