DAF DPF

DAF Diesel Particulate Filter (DPF) Technical Parameters

매개변수
Typical Value
설명

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.

세포 밀도(CPSI)
200 / 300 / 400 / 600
Cells per square inch indicating filtration surface area — higher CPSI increases filtration efficiency but also backpressure.

재료
Cordierite or Silicon Carbide
Common substrate materials used for thermal shock resistance and filtration performance.

작동 온도 범위
200‑600 °C
Normal operating range for soot trapping and regeneration; may reach higher during active regeneration.

역압(클린)
2‑10 kPa
Typical pressure drop across a clean DPF — increases with soot load.

배압(로드됨)
최대 25kPa
Parameter used for diagnostic/regeneration triggers; excessive backpressure indicates soot accumulation.

필터링 효율성
≥ 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.

배출 기준
Euro 6 / EPA17
Common regulatory targets for trucks, ensuring particulate matter limits are met.

무게
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.• 재료 선택: Cordierite is common for cost‑effective applications, while silicon carbide offers superior thermal shock resistance for heavy load and high temp duty cycles.• 재생 전략: DAF trucks typically initiate automatic regeneration based on backpressure and temperature readings — ensuring timely filter cleaning preserves engine performance and reduces downtime.
