§ Slides, exercises,solutions,announcements,…
Mode of Exercises• no standard calculation tasks• rather vaguely described tasks• many unknowns• assumptions necessary• several solutions possible• similar to “real” engineering work• work in teams → distribute work
Ø One exercise lasts ~2-3 weeksØ Every week we check your progress via a milestoneØ After 2-3 weeks:
each group presents own solution in a 5 min presentation
Deliverables
• Visit www.polybox.ethz.ch• Create new folder• Name it «VPS_TeamXX»,
where XX is your teamnumber (01, 02, 03,…)
• Share with your team-mates and with «anritter» and «andyno»
Polybox
• System integration apps available for Mac OS, iOS, Windows, etc.
• 50 GB of storage available• Your Data stays within ETH Zürich• Upload links for externals without registration
Deliverables
• Upload your notes and calculations for everymilestone until Friday 8am.
• We will read and check until exercise lectureat 12:15pm.
• After a presentation, upload your slides
• If you decide to work within your folder, create subfolders «ExerciseX/Deliverables», where X is the exercise number.

Standard vs. VPS Exercise
• Full information• Difficult math• Textbook formula• Assumptions given• Stick to question• No presentation
no verbalization• No discussion
• Little to no information• Simple math• Understand physics• Make own assumptions• Think beyond question• Presentation &
verbalization• Critical discussion
Verbalization is important for oral exams!

Goal of Exercise
• Develop understanding about the possible energy conversion chains involved in individual mobility
• Investigate the CO2 footprint of various powertrain technologies
• Establish fair basis to trade-off benefits against drawbacks
Exercise #1
Calculate and compare the best/worst-case CO2emissions of a compact vehicle driving the New European Driving Cycle with the following types of propulsion systems:• Internal combustion engine,• Battery and electric motor.
Exercise #1
• Define possible in-vehicle and upstream conversion processes
• Calculate energy-specific CO2 for the cases where fossil fuel is involved
Hints• Use the book: Vehicle Propulsion Systems,
Third Edition• Check Fig. 1.3 to 1.6 and Table 1.1 • NEDC assumptions in section 2.2.2• Use following units:
– kW for Power– kWh for Energy– l/100km for Fuel Consumption– kWh/km and MJ/100km for Electric Energy
Consumption– kg/100km and g/km for CO2 Emissions
