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.
