КОЛЬЦО ПОРШНЕВОЕ В СБОРЕ Caterpillar 5027233

An Engine Standard Piston Ring fits around the piston and forms a seal between the piston and cylinder wall during engine operation. It helps contain combustion gases within the combustion chamber, allowing proper compression for efficient power generation. It controls the amount of engine oil on the cylinder wall by spreading a thin film and returning excess oil to the crankcase. It reduces blow-by by preventing gases from escaping into the lower engine area.Attributes:• Assists in transferring heat away from the piston.• Helps prevent loss of engine power due to compression leakage.• Controls engine oil distribution along the cylinder wall.• Indicates the piston ring is sized for a cylinder bore enlarged by 0.25 mm for proper fit.Applications: An Engine Standard Piston Ring is located in grooves around the piston inside the engine cylinder, where it seals combustion gases, controls oil flow along the cylinder wall, and maintains compression.
