M Wilson Motor Repairs offers a complete range of DPF services to motorists in St Albans, Hatfield, Welwyn Garden City and Hertfordshire. From turbo cleaning and DPF cleaning, to DPF regeneration, we keep diesel particulate filters operating at optimal levels. The DPF is a feature on diesel models and one that has been in use for two decades. The filter captures and stores exhaust soot to reduce emissions. A DPF only has a finite capacity so, to successfully regenerate, it needs to burn this soot off.
Without ongoing maintenance, the DPF becomes inefficient and, eventually, has a negative impact on engines and performance. Below, we take a closer look at the more important elements of DPF cleaning and regeneration services, as well as turbo cleans.
M Wilson Motor Repairs has an extensive range of automotive services available in St Albans and the surrounding areas, including Volvo servicing and car repairs on all popular makes and models, and Class IV MOT testing.
The key to DPF cleaning sits firmly with the regeneration process. A DPF regenerates in two ways:
DPF regen occurs when cars run at speed on long stretches of motorways or roads. These journeys increase exhaust temperatures to the required levels for soot burning. We advise diesel owners in St Albans, Hatfield and Welwyn Garden City to drive at sustained speeds for 30 to 50 minutes, creating ideal conditions for passive regeneration.
Short journeys rarely allow for sustained speeds and passive DPF regen. Because of this, active regeneration occurs. This involves the automatic injection of extra fuel when a DPF reaches a predetermined soot limit of around 45%. By raising the temperature of the exhaust, DPF cleaning takes place to burn off soot.
The regeneration process might not reach a full conclusion over a shorter journey, leaving the DPF partially blocked and warning lights illuminated.
Inadequate DPF regeneration is the main cause of diesel particulate filter issues.
