  1. Better Air Quality 200613-15 December, 2006Yogyakarta, IndonesiaOn-Board Measurement of Heavy Duty Vehicles In-UseLennart ErlandssonAVL MTC AB, Sweden

  2. Company Presentation • Located in Stockholm, Sweden • Emission measurement since 1970 • Privately owned since 2002, before under governmental operation • New laboratory 1990 • 11 test cells in operation • 4.5 km test track • Field of activities • Certification • Engine Development • Research & Development • Consultancy Services • Approximately 60 employees • Accredited third party laboratory • Member of a world-wide network

  3. Presentation Background/History Applications Correlation Portable Emission Measurement System (PEMS) vs. Chassis Dynamometer test Test results Summary On-Board Measurement (OBM)

  4. Background/History • Measurement of “real-life” emissions • Certification procedure for engine • Very few HDV emission laboratories available, due to high costs • PEMS less expensive test method but with sufficient quality • In-use compliance testing of HDV according to EU Directive 2005/55/EC • PEMS-protocol (Europe) • NTE-procedure (USA)

  5. In-Use Compliance testing of HDV Establishment of “local” emission factors Emission levels for vehicle fleet, EDB Verification of emissions for off-road applications, ships, locomotives Measurement of stationary sources Intelligent design of bus route net Application engineering/ECU optimization Applications

  6. Correlation (Steady-State) Source: EC, JRC

  7. Correlation (Transient)

  8. Testing on-road • Test of 3 heavy duty vehicles • Truck, 9 liter engine, Euro III • Bus, 11 liter engine, Euro I • Truck, 10 liter engine, Pre-Euro/high emitting • Trip duration app. 40 minutes, average speed app. 20 km/h, length app. 14 km • Tested during “normal operation” (bus route)

  9. Testing on-road

  10. Testing on-road Euro III High emitting Euro I

  11. Testing on-road (PEMS) • Test of three identical trucks • Three tests of every vehicle • Tested during “normal” operation • Trip duration app. 80 minutes, average speed app. 56 km/h, length app. 75 km • Cylinder displacement 9 liter • Engine power 190 kW @ 1900 rpm • Emission performance Euro III • Gross vehicle weight 20 ton

  12. Testing on-road (PEMS)

  13. Testing on-road (PEMS)

  14. Testing on-road (PEMS) Repeatability of test results from 3 test runs of the same vehicle

  15. Observations • For extended testing time, a separate gen set is recommended as power supply • The heated sample line from the EFM to the analyzer is recommended to be at least 5 m • Installation on the vehicle need good preparation, special concern to exhaust pipe • Measurements according to PEMS-protocol require full access to vehicle ECU • Exceedance of max width (2.60 m) of vehicle can be a problem

  16. Conclusions • PEMS is a robust and reliable system for measurement, meeting acceptable criteria for quality and accuracy • PEMS can be used for different applications • PEMS can to some extent replace a chassis dyno test cell for heavy duty vehicles • Measurements according to PEMS-protocol require assistance by vehicle manufacturer (new EU directive require full access)
