Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Sealing Efficiency: Designed to seal the gap between pistons and cylinder walls in diesel engines, preventing gas leakage and ensuring optimal combustion efficiency.
  • Wear Reduction: The toothed inner ring (typically bronze/aluminum) minimizes friction and wear, extending engine longevity.

Key features

  • 1. Material Technology

    • With corrosion-resistant cast iron and durable steel construction, you can ensure long-lasting performance in harsh diesel engine environments. The toothed inner ring made of bronze or aluminum reduces friction and wear compared to standard iron-only designs*

  • 2. Interactive Design

    • With precision-toothed inner rings engineered for optimal cylinder wall interaction, you can maintain a tight seal under high-pressure conditions, outperforming smooth designs in wear resistance*

  • 3. Performance Parameters

    • With advanced sealing technology, you can achieve up to 20% improved combustion efficiency in diesel engines compared to standard piston rings, minimizing gas leakage and optimizing power output*

  • 4. Scenario Solutions

    • Designed for heavy-duty diesel engines, you can ensure reliable operation in commercial or industrial settings requiring continuous use, such as trucks or generators*

  • 5. Certification Standards

    • Manufactured to OEM certification standards, you can guarantee compatibility and performance in original diesel engine setups, ensuring seamless integration with specified models like 4089501 and 3068813*
