  1. CITY BUS RANGE – standard vehicles Citelis 12 CNG by Irisbus IVECO GX 327 CNG by Heuliez Bus for TAN COMPRO

  2. CITY BUS RANGE – articulated vehicles New GX 427 CNG by Heuliez Bus Citelis 18 CNG by Irisbus IVECO COMPRO

  3. The energy cost : CNG • Average European CNG public price is 56% of gas oil price (energy content) • Professional price is around 40-50% of gas oil price (energy content) Source COMPRO

  4. The energy cost : CNG versus Oil Source • Natural gas price is still linked to oil price (indexation on the continental Europe on fuel oil and heating oil) • Price difference between oil and natural price is increasing. COMPRO

  5. The CNG experience of Irisbus IVECO • The first IVECO CNG city bus was built in 1991. • Since that year, Irisbus IVECO has gained 17 years of experience in CNG technology in countries such as : France, Italy, Spain, Greece, Australia... • Irisbus IVECO, is the leader in Europe with more than 3 500 CNG city buses built up to now. COMPRO

  6. Innovations of the CNG Citelis of IRISBUS Our Strategy: Think CNG! Most advanced engine technology • Highest environmental performance • Increased autonomy • Specific safety strategy • High speed enhanced road holding COMPRO

  7. Cursor 8 F2G : The most advanced engine technology • Stoechiometric combustion • EEV Emission level • Very important specific power (28 kW/liter), high torque at low rpm • Very good efficiency => 33% in average on an ETC cycle. • Low noise. • Double stage expansion valve => accuracy of control • Self adaptation to gas quality COMPRO

  8. Fuel consumption and pollution emission of Citelis 12 CNG, with Cursor 8 F2G, measured by the University of Graz in Austria • The 9040 cycle is representing a mix “urban/interurban” operation. • The “Brauschweig” cycle is an urban operation (average Speed 23km/h), very representative of city bus operation in Germany. COMPRO

  9. Cursor 8 : The most advanced engine technology COMPRO

  10. Results on the Braunschweig cycleBenchmarking development program made by Graz University in Austria Irisbus Source and TU Graz vehicles 2 axles loaded at 3 tons or corrected in fuel consumption (2,15 liters gas oill per ton) Real life type cycle (Braunscweig bus cycle) COMPRO

  11. An increased autonomy .8 tanks (10 for artic.) RAUFOSS fiber / polypropylene of 154 liters each : 1 232 liters ( or 1 540 liters for artic.) . Higher autonomy A crash resistance of 6.5G COMPRO

  12. A specific safety strategy .Serial fast filling (1kg/s) . Max pressure = 220 bar maxi . Electro valve + thermal fuse on every tank .Tank overpressure detection . Crash sensor => Engine stop . Specific hood for the venting of the tanks COMPRO

  13. “Easy to maintain” enginethanks to a very accessible compartment Filling COMPRO

  14. An easy to maintain engine compartment Expansion valve + filter + pressure sensor + electro valve Pressure indicator Engine isolation valve Filling General isolation valve COMPRO

  15. Enhanced road holding • Anti-roll bars are available as optional. Anti-roll bar COMPRO

  16. Enhanced road holding • Anti-roll bars are available as optional. Anti-roll bar COMPRO

  17. Future evolution of IVECO CNG Offer • An evolution of Cursor 8 which could meet the future Euro 6 norm before the end of 2009. • Therefore CNG will always have one norm ahead. COMPRO

  18. Thank you for your attention… COMPRO
