Diesel Engines Engine
Regeneration Intervals
• Depending on the operating conditions of the vehicle the DPF is regenerated every
100…300 km. Due to the ash residues that have formed from the engine oil and diesel
fuel the usable filter volume is reduced. Since the ash amount accumulated in the DPF
increases with every regeneration process, the regeneration intervals become shorter
with rising mileage.
NOTE: High fuel consumption, low fuel quality (high sulphur content) and high engine oil
consumption accelerate the accumulation of ash in the DPF, shortening the
regeneration intervals more quickly.
