ABOUT PISTON RING
A piston ring must possess both spring-like tension and the properties to become a true circle when closed simultaneously. Piston rings keep a close contact with the cylinder walls through their own spring tension, carrying out three main functions below in reciprocating engines as:
FUNCTIONS
Top Compression ring
Located in the first ring groove which has the primary function of sealing the combustion gases and transferring heat from the piston to the cylinder wall.
Second Compression ring
Located in the second ring groove which has dual-purpose of assisting the top ring and also the control of oil so that the top ring has enough lubrication.
Oil control ring
Prevent the oil from passing between the face of the ring and the cylinder through the gap.
MATERIALS
Cast iron, FCD, Steel
COATINGS AND TREATMENTS
Chromium plated, Nitrided, Phosphated, Copper plated
SER PISTON RINGS
To enhance the wear resistance and durability, SER PISTON RINGS undergo nitriding and chroming on top ring and oil ring. Moreover, a thinner ring width which reduces the weight of piston contributes to improving fuel efficiency.
SER TOP & SECOND COMPRESSION RINGS
Undergo chromium plated, copper plated and phosphated surface treatment.
SER OIL CONTROL RINGS
555 TYPE for diesel engines.
777 TYPE for gasoline engines.
APPLICATIONS
To all engines, automobiles, trucks, forklift, compressors, generators, outboard motors, construction machines, agricultural machines, etc.
A piston ring must possess both spring-like tension and the properties to become a true circle when closed simultaneously. Piston rings keep a close contact with the cylinder walls through their own spring tension, carrying out three main functions below in reciprocating engines as:
- Sealing the combustion chamber so that there is no transfer of gases from the combustion chamber to the crank.
- Supporting heat transfer from the piston to the cylinder wall by thermal conduction.
- Regulating engine oil consumption as controlling the thickness of the lubricating oil film on the cylinder wall.
