The piston ring H 34026 plays a crucial role in sealing the combustion chamber of the ASL25 engine, maintaining compression while controlling oil consumption. Positioned on the piston, it prevents gas leakage and ensures efficient power transfer during each combustion cycle. Built from wear-resistant alloys, the ring endures high thermal and mechanical stresses, contributing to both engine efficiency and reduced emissions. Regular inspection and timely replacement of piston rings are essential to sustaining the long-term reliability and performance of the engine.
