Engine Parts Piston Ring R2 For Mazda R201-23-130A

The gas ring mainly plays the role of sealing and preventing air leakage of the cylinder, followed by the heat transmitted from the top of the piston to the cylinder liner, and then the heat is taken away by the cooling water. The oil ring itself can store some of the oil, which is used to lubricate the Cylinder Liner, and can also scrape the excess oil from the cylinder liner. If the piston ring is damaged, the power of the engine will decrease, and it will cause oil deterioration. The piston may also be in direct contact with the cylinder wall, causing the cylinder to knock, which shows the importance of the piston ring to the car. Generally, as long as the exhaust gas emitted by the car is blue, it can basically be judged that the piston ring is faulty.
