  1. V8 ENGINE By: Nolan Quinn Cooper Cyr Simeon Marklin

  2. How The Engine Works • Intake Valve brings combination of air and fuel into combustion chamber • Pistons housed in cylinder • 8 cylinders at right angle= V8 • Gas injected to combustion chamber, top of cylinder • The piston compresses gas, spark plug ignites gas and drives piston • Piston rod turns crankshaft • Crankshaft turns wheels • cylinder head controls explosions • Exhaust valve it opens and releases burnt exhaust after ignited. • This all happens simultaneously and continuously • Happens in 4 strokes. • Stop 2:20 http://www.youtube.com/watch?v=erzZ_ri9HOQ http://www.youtube.com/watch?v=Y0KV1Fq-caM&NR=1

  3. ENGINE START-UP ENERGY CHANGES • Key turns using rotational mechanical energy tells the battery to release chemical energy which is changed to electrical energy which fires the solenoid. • The firing of the solenoid is mechanical energy (that was transferred from electrical energy) completes a large circuit which transfers electrical energy to the spark plug.

  4. Energy Changes • Spark creates explosion= electrical energy turns to chemical and heat energy • Explosion expands compressed gas down forcing pistons down= vibration mechanical energy • Piston driving down causes crankshaft to turn= changing vibrational to rotational energy • Heat from the combustion chamber is sent out in the exhaust this is a heat change.

  5. HEAT ENERGY • Explosions expanding gas and propelling pistons downward • Exhaust from exhaust valve

  6. MECHANICAL ENERGY ROTATIONAL: • Turning crankshaft • Wheels turning • Radiator belts VIBRATIONAL: • Pistons pumping RECTALINEAR • Car moving

  7. ELECTRICAL ENERGY • Battery to sparkplug • Battery to electrical components in car

  8. Chemical Energy • Energy coming from battery is chemical • Explosions of air and gas mixture which is chemical.

  9. Lubrication System • Oil pan at bottom of engine • Pump pumps oil to pistons and crankshaft • Crankshaft spins into oil pan take oil • http://www.youtube.com/watch?v=1dYdJvavaJo&feature=related

  10. Overview • Key turns, initiating battery to send chemical energy, changed to electric energy • Fires the solenoid completing circuit • Starts spark plug, ignites compressed gas=chemical and heat change • Piston drives down= vibrational mechanical energy • Piston Rods turn crankshaft=rotational mechanical energy • Crankshaft turns wheels=rotatational • Car moves=rectilinear
