Improvement of wear resistance and efficiency of piston internal combustion engine

Abstract

The article examines the specific features of piston ring operation in internal combustion engines and proposes a new design to improve their wear resistance and efficiency. The piston ring, critical for sealing the combustion chamber, can create friction that affects the engine's durability and efficiency. Under conditions of high load and frequent wear, the importance of improved design solutions becomes evident.

The proposed piston ring design includes the innovative use of graphite as a solid lubricant to reduce friction and enhance sealing. As a result of these design changes, based on a graphite coating and stepped joints, significant friction loss reduction and improved sealing were achieved. Tests on a prototype confirmed the effectiveness of the proposed design, showing reduced friction and energy loss, which positively impacted engine lifespan and overall performance.

The results demonstrate the potential of the proposed solution for both traditional engines using motor oil and oil-free engines. Future plans include creating a test stand for more detailed testing and optimization of the piston ring segments, which will help ensure maximum engine performance and durability.
