4 Cycle Theory
This type of ignition uses an air fuel mixture to ignites a combustion event creating power
Spark Ignition
The name of the park that creates spark
Spark Plug
Transfers power to an applied use.
Power Take Off
Where is the piston located at the intake event?
TDC
The first event in the 4 cycle engine.
Intake event
The "shaft" or the "gear" that moves the valves up and down
Cam Shaft
The compression ring is located where on the piston
What position are the valves in during the exhaust event?
Open
What direction is the piston moving during the "Power" or "Combustion" stroke?
Down
The part that turns linear energy into rotational force
Crankshaft
What is the purpose of the wiper ring on the piston?
To wipe the excess oil off the inside the combustion chamber
Filler piece between the cylinder block and the cylinder head.
Head gasket
Period during engine operation when both intake and exhaust valves are open at the same time is called what?
Valve Overlap
This part aides in the momentum of the engines and also gives the spark plug an initial spark
Flywheel
What part connects the piston to the crank to transfer linear motion to rotational motion?
Connecting Rod
What type of engine has the valves and other related components are located in the cylinder head.
OHV engine
The difference between the volume of the combustion chamber at TDC and BDC is called
Compression Ratio
Surface where the crankshaft rotates.
Bearing Journal
These are used to reduce friction and maintain the proper spacing between various components
Bearings
Distance up and down the piston travels from Top dead center (TDC) to bottom dead center (BDC)
Stroke
