DPF Regeneration and Diesel Particulate Filters - Everything you need to know
Diesel Particulate Filters or DPF's as they are more commonly referred too are designed to reduce emissions, caused by diesel soot, by up to 80%. Great, in theory but not so great for the end user. Vehicle manufacturers are given emissions standards which they must meet upon production of a vehicle. The European Emissions Standards were first introduced in 1970 but didn't seriously effect the motoring world until 2008/2009 when the "Euro 5" standards were implemented. Although DPF's were being fitted pre 2008/2009, manufacturers were only doing this in anticipation of the Euro 5 being implemented. As mentioned, DPF's are designed to reduce emissions by up to 80% and are the only proven method of achieving this. However, they are what they say they are on the tin - a filter. As with any filters, DPF's become clogged. They catch or trap soot in the honeycomb filter design, therefore preventing them being released into the atmosphere. The unclogging process is what is called DPF Regeneration.
