Particle Counting in Diesel Fuel

Why measure particles in diesel fuel?

  • Fuel quality has a direct impact on performance and component longevity
  • Cleanliness, or more specifically particle content, is a key factor in fuel quality
  • Problems caused by particles are blockage, wear and erosion in fuel systems

Diesel Fuel

Fuel cleanliness

  • Cleanliness limits in the World Wide Fuel Charter are presented in terms of particle counting
  • Particle counting is a recognised, established cleanliness determination, with very good repeatability and reproducibility, it is non subjective and available real time

Test methods

  • There are a number of internationally accepted test methods, some of which are mandatory for release of fuel from a refinery
  • Energy Institute test method IP 565 for aviation turbine fuel (mandated in fuel specification Def Stan 91-091)
  • ASTM test method D7619 and D7467 for middle distillate fuels (referenced in D975 diesel spec)
  • The above test methods were developed by Stanhope-Seta using the AvCount light obscuration particle counter
  • ISO EN 590 developing particle counting method
  • Energy Institute will shortly issue IP PM FA, determination of dispersed particles
How does the AvCount Lite SA1800-2 help?

    AvCount Lite Particle Counter

  • A compact, portable instrument that can be battery or mains powered allows use within the distribution network or in the laboratory
  • Samples can be drawn from bottles or on-line with real-time test progress and results displayed, allowing for immediate corrective action
  • Simple to use with an automatic test procedure using only 80 ml fuel (IP 565/ASTM D7619)
  • Pre-programmed with three test methods including ASTM D7619, covering middle distillate fuels including diesels, bio-diesels and bio-diesel blends
