OE ZMY0-11-SCO Piston Ring 1.6L for Mazda ZM-YE 78.0mm with 0.011mm Precision

The piston ring creates a sealing layer between the piston and cylinder wall, preventing gas and oil leakage from the compression chamber and combustion chamber. This ensures efficient internal combustion engine operation while minimizing environmental pollution.

• First Ring (Upper Oil Ring): Positioned at the top, it collects fuel from direct injection systems and directs excess fuel back to the combustion chamber
• Second Ring (Power Ring): Located below the first ring, it seals the cylinder to prevent gas leaks and guides exhaust gases to the exhaust system
• Third Ring (Centralizer Ring): Positioned below the second ring, it stabilizes piston movement along the cylinder wall to reduce wear and friction

Piston rings are critical components in internal combustion engines, manufactured from durable metal materials including cast iron, cast steel, and specialized steel alloys to withstand high-temperature, high-pressure operating conditions.

With years of specialized experience, we focus on the research, development, production, and sales of high-performance piston rings. Our advanced manufacturing equipment and technical expertise ensure consistent product quality and continuous innovation in automotive engine components.
