Unfortunately, this ingeniously conceived idea is quite challenging to implement in practice, often leading to premature clogging and inevitable problems with the DPF.

Regeneration Process

The standard regeneration process, designed by vehicle developers, can occur in two main scenarios:
1. Soot combustion by exhaust gases artificially heated to 600-800°C.2. Incineration of residues at standard temperature using a special liquid.
The self-cleaning of the DPF can be initiated by the engine control unit upon receiving relevant data from temperature and differential pressure sensors. The exhaust system typically has two pairs of these sensors: one set before and one after the filter. However, in practice, several factors must align for regeneration to occur. In some cases, manual initiation of cleaning is possible, but it is also very complex. Importantly, the regeneration process is highly undesirable to interrupt.

Identifying Exhaust System Blockage

Here are the main symptoms of DPF problems:
● Decreased engine power and performance. The vehicle responds slower to acceleration, and maximum speed decreases.● Increased fuel consumption. A clogged filter leads to inefficient fuel combustion, prompting the engine control unit to burn more fuel to initiate regeneration.● Engine starting issues. Due to exhaust system contaminants, the engine struggles to “breathe” freely.● Unpleasant odors and increased smoke emission are also indicative of blockage.● Dashboard indicators. Check Engine messages signal DPF issues.

Removal or Cleaning – What to Choose

Since factory equipment for DPF cleaning doesn't always work effectively, and replacing it with a new original unit is costly while opting for cheap alternatives is unjustified due to their low quality, much diesel vehicle owners decide to remove the DPF. However, this is fundamentally incorrect.
Firstly, because the vehicle's exhaust system stops trapping harmful substances. Secondly, the car's electronics have to be reprogrammed to meet lower Euro standards, risking inspection problems mandatory for some categories of commercial vehicles. Difficulties may also arise when crossing EU borders or other countries where emissions standards are closely monitored.
Repair shops specializing in diesel vehicle maintenance are well aware of these issues. Therefore, they often offer a service called DPF cleaning. This procedure is usually carried out using chemicals: a special solution is poured into the filter cells, left to soak, and then drained. In many cases, DPF removal from the vehicle is not even necessary.
However, the chemicals used are highly active, which raises concerns about the environmental impact and the health risks to personnel conducting the work. Proper disposal of the toxic waste from the cleaning process becomes a major headache for service stations.

MS900 as a Solution to DPF Problems

An alternative is the MS900 stand for cleaning DPFs. It cleans the soot without using chemicals; the only substances involved in the process are warm water and air. Nevertheless, chemicals can also be applied if necessary, for instance, if there are residues of motor oil in the filter cells, it is better to wash them out beforehand.
The soot and other harmful substances washed out of the filter are captured by a special device (hydrocyclone) and can be easily removed after the process is complete. The water passes through three stages of filtration: coarse, medium, and fine, circulates in a closed circuit, and can be used for several washes.
Moreover, our DPF cleaning equipment has other significant advantages:
1. The dimensions of the MS900 allow washing filters of both passenger and commercial vehicles.2. The washing process is automatic, requiring no constant human involvement.3. Diagnostic capability with before and after comparison of results.4. Drying function, absent in counterparts from other manufacturers.5. The particulate filter cleaning system of the MS900 stand allows washing and drying of passenger car filters at the same time if necessary.
However, the main advantage of this unique technology is that after cleaning, the throughput capacity of the DPF becomes practically equivalent to a new unit. This can be verified through diagnostics with the option to print the results using a printer connected via Bluetooth. The MS900 stand, the best equipment in its segment for DPF cleaning, preserves the environment, saves money, and allows maintaining factory parameters. With its help, the DPF's service life increases significantly, almost matching the vehicle's lifespan.
