Intake Valve- opens at the proper time to let in air and fuel. Valve Cover- Protects the valves and the valve springs.
Keeps dirt out and lubricating oil in. Intake Port- the passageway in a cylinder head for the fuel
and air to pass through. Head- a platform containing most of the parts of the
combustion chamber. Coolant- circulating water and antifreeze to keep the
temperature regulated. Exhaust Valve- open at the proper time to release the
exhaust
Back
Spark Plug- A device, inserted into the combustion chamber for firing an electrical spark to ignite air-fuel mixture

Compression- The process of compressing the air-fuel mixture in the cylinder to make it more combustible
Back
Combustion-The process of igniting the compressed air-fuel mixture to create motion and the over all power of the engine.
Back
Exhaust- The process of releasing the exhaust out of the cylinder through the exhaust valve.
