DAF Diesel Particulate Filter (DPF) Technical Parameters
Parametro
Typical Value
Descrizione
Filter Diameter
190‑330 mm
Outer diameter of the DPF ceramic/metal substrate — actual size varies by model and engine configuration.
Filter Length
150‑305 mm
Length of the DPF substrate, related to soot storage capacity and backpressure characteristics.
Densità cellulare (CPSI)
200 / 300 / 400 / 600
Cells per square inch indicating filtration surface area — higher CPSI increases filtration efficiency but also backpressure.
Materiale
Cordierite or Silicon Carbide
Common substrate materials used for thermal shock resistance and filtration performance.
Intervallo di temperatura operativa
200‑600 °C
Normal operating range for soot trapping and regeneration; may reach higher during active regeneration.
Retropressione (pulita)
2‑10 kPa
Typical pressure drop across a clean DPF — increases with soot load.
Contropressione (carico)
Fino a 25 kPa
Parameter used for diagnostic/regeneration triggers; excessive backpressure indicates soot accumulation.
Efficienza di filtrazione
≥ 95%
Proportion of particulate matter removed from exhaust stream under normal operation.
Regeneration Temperature
~510 °C
Typical DAF automatic regeneration temperature to burn off soot and restore filter efficiency.
Standard di emissione
Euro 6 / EPA17
Common regulatory targets for trucks, ensuring particulate matter limits are met.
Peso
20‑30 kg (varies)
Approximate weight depending on size and housing, influencing installation and handling.
Notes for Decision‑Makers
• Cell Density & Backpressure: Higher CPSI values increase filtration surface area but can raise backpressure, affecting engine fuel economy. Balanced selection is key for fleet efficiency.• Scelta del materiale: Cordierite is common for cost‑effective applications, while silicon carbide offers superior thermal shock resistance for heavy load and high temp duty cycles.• Strategie di rigenerazione: DAF trucks typically initiate automatic regeneration based on backpressure and temperature readings — ensuring timely filter cleaning preserves engine performance and reduces downtime.
