Energy Conversion
Engines take heat energy and convert it into mechanical energy.
Motors take electrical energy and convert it into mechanical energy.
Basic Parts of the Gasoline Engine
Cylinder block
Piston
Piston rings
Piston pin
Connecting rod
Crankshaft
Piston Rings
The rings seal the compression gases above the piston keep the oil below the piston rings.
Crankshaft
Along the the piston pin and connecting rod it converts the up and down motion (reciprocating) of the engine to spinning (rotary) motion.
