Clean Your Diesel Particulate Filter (DPF) With Water
Cleaning your HJS Diesel Particulate Filter with water is a method that is easy and very effective. Cleaning intervals range from 250-500 operating hours. These industry leading intervals is a substantial improvement on a ceramic filter that must be baked in a specialised oven after 8 hours of use.
Let us have a closer look at the cleaning process of the DPF:
- The Diesel Particulate Filter can be cleaned using a commercially available high-pressured cleaner that uses hot or cold water. No cleaning additives are required.
- Ensure that you clean the filter in an area where residue can be collected in an oil separator to prevent damage to the environment.
- Always handle the filter carefully throughout the entire process.
- When using a high-pressure cleaner, always keep the minimum gap between the nozzle and the filter at 15 cm.
- Continue to clean the filter until there are no more residues left in the flushing water that is flowing out.
- After completing the cleaning process, let the filter dry in the air or blow dry it with compressed air.
Is it necessary to clean your DPF?
Yes, it is necessary to clean your DPF. Ignoring the DPF warning light on the HJS Electronic Control Unit (ECU) could result in power loss, reduced fuel economy, and poor throttle response. Cleaning your DPF at the prescribed intervals will ensure filter longevity.
Signs your DPF needs cleaning:
- When the red light on the ECU display appears.
- When the back pressure of the exhaust system is too high.
- When you feel there is a loss of power in your engine.
- Passive and active regeneration keeps failing.
What Makes DPF Cleaning Beneficial?
- Extended engine life
A functional DPF will capture toxic particles and transform them through a regeneration process. However, when unburned soot accumulates and hardens in the filter, it cannot complete its work completely. When the ash blocks exhaust and airflow, it creates back pressure, forcing the engine to work harder, and its components wear faster. Cleaning the DPF in time can avoid this problem.
- Improve fuel economy
Remember, a dirty DPF will not only wear down your engine but will also consume more fuel. Due to the accumulation of residues, your engine runs inefficiently, which will reduce the engine’s fuel efficiency. If you start to notice frequent pump bounces or a noticeable decrease in engine power and performance, you may need to perform a thorough cleaning.
- Better DPF performance
The accumulation of ash and soot will cause the DPF to become ineffective. Over time, this residue can cause irreparable damage to the DPF, which needs to be completely replaced.
Keep your new HJS DPF and old DPF soot-free by doing maintenance regularly. This will ensure that your DPF works efficiently and will prevent harm to the environment and the people around you!
