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
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
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
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
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
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.

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
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
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
“Easy to maintain” enginethanks to a very accessible compartment Filling COMPRO
An easy to maintain engine compartment Expansion valve + filter + pressure sensor + electro valve Pressure indicator Engine isolation valve Filling General isolation valve COMPRO
