Cummins DPF
We are a professional supplier of Diesel Particulate Filters (DPF), dedicated to meeting the stringent Euro 5, Euro 6, EPA07, and EPA10 emission standards. Since 2014, we have collaborated with leading global vehicle manufacturers, ensuring high-quality, reliable, and cost-effective solutions.
Cummins Diesel Particulate Filter (DPF) Technical Parameters
| Parameter | Typical Value / Range | Description |
|---|---|---|
| Applicable Models | Cummins ISB, ISL, ISX, QSX, X15 | Compatible with a range of Cummins engines used in trucks, buses, and industrial machinery. |
| Emission Standard | EPA 07 / EPA 10 / Euro 4 / Euro 5 / Euro 6 | Designed to meet both US and European emission standards depending on engine and application. |
| Material | Cordierite / Silicon Carbide / Stainless Steel | Durable materials optimized for high thermal resistance and efficient particulate filtration. |
| Length | ~400–1200 mm | Varies based on engine displacement and exhaust layout. |
| Diameter | ~200–400 mm | Outer diameter depends on model and soot storage requirement. |
| Weight | 10–35 kg | Depends on substrate type, housing, and engine compatibility. |
| Cell Density (CPSI) | 200 / 300 / 400 / 600 | Higher CPSI improves filtration efficiency but may increase backpressure slightly. |
| Backpressure (Clean) | 2–10 kPa | Pressure drop across a clean DPF; critical for engine efficiency. |
| Backpressure (Loaded) | Up to 25 kPa | Indicates soot accumulation; triggers regeneration. |
| Filtration Efficiency | ≥ 95% | Effectively captures 95% or more of particulate matter under normal operation. |
| Operating Temperature Range | 200–600 °C | Normal operating range; can reach higher during active regeneration. |
| Regeneration Type | Passive & Active | ECU-controlled regeneration burns accumulated soot to restore filter efficiency. |
| OE Part Numbers | 4955972, 5283784, 5297921… | Common OEM reference numbers for Cummins DPFs. |
Key Selection Guidelines
-
Engine & Emission Standard Matching: Verify the DPF fits the specific Cummins engine model and emission regulation (EPA or Euro standard).
-
Material Choice: Cordierite is suitable for standard operating conditions; Silicon Carbide or Stainless Steel substrates are recommended for high-load, high-temperature applications.
-
Filtration Efficiency vs. Backpressure: Higher CPSI increases particulate matter capture but can raise backpressure, affecting fuel economy and regeneration frequency.
-
Regeneration Strategies: Automatic or ECU-controlled regeneration ensures consistent DPF performance and prolongs service life.
