MAN Diesel Particulate Filter (DPF) Technical Parameters
Parameter
Typical Value / Range
Description
Applicable Models
MAN TGA, TGS, TGX, Lion’s City, Lion’s Coach
Fits a variety of MAN truck and bus models across different years and engine sizes.
Emission Standard
Euro 4 / Euro 5 / Euro 6
Designed to meet corresponding European emission regulations depending on the vehicle model.
Material
Cordierite / Silicon Carbide / Stainless Steel substrate
High thermal resistance and filtration efficiency for long-term operation.
Length
~600–1200 mm
Length varies depending on engine size, exhaust configuration, and DPF type.
Diameter
~200–400 mm
Outer diameter depends on model and soot storage requirements.
Weight
12–35 kg
Approximate weight varies by model and housing type.
Cell Density (CPSI)
200 / 300 / 400 / 600
Number of cells per square inch; higher CPSI increases filtration efficiency but may raise backpressure.
Backpressure (Clean)
2–10 kPa
Pressure drop across a clean DPF; lower backpressure is better for engine efficiency.
Backpressure (Loaded)
Up to 25 kPa
Maximum allowable backpressure; indicates soot accumulation and triggers regeneration.
Filtration Efficiency
≥ 95%
Removes 95% or more of particulate matter under normal operation.
Operating Temperature Range
200–600 °C
Normal operating range for soot trapping and regeneration; may peak higher during active regeneration.
Regeneration Type
Passive & Active
ECU-controlled regeneration burns accumulated soot to restore filter performance.
OE Part Numbers
51.09101-7011, 51.09101-7007, 51.09101-7010…
Common OEM reference numbers for MAN DPFs.
Notes for Decision-Makers
Model & Emission Standard Matching: Ensure the DPF corresponds to the MAN model and the Euro emission standard.
Material Choice: Cordierite is widely used for standard applications; Silicon Carbide or Stainless Steel offers better thermal shock resistance for high-load, high-temperature environments.
Filtration Efficiency vs. Backpressure: Higher CPSI increases particle capture but may increase backpressure, affecting fuel economy and regeneration frequency.
Regeneration Strategies: MAN DPFs typically support automatic regeneration based on temperature and backpressure readings to maintain engine performance and prolong filter life.
