DPF – an abbreviation many car owners shudder to hear from time to time, but what does DPF stand for?
A Diesel Particulate Filter (DPF) is a vital component to many modern Diesel fueled motors around the world. It’s been compulsory to fit them to diesel vehicles in the UK since 2008. The aim is to reduce exhaust particulates by at least 80% – the main particulates being reduced are sulphated ash, phosphorus and sulphur. Located within the exhaust system, a DPF captures small soot particles, preventing them from being expelled into the atmosphere. As with any filter, it’s a must that the filter is emptied and cleaned periodically. This is done automatically, by burning the particulates in a process called regeneration.
DPF regeneration can take 20 to 40 minutes of driving and in that time the fuel and gas will pass the Diesel Oxidation Catalyst (DOC) creating temperatures high enough to burn the accumulated soot.
What does this mean for your shorter journeys? This is where we would recommend a DPF cleaner, to help DPF regeneration occur sooner at a lower temperature.
