  1. What is What will be UNDER THE HOOD and IN THE TANK ? By John Zavalney

  2. A one day introduction to ALTERNATIVE CLEAN FUEL for transportation I. Internal Combustion Engines II. Fuels; pros & cons A. How it works A.Fossil Fuels B. Efficiency 1. Gasoline C. Pros & Cons 2. Diesel D. Why Change B Alternatives 1. Electric 2. Hybrid 3. Hydrogen 4. Linkvolt

  3. Internal Combustion Engine (ICE)How it works http://www.rkm.com.au/ANIMATIONS/animation-4-stroke-engine.html

  4. Internal Combustion Engine (ICE)How it works • Combustion of a FUEL in a chamber • With an oxidizer usually air • Produces increases in temperature and pressure in the chamber • That pressure applies a force to a piston or turbine blade • Detailed explanation and animation • of how an ICE works • http://auto.howstuffworks.com/engine1.htm

  5. Internal Combustion Engine (ICE)Efficiency About 12.6% of the energy that goes into the tank is used to move the vehicle • ICE engines lose 62.4% to • Friction • Heat • Pumping air

  6. Internal Combustion Engine (ICE)Efficiency How much of the energy from gasoline goes to moving you? http://www.fueleconomy.gov/FEG/atv.shtml Planet Green How Stuff Works video clip http://auto.howstuffworks.com/hybrid-greenwash.htm

  7. Internal Combustion Engine (ICE)Pros & Cons PROS • Relatively efficient (compared to an external combustion engine) • Relatively inexpensive (compared to a gas turbine) • Relatively easy to refuel (compared to an electric car) • CONS • Rapidly decreasing availability of gasoline worldwide • Harmful exhaust emissions into atmosphere (CO, CO2, hydrocarbons, etc.)

  8. Internal Combustion Engine (ICE)Why Change? • In 1970, there were 200 million cars in the world1 • In 1990, there were almost 500 million1 • In 1997 there were over 600 million2 • If present trends continue, the number of cars on Earth will double in the next 30 years2

  9. Internal Combustion Engine (ICE)Why Change? Cars in the USA are 33% larger than the average car in the world

  10. Internal Combustion Engine (ICE)Why Change? • 600gl: Average amount of gasoline consumed by one U.S. car each year. • 12,000lbs: Amount of carbon dioxide emitted from one U.S. car each year.

  11. Internal Combustion Engine (ICE)Why Change? • The U.S. has less than 5% of the worlds total population. • U.S. car contribute almost 50% of the worlds automotive green house gases

  12. Internal Combustion Engine (ICE)Fuel OptionsFossil Fuels: Gasoline & Diesel • PROS • Less expensive than other fuels • Less expensive to run • CONS • Made from a petroleum not common in the U.S. • Does not burn cleanly • It is a pollutant • Limited supply
