The PISTON RING 2AZ is a high-performance metallic component engineered to fit precisely into the grooves of an engine piston, serving as a critical part in maintaining optimal engine functionality. As a key engine component, it is categorized into two main types: compression rings and oil rings, each with distinct roles in ensuring efficient engine operation.

The compression ring is designed to create a tight seal within the combustion chamber, preventing the leakage of combustible gas during the combustion process—this seal is vital for maximizing engine power output and fuel efficiency. Meanwhile, the oil ring functions to regulate oil distribution by scraping excess lubricant from the cylinder walls, ensuring proper lubrication without oil entering the combustion chamber, which could otherwise lead to increased emissions or reduced performance. Together, these rings fulfill four core functions: sealing, oil control, heat conduction (transferring heat from the piston to the cylinder wall), and guiding the piston’s movement within the cylinder.
