Clean DPF and catalytic converter

Since 2009, which was when the Euro 5 emissions standard was introduced, every new diesel engine car has been fitted with a Diesel Particulate Filter (or DPF).  The DPF is self-cleaning and for a number of diesel car owners, the existence of a DPF and what it does, is of no consequence to them.

A DPF and/or catalytic converter collect the soot that is generated when diesel fuel is burnt, preventing pollution of the atmosphere from the potentially harmful soot particles. However, this soot in the DPF collects and builds up, and if not removed, it will block the exhaust causing engine inefficiencies and ultimately stopping the engine from functioning.

To prevent this from happening, the car needs to burn the soot at a higher temperature, to turn it into smaller ash particles which are then expelled from the exhaust.

Problems arise if a sufficiently high temperature to burn off the soot is not reached. Running a car at approximately 3000 rpm for 15 minutes or over is sufficient to get to the temperature required. If, however, a car is only taken on short, urban journeys, required ‘burn –off’ temperatures might not occur and the DPF will need to be cleaned.  

The ‘reverse- flush’ cleaning and regeneration service that we use at Darwen Diesels cleans a DPF to within 98% of its original ‘brand new’ condition, for a fraction of the cost of a brand new DPF, and with the peace of mind that the DPF is in a virtually ‘new’ state.
