MAN DPF

MAN Diesel Particulate Filter (DPF) Technical Parameters

パラメータ
代表値 / レンジ
説明

対象モデル
MAN TGA, TGS, TGX, ライオンズシティ, ライオンズコーチ
Fits a variety of MAN truck and bus models across different years and engine sizes.

排出基準
ユーロ4／ユーロ5／ユーロ6
Designed to meet corresponding European emission regulations depending on the vehicle model.

素材
Cordierite / Silicon Carbide / Stainless Steel substrate
High thermal resistance and filtration efficiency for long-term operation.

長さ
~600-1200 mm
Length varies depending on engine size, exhaust configuration, and DPF type.

直径
~200-400 mm
Outer diameter depends on model and soot storage requirements.

重量
12～35キロ
Approximate weight varies by model and housing type.

細胞密度（CPSI）
200 / 300 / 400 / 600
Number of cells per square inch; higher CPSI increases filtration efficiency but may raise backpressure.

背圧（クリーン）
2-10 kPa
Pressure drop across a clean DPF; lower backpressure is better for engine efficiency.

背圧（負荷時）
最大25kPa
Maximum allowable backpressure; indicates soot accumulation and triggers regeneration.

ろ過効率
≥ 95%
Removes 95% or more of particulate matter under normal operation.

動作温度範囲
200-600 °C
Normal operating range for soot trapping and regeneration; may peak higher during active regeneration.

再生タイプ
パッシブ＆アクティブ
ECU制御による再生が蓄積した煤を燃焼させ、フィルター性能を回復させる。

OEパーツ番号
51.09101-7011, 51.09101-7007, 51.09101-7010…
Common OEM reference numbers for MAN DPFs.

意思決定者のための注意事項

モデル＆エミッション・スタンダードのマッチング： Ensure the DPF corresponds to the MAN model and the Euro emission standard.

素材の選択： Cordierite is widely used for standard applications; Silicon Carbide or Stainless Steel offers better thermal shock resistance for high-load, high-temperature environments.

ろ過効率対背圧： Higher CPSI increases particle capture but may increase backpressure, affecting fuel economy and regeneration frequency.

再生戦略： MAN DPFs typically support automatic regeneration based on temperature and backpressure readings to maintain engine performance and prolong filter life.
