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
