Erweiterte Forschungsbegleitung für den Einsatz von energieeffizienten Linienbussen im Verkehrsverbund Rhein-Ruhr

Within the EFBEL project, city buses with hybrid and alternative power trains are subject to examination. Based on the experience gathered in a preceding project, the following topics will be covered in depth:

• Dedicated measurement of fuel consumption, exhaust and noise emissions
• Energy balance of main auxiliary systems
• Identification of main impact factors on fuel consumption using simulation and analysis of load profiles
• Analysis of the impact of operating concepts and driver behavior
• Analysis of route profiles and topography features with respect to their impact on operating modes
• Examination of the development of fuel consumption considering service life
• Description of weather related phenomena and their influence on fuel consumption and availability (winter vs. summer)

The following vehicles are to be examined:
