Workshop

08:00 AM - 08:30 AM Registration & Welcome Coffee

Challenges in vehicle emissions measurements
  • Partial sampling systems: Variable dilution ratio, Constant dilution ratio
  • Raw exhaust measurements
  • Full scale dilution systems: Dilute bag, Dilute continuous
  • General issues: Instrument ranges [Species (example CO), Fuels (example diesel vs. CNG)], Condensation in tunnel, Particulate measurements (weight based)
