V8 ENGINEBy: Nolan Quinn

Cooper CyrSimeon Marklin

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.

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.

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.

HEAT ENERGY

Explosions expanding gas and propelling pistons downward

Exhaust from exhaust valve

MECHANICAL ENERGY

ROTATIONAL: Turning crankshaft Wheels turning Radiator beltsVIBRATIONAL: Pistons pumpingRECTALINEAR Car moving

ELECTRICAL ENERGY

Battery to sparkplug Battery to electrical

components in car

Chemical Energy

Energy coming from battery is chemical

Explosions of air and gas mixture which is chemical.

Lubrication System

Oil pan at bottom of engine

Pump pumps oil to pistons and crankshaft

Crankshaft spins into oil pan take oil

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
