| Piston Introduction: a sliding plug that fits
closely inside the bore of a cylinder. Its purpose is either to
change the volume enclosed by the cylinder, or to exert a force on
a fluid inside the cylinder. The pistons are cup-shaped
cylindrical castings of steel or aluminum alloy. The upper, closed
end, called the crown, forms the lower surface of the combustion
chamber and receives the force applied by the combustion gases.
Most pistons in an internal combustion engine have piston rings. Usually there are two compression rings as a seal between the piston and the cylinder wall, and one or more oil control rings below the compression rings. The head of the piston can be flat or bulged or otherwise shaped. Pistons can be forged or cast. A special type of cast pistons is the Hypereutectic piston.
