MAN Diesel Particulate Filter (DPF) Technical Parameters
Paramètres
Valeur typique / Gamme
Description
Modèles applicables
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.
Norme d'émission
Euro 4 / Euro 5 / Euro 6
Designed to meet corresponding European emission regulations depending on the vehicle model.
Matériau
Cordierite / Silicon Carbide / Stainless Steel substrate
High thermal resistance and filtration efficiency for long-term operation.
Longueur
~600-1200 mm
Length varies depending on engine size, exhaust configuration, and DPF type.
Diamètre
~200-400 mm
Outer diameter depends on model and soot storage requirements.
Poids
12-35 kg
Approximate weight varies by model and housing type.
Densité cellulaire (CPSI)
200 / 300 / 400 / 600
Number of cells per square inch; higher CPSI increases filtration efficiency but may raise backpressure.
Contre-pression (propre)
2-10 kPa
Pressure drop across a clean DPF; lower backpressure is better for engine efficiency.
Contre-pression (en charge)
Jusqu'à 25 kPa
Maximum allowable backpressure; indicates soot accumulation and triggers regeneration.
Efficacité de la filtration
≥ 95%
Removes 95% or more of particulate matter under normal operation.
Plage de température de fonctionnement
200-600 °C
Normal operating range for soot trapping and regeneration; may peak higher during active regeneration.
Type de régénération
Passifs et actifs
La régénération contrôlée par l'ECU brûle la suie accumulée pour restaurer les performances du filtre.
Numéros de pièces OE
51.09101-7011, 51.09101-7007, 51.09101-7010…
Common OEM reference numbers for MAN DPFs.
Notes à l'attention des décideurs
Correspondance entre le modèle et la norme d'émission : Ensure the DPF corresponds to the MAN model and the Euro emission standard.
Choix des matériaux : Cordierite is widely used for standard applications; Silicon Carbide or Stainless Steel offers better thermal shock resistance for high-load, high-temperature environments.
Efficacité de la filtration en fonction de la contre-pression : Higher CPSI increases particle capture but may increase backpressure, affecting fuel economy and regeneration frequency.
Stratégies de régénération : MAN DPFs typically support automatic regeneration based on temperature and backpressure readings to maintain engine performance and prolong filter life.
