PRESS FOR NEXT SLIDE PRESS TO END SLIDESHOW  Burning gasoline to power vehicles pollutes the air and causes smog  Emissions from cars contribute to global warming  You can help save the environment by using fuel more efficiently Vehicle Pollution and the Environment 2

With this setup you can:  Check out new vehicle technologies and how they can improve fuel economy  Test different driving habits and see how YOU can save fuel to help the environment PRESS FOR NEXT SLIDE PRESS TO END SLIDESHOW chevrolet-corvette-photo-105.jpg silverado-hybrid-11.jpg 3

PRESS FOR NEXT SLIDE PRESS TO END SLIDESHOW Internal Combustion Engine (Gas) Vehicles  A mixture of gasoline and air powers the engine  Engine emissions pollute the air  Only about 14-26% of fuel energy is used – much of it is lost in the engine as heat 4

PRESS FOR NEXT SLIDE PRESS TO END SLIDESHOW Hybrid Vehicles  They are powered by both an electric motor and a gasoline engine  Regenerative braking turns vehicle kinetic energy into reusable electricity while braking  Engine turns off when the car is stopped; restarts when the car moves 5

PRESS FOR NEXT SLIDE PRESS TO END SLIDESHOW Electric Vehicles (EV)  Rechargeable batteries provide power to an electric motor  Less use of fossil fuels  EVs convert over 80% of battery energy to power the wheels  No exhaust gas! 6

Energy Losses and Vehicle Efficiency: There are a lot of reasons why a vehicle loses energy. Some of the main reasons are:  Air resistance  Rolling resistance Type of vehicle you drive Your driving style Amount of fuel used  Engine losses PRESS FOR NEXT SLIDE PRESS TO END SLIDESHOW  Driving style 7

More speed More energy lost  Air resistance is directly proportional to the square of the vehicle’s velocity PRESS FOR NEXT SLIDE PRESS TO END SLIDESHOW 8

 Low tire pressure increases rolling resistance PRESS FOR NEXT SLIDE PRESS TO END SLIDESHOW  Rolling resistance is related to the mass of the vehicle and the rolling coefficient 9

 By using less engine RPM, you can lower engine losses  Engines need to breath! Keep engines’ air filters clean to save fuel PRESS FOR NEXT SLIDE PRESS TO END SLIDESHOW Engine Losses ette_Z06/400/06_Corvette_Z06_inengine.jpg Engine speeds are measured by Rotation Per Minute or Engine speeds are measured by Rotation Per Minute or RPM 10

 Drive slower to help lower air resistance  Make sure your tire pressure is right. Low tire pressure increases fuel consumption  Don’t drive aggressively! Try not to brake or accelerate more than you need to PRESS FOR NEXT SLIDE PRESS TO END SLIDESHOW Tips For Better Driving 11
