Over the years I must have dealt with every DPF related issue you could imagine, but still the majority of customers when I contact them say that the new DPF which has been fitted is faulty! After looking into the issue I would explain that the problem was not the DPF but, more often than not, an injector, pressure sensor, temperature sensor or EGR valve issue.
Whichever component was at fault there would always be a knock on effect with an increase of Particulate Matter (PM) resulting in carbon coating injectors, inlet, exhaust, EGR valves, turbo etc. This results in an inability for the system to meet the required condition to activate the DPF regeneration process, ultimately ending in a blocked DPF.
Just over two years ago after looking at the cleaning products that are available we took the decision to produce our own additive to reduce the build-up of carbon on these components resulting in our 6 in 1 DPF solution.
This product cleans all of the relevant components and assists the regeneration process. Since the launch of 6 in 1 it has been a tremendous success supported by industry, private endorsements and recommendations.
Since entering this new product sector I have been staggered by the amount of inaccurate statements that are being made regarding what these fuel additives products claim they can do concerning their cleaning power of components including the DPF. For example; “When the vehicle gets to the correct temperature the vehicle does a DPF regen and burns the soot to ash to lower the contents inside the DPF.” Carbon-based soot is formed by the incomplete combustion of fuel. When burnt, this soot turns into carbon dioxide gas. It does not produce any ash!
PM is produced when diesel is combusted within the engine:
Particulate Matter (PM):
Another quote: Our fuel additive results show that the process removes both the soot and ash content inside the DPF.
To remove the ash from a DPF without removing the unit from the vehicle by dissolving it would require a strong acid based product which would require a warning on the container and instructions on how to safely handle the product using Personal Protective Equipment (PPE).
Other claims that have been made: Our fuel additive will clean EGR valves, turbo’s etc. Only additives containing Fuel Borne Catalyst (FBC) will remove carbon from all components post combustion. A fuel additive without an FBC would not survive the combustion process.
We recommend a concentrated additive like our 6 in 1 which is added every time refuelling is completed so that it is present all of the time. It contains a high tech FBC which is metallic but not iron.
