  1. Kon-0.1100 - General information in Machine technology: Group 8Environmental Aspects of Various Traffic Powertrain OptionsSpecial focus on Hybrids & EVs
  2. Types of Powertrain NB: All stated efficiencies are “Tank to Wheel”, NOT “Well to wheel”. For EVs, implies “plug to wheel”, not “power plant to wheel”
  3. Types of Powertrain (2) NB: All stated efficiencies are “Tank to Wheel”, NOT “Well to wheel”. For EVs, implies “plug to wheel”, not “power plant to wheel”
  4. Power train emission characteristics for passenger cars
  5. EU’s targets EU’s target is to reduce emissions from 1990 levels by 20 % by 2020 EU’s target (CO2 emissions) for a new passenger car is 130 g/km at 2015 95 g/km at 2020 a new van is 175 g/km at 2017 147 g/km at 2020 EU is aiming to increase the share of the renewable energy to 20% of the final energy consumption by 2020
  6. Arska is hydrogenguytoo Oil is easyanswer
  7. Electric car Efficiency in electric cars is 85% (30-32%) when in petrol cars its 20-25% Energies that some batteries can hold: Lead battery 20-40 Wh/kg Lithium-ion battery 70-130 Wh/kg Petrol can hold about 12 000 Wh/kg Companies are developing new and better batteries so electric cars can run longer Today most used batteries are lithium and lead batteries To load batteries it takes many hours but new technology is developing that can charge electric cars lot faster Electric cars with lead batteries can travel up to 100 km With new lithium-ion batteries cars can travel 160 km
  8. Hybrids Hybrid electric vehicles (HEVs) use petroleum engine and at least one electric motor Petroleum engine produces energy for propulsion, other technical solutions recycle the energy Batteries store extra energy and electric motor transforms it to thrust Generative breaking and constant engine drive recharge batteries Other green solutions as automatic engine stop and start when not moving are also common in HEVs On low velocities all HEV’s thrust is provided by the electric motor Parallel use of engine and motor reduces fuel consumption and emissions
  9. KERS =Kinetic Energy Recycling System Used in Formula 1 and othermotorsports Energy canbestoredeither as mechanicalenergy as in a flywheel electricalenergy as in a battery Extra 60 kW available for 6.67 seconds per lap Benefit per lap is approximately 0.1 to 0.4 seconds Has a badreputationbecause of highpricetag for smallgain,inreliability and electricshocks
