1. What Makes the wheels go? Chapter 1 Pages 1-19

2. How it all fits together Three major sections Chassis Engine Drivetrain

3. How it all fits together--Chassis The Chassis is: Frame Body Passenger compartment The base for all other parts to be connect to

4. How it all fits together--Engine The Engine is: The internal combustion device that supplies power to the vehicle

5. How it all fits together--Drivetrain The Drivetrain is: The transmission and other parts that transfers the power from the engine to the wheels.

6. ****NOTE**** The Engine and the Drivetrain together is called the: POWERTRAIN

7. Energy, Force, Work, and Power The movement of the car results from the use of ENERGY 6 Forms of Energy: -Chemical-Light -Mechanical-Electrical -Heat-Radiation

8. Energy, Force, Work, and Power FORCE (F) causes motion when applied to a car WORK (W) is the result of applying a Force over a Distance (D) W=D*F

9. Energy, Force, Work, and Power POWER is the rate at which WORK is done. Power (P) Work (W) Time (T) P=W/T

10. Energy, Force, Work, and Power HORSEPOWER! This term is much more immediately meaningful when talking about Work and Power. 1 Horsepower (Hp) is 33,000 foot-pounds (ftlb) per minute. Hp=P/33,000

11. Energy, Force, Work, and Power TORQUE The twisting force that drives the wheels

12. Converting Heat Energy Into Motion COMBUSTION (BOOM, that just happened!) The burning of chemical rich gasoline or other fuel produces HEAT ENERGY External Combustion Engine Internal Combustion Engine

13. Converting Heat Energy Into Motion External Combustion Engine

14. Converting Heat Energy Into Motion Internal Combustion Engine

15. The Engine As A Group Of Systems. Electrical Fuel Cooling Lubrication

16. Transferring Torque Transferring torque is taking the power from your engine and moving it through the drivetrain to the wheels Front Wheel Drive (FWD) Rear Wheel Drive (RWD) 4 Wheel Drive (4WD or 4x4) All Wheel Drive (AWD)

17. Brakes You need to make it stop somehow! Two types Disc Drum

18. Steering Controls the direction of the vehicle.

19. Suspension Suspension is essential for Stability and Ride.

20. Tires The single most important components of the vehicle! Much of the safety and comfort depend on tires.
