What is DPF?
A DPF is a device designed and integrated into the Diesel Engine exhaust system to trap and remove DieParticulate Matter from the exhaust gasses of the diesel engine. Much like the Catalytic Converter on conventional petrol engines, the works to remove harmful toxins and lower the emissions of your diesel engine making it more environmentally friendly.
The aim is to remove 80% in the average diesel particulate (matter) emissions and although a great concept, it brings about a whole new line of problems. We are taking calls constantly from anxious customers and garages across the country when their DPF light is illuminated on the dash, indicating that there is at least a partial blockage in the DPF system.
If the majority of journeys are city based, short or stop/start, or a combination of them all, then the filter will not be able to regenerate, the honeycomb will block with soot and a DPF warning light will illuminate on the dash board, in some cases the car may enter Limp Mode to protect both the DPF and the engine from damage.
But the story does not end there; the result of the regeneration is ash, over a period of time the ash resulting from correct regeneration accumulates inside the filter, a correctly operating filter will eventually block with ash, something usually between 70,000 and 100,000 miles.
The good news is this can be cleaned out with our process of blasting the channels with air to remove the build up of ash followed thermal treatment for any soot which has not been regenerated in the filter.
Regular filter cleaning will help
- Reduce engine emissions
- Reduce ash build up in the filter
- Extend the life of the Diesel Particulate Filter
- Keep vehicle running costs down
- Improve overall fuel economy
- Maintain an efficient engine
Don't Replace DPF!!!
Unless to original grey DPF, DPF with white ceramic can't be regenerated properly so it will be blocked within few months and damage your turbo!!!
DPF Cleaning Liquids or on-board treatment will help you but only for short time. Because it burns black soots but particulate matter from unburnt diesel can't be removed by this type of cleaning.
