It’s common to get clogged filters. It just indicates that you should examine your diesel particulate filter right away to see if it requires to be cleaned or replaced. However, many individuals frequently enquire as to why they must routinely clear their DPFs. Here’s why: DPF cleaning will help cars not only prevent expensive & unforeseen problems but also improve fuel efficiency and prolong their lifespan.
Additionally, you should be aware that DPF wears out like any other auto part, so you need to get some professional DPF cleaning services, regardless of the vehicle’s condition. Your entire car functions as a system at all times, and you need these engines & components to make sure you’re driving safely. It is why investing the time & money necessary to ensure that you understand how to clean DPF filters properly is included in a good car.
Recognising the Importance of DPF Cleaning
A DPF filter’s main job is to capture soot particles & stop them from escaping into the atmosphere. These filters are made for burning off the trapped soot and transform it into innocuous gases through a method known as regeneration. Regeneration alone, but, isn’t usually enough to fully clean the filter. Ash residue accumulates over time and can’t be eliminated by smouldering alone. Because of this buildup, airflow is restricted, which lowers engine efficiency & may result in dashboard warning indications. To prolong its lifespan, restore functionality, and prevent expensive repairs, the DPF must be cleaned. A variety of cleaning techniques can be used, depending on the degree of obstruction and the vehicle’s usage.
Cleaning with Hydrodynamics
The cleaning technique involves using specialised equipment to generate a fluid operating jet that is aimed straight at the filter inside. It is necessary to use a cleaning agent, such as detergent. Its safety for the filter catalytic coating serves as one of its benefits. High efficacy, reaching up to 99.5% of its potential. It is one of the few that can effectively clean the filter pathways of all particles, including carbon deposits, ashes, soot, and cerium oxide.
Heat Treatment
Soot is cured in an induction boiler. Putting the filter core’s ceramic insert in the boiler for roughly twelve hours. You can be sure that the above procedure will eliminate and heal soot properly. But there might not be many drawbacks to using this. It can’t possibly entirely remove the residual particles like ashes. Additionally, because the filter ceramic insert is susceptible to abrupt temperature changes, there is a significant chance that it will be damaged.
Aqueous DPF Cleaning
Another excellent option is Aqueous DPF Cleaning, which can handle filters of a variety of shapes and sizes without losing their substrate and has an incredibly quick turnaround time. Trucks may resume driving the same day thanks to the non-destructive, water-based cleaning method, which effectively cleans in a few hours. Additionally, because it easily cleans and dries various or odd-shaped filters, it removes the demand to cut open filters with tapered inlets and/or outputs. It is also a multi-stage process.
Assessments and benchmarking are crucial for gauging the effectiveness of cleaning. The Filtertherm Aqueous machine, for instance, uses an automated, high-volume, low-pressure water flow to gently remove soot & ash from the DPF substrate after first releasing ash particles with a pre-soak surfactant stage. To reduce water consumption, the water is filtered & circulated.
Chemical Processing
The activity involves putting specific chemicals within the filter to break down soot. Carbon deposits are chemically treated with one getting ready, and subsequently flushed with another. A mechanic then starts the filter regeneration servicing operation by connecting the vehicle to the service computer.
Ultrasonic DPF Cleaning
There has also been considerable interest in ultrasonic DPF cleaning. The procedure uses high-frequency signals and sound waves to remove dirt particles while the filter is submerged. These waves create tiny bubbles that, when paired with specific tools and a cleaning solution, eliminate the ash and particle matter. It’s important to make sure the cleaning solution is consistent with the filter that is being cleaned, even though it’s usually mild and appropriate for different kinds of filters.
For instance, because of the materials (matting) employed in their manufacturing, certain retrofit filters shouldn’t become wet. The initial cost of this method is typically significant (to purchase a quality, comprehensive setup). Large-scale activities might be automated, but this frequently requires skilled setup, calibration, and maintenance.
Conclusion
Keeping a diesel vehicle’s performance and adherence to pollution regulations requires routinely cleaning the DPF filter. Different techniques can be used to meet various requirements and blockage levels, ranging from expert off-vehicle cleaning to passive and active regeneration. Both money and time can be saved by reducing the desire for frequent cleaning through scheduled upkeep and careful driving practices.
