Piston Ring for Truck Engine 8DC8A Machinery engine repair parts ME090574

SPECIFIIONS:

TYPES OF PISTON RING:

CAST IRON RINGS :

These rings are made from graded Prelatic Cast Iron alloy. Machined to close tolerances as recommended by O.E. (Original Equipment)

STEEL RING CHROME PLATED :

These rings are made of high Tensile special steel machined to proper sizes with Chrome plating from 100 to 200 microns as required by the buyers. This is used in Heavy Duty Diesel Engines.

SG IRON CASTED RINGS :

These rings are made of SG Iron castings and recommended for Heavy Duty Diesel Engines, specially 3 ring design Piston.

PISTON RING FUCTION:

Piston ring functions include sealing, adjusting oil (oil control), heat conduction (heat transfer),

and guiding (supporting). Sealing: It means sealing the gas, preventing the gas in the combustion chamber from leaking to the crankbox, keeping the leakage of the gas to a minimum and improving the thermal efficiency. Air leakage not only reduces the power of the engine, but also degrades the oil. This is the main task of the air ring.

Adjusting the oil (oil control): scraping off the excess oil on the cylinder wall while making the cylinder wall thin The thin oil film ensures normal lubriion of the cylinder and piston and ring, which is the main task of the oil ring. In modern high-speed engines, special attention is paid to the role of the piston ring to control the oil film; heat conduction: the heat of the piston is transmitted to the cylinder liner through the piston ring, that is, cooling. According to reliable data, 70-80% of the heat received by the piston crown in the non-cooling piston is dissipated through the piston ring to the cylinder wall. 30-40% of the cooling piston is transmitted to the cylinder through the piston ring. Supported by: the piston ring keeps the piston in the cylinder, preventing the piston from directly contacting the cylinder wall, ensuring smooth movement of the piston, reducing frictional resistance, and preventing the piston from knocking on the cylinder. The piston of a general gasoline engine uses two gas rings and one oil ring, while the diesel engine usually uses two gas rings and one oil ring.
