DPFフィルターの清掃方法

5月 29, 2025

At the very base level and in the most technical words, the sequestering of particulate matter (PM) in the diesel particulate filter (DPF) is the most important process in the emissions reduction system. But, if DPF gets older, it can get clogged by the ash and then the car may use more fuel, become less powerful and, in some extreme cases, experience serious damages. The thing is, knowing how to clean the DPF filter the right way is a must if you want your engine to continue functioning for a long time and at the same time not be too costly.

YongYong emphasizes sensitive environmental issues and productive and powerful engines by availing itself of our exclusive collection of the Cummins Clamp Gasket Kit, MAN DPF Gasket, and ボルボクランプガスケットキット, which are the best solutions for supporting and guaranteeing a seal after cleaning or replacing the DPF system.

Why DPF Cleaning Is Necessary

The DPF is designed to capture and store exhaust soot. However, after thousands of miles, the filter reaches a saturation point. If not properly cleaned, it can become clogged, triggering warning lights and forcing the vehicle into “limp mode.” This restricts engine power and can lead to expensive repairs.

There are two main methods for DPF cleaning:

  1. Passive Regeneration – This occurs naturally when the vehicle is driven at highway speeds, allowing the exhaust to reach temperatures high enough to burn off soot.
  2. Active Regeneration and Manual Cleaning – In cases of severe blockage, professional cleaning or even removal is required.

How to Clean a DPF Filter Properly

Step 1: Diagnosis
Use a diagnostic tool to check soot levels and assess whether regeneration is working. If the filter is too blocked, cleaning is necessary.

Step 2: Removal
Safely remove the DPF filter from the vehicle. This process may also require detaching clamps and gaskets. That’s where Tianjin YongYong’s durable Volvo Clamp Gasket Kit and MAN DPFガスケット come into play. Using high-quality sealing kits ensures there are no leaks once the system is reassembled.

Step 3: Cleaning
You can either use a professional DPF cleaning machine or apply a cleaning solution. The process involves:

  • High-pressure air to blow out loose soot
  • A heat cycle or solvent flush to remove stubborn deposits

Step 4: Drying and Inspection
After cleaning, allow the filter to dry completely. Inspect for cracks or damage. Replace gaskets and clamps if necessary using a trusted カミンズクランプガスケットキット to ensure long-term reliability.

Step 5: Reinstallation and Testing
Reinstall the DPF filter using the appropriate gasket kits. After securing all connections, reset the DPF status using a diagnostic tool and run the engine to confirm normal operation.

Tips to Extend DPF Life

  • Use low-ash engine oil
  • Avoid short trips when possible
  • Drive at highway speeds regularly to promote passive regeneration
  • Replace gaskets and clamps during every DPF service with OEM-quality parts such as those offered by 天津永勇
