How to Clean Your HJS Diesel Particulate Filter (DPF)
With Water for Maximum Performance
Keeping your HJS Diesel Particulate Filter (DPF) clean is essential for maintaining optimal engine performance, improving fuel efficiency, and ensuring compliance with emission standards. Unlike traditional ceramic filters that require oven baking after just 8 hours of use, our DPF systems offer a far more convenient solution: clean your HJS Diesel Particulate Filter with water every 250–500 operating hours.
Step-by-Step Guide: How to Clean Your HJS Diesel Particulate Filter with Water
Cleaning your HJS Emission Technology DPF is a simple and effective process that requires only a high-pressure washer (hot or cold water) and no chemical additives.
Prepare the Cleaning Area
Work in a designated wash area equipped with an oil separator to safely capture residue and protect the environment.
Handle with Care
Ensure the filter is handled gently throughout the process to avoid damage to its internal components.
High-Pressure Cleaning
Maintain a minimum distance of 15 cm between the pressure washer nozzle and the filter. Continue spraying until the water exiting the DPF is clear, indicating all particulate residue has been removed.
Dry the Filter
Let the filter air dry completely or use compressed air to speed up the process. A fully dry DPF is essential before reinstallation.
Why Routine HJS DPF Cleaning Matters
Neglecting DPF maintenance can lead to:
- Loss of engine power
- Increased fuel consumption
- Poor throttle response
- Costly repairs or replacements
If your HJS Electronic Control Unit (ECU) displays a red warning light, it’s a clear sign your DPF needs immediate attention.
Key Signs You Need to Clean your HJS Diesel Particulate Filter:
- Persistent ECU warning lights
- Elevated exhaust system back pressure
- Reduced engine power output
- Repeated failed regeneration cycles
Top Benefits of Cleaning Your HJS Diesel Particulate Filter
Extended Engine Life
A clean DPF effectively traps and processes harmful particulates during regeneration. When soot accumulates and hardens, it blocks the system, increasing back pressure and engine wear. Regular cleaning prevents these issues and keeps your engine in better shape for longer.
Better Fuel Economy
A blocked DPF forces your engine to work harder, consuming more fuel. Routine maintenance ensures your engine operates at peak efficiency, reducing operating costs and emissions.
Maximum Filter Efficiency
Soot and ash buildup can reduce your DPF’s ability to perform, eventually leading to irreversible damage. Regular cleaning helps maintain consistent filtration performance and avoids the need for expensive replacements.
