Piston
Rings
Piston ring is the metal ring used in piston
grooves, divided into 2 types, compression ring and oil-control
ring. Compression ring is used to seal the mixture gas in
combustion chamber, while oil-control ring is to strike off the
engine oil on cylinder. Piston ring is a metal flexible ring with
high expand deformation, which seals the cylinder depending on the
pressure difference between the gas and
liquid.
The main functions of the piston ring are
sealing, oil-controlling, heat transmit,
guiding.
Sealing
means to seal the gas, to prevent the gas in combustion chamber
into crankshaft, to control the leak of the gas and to raise the
efficiency of the heat. The leak of gas is not only to decrease the
engine power, but only to deteriorate the engine
oil.
Its
the main function of the compression ring.
Oil-controlling means to strike off the
redundant lubricant oil from the cylinder wall with oil mask on
cylinder wall to ensure the lubrication between cylinder, piston
and ring.
Its
the main function of the oil-control ring, which is a key factor in
modern high speed engine.
Heat transmit means to transmit the heat to
cylinder liner to cool down.
Guiding means to make piston move smoothly in
cylinder, to prevent direct contact between piston and cylinder
wall, to lower the friction power and prevent piston to hit the
cylinder.
Material of the piston rings were cast iron
in early time, as the technology improvement, steel piston rings
were invented, and as the improvement of engines, many surface
treatment was applied, including, spraying,electroplating,chrome
plating, nitridation, physical deposition, surface coating, and
Zinc manganese series phosphating
