MAN Diesel Particulate Filter (DPF) Technical Parameters
Parámetro
Valor típico / Rango
Descripción
Modelos aplicables
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.
Norma de emisiones
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.
Longitud
~600-1200 mm
Length varies depending on engine size, exhaust configuration, and DPF type.
Diámetro
~200-400 mm
Outer diameter depends on model and soot storage requirements.
Peso
12-35 kg
Approximate weight varies by model and housing type.
Densidad celular (CPSI)
200 / 300 / 400 / 600
Number of cells per square inch; higher CPSI increases filtration efficiency but may raise backpressure.
Contrapresión (limpio)
2-10 kPa
Pressure drop across a clean DPF; lower backpressure is better for engine efficiency.
Contrapresión (cargado)
Hasta 25 kPa
Maximum allowable backpressure; indicates soot accumulation and triggers regeneration.
Eficacia de filtración
≥ 95%
Removes 95% or more of particulate matter under normal operation.
Temperatura de funcionamiento
200-600 °C
Normal operating range for soot trapping and regeneration; may peak higher during active regeneration.
Tipo de regeneración
Pasivo y activo
La regeneración controlada por la ECU quema el hollín acumulado para restaurar el rendimiento del filtro.
Números de pieza OE
51.09101-7011, 51.09101-7007, 51.09101-7010…
Common OEM reference numbers for MAN DPFs.
Notas para los responsables de la toma de decisiones
Coincidencia de modelo y norma de emisiones: Ensure the DPF corresponds to the MAN model and the Euro emission standard.
Elección del material: Cordierite is widely used for standard applications; Silicon Carbide or Stainless Steel offers better thermal shock resistance for high-load, high-temperature environments.
Eficacia de filtración frente a contrapresión: Higher CPSI increases particle capture but may increase backpressure, affecting fuel economy and regeneration frequency.
Estrategias de regeneración: MAN DPFs typically support automatic regeneration based on temperature and backpressure readings to maintain engine performance and prolong filter life.
