5. Diesel Cars and DPF Filter Cleaning
In modern diesel cars it´s always advisable to make the DPF filter diagnosis before the treatment,especially
when the car drives only in towns and it is not possible to make the normal regeneration of the DPF. If the
diesel car has already a problem with the diesel particulate filter (DPF), then it´s likely that the problem could
get more severe with our treatment due to soot coming out of the engine and exhaust system.
exhaust gases. A layer of soot then starts forming on the walls of the filter. In long tern this layer of soot will
influence the performance of the engine being necessary to start the regeneration process on the second step.
Second step:When we have the right conditions, the filter force the temperature of the exhaust gases to rise
enough to burn the soot layers. The regeneration process will not work properly when temperatures are low
in winter (for example in Northern Europe) or when the cars only drive in towns or small distances.
When cleaning diesel cars we recommend also the useof the special DXA250 additive
produced for our machines. This additive allow the regeneration of diesel particulate
filters using our engine carbon cleaning machines without removing the DPF. This
additive lowers the ignition temperature of the soot collected in the DPF, optimizing
the regeneration process. The increase ofexhaust gases temperature provided by the
combustion of hydrogen during the treatment will allow the right conditions for the
regeneration of the FAP.
This additive can be used as a preventive treatment or as a repair treatment if the DPF
filter is very clogged. Preventive treatment should take place in countries where
temperatures are low in winter (for example in Northern Europe) or when the cars only
run in cities and small distances.
Dosage: We add a bottle (250 ml) of the additive in 20 liters of fuel just before starting
the treatment with our machine.
Duration:2 hours
Engine revolutions during treatment: Engine at 1000 rpm for one and after one hour at 2500 rpm.
If the DPF is clogged then we should clean it using our
engine carbon cleaning machine. We the lines below we
will explain how do this operation.
The main function of the DPFfilter is to reduce the
emissions of fine particles (soot) contained in the exhaust
gases. The DPF works in two stages, first he collects the
particles and after it eliminates them:
First step: The filter traps the particles in suspension in the
