Detroit 71 Series Diesel Engine Piston 5149234 5102780

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Combustion Force Transfer: Transfers energy from diesel combustion to the crankshaft, enabling power generation in heavy-duty engines.
  • Enhanced Sealing & Lubrication: Grooves and raised ring designs ensure a tight seal between the piston and cylinder wall, while oil/coolant channels reduce friction and heat buildup.

Key features

  • 1. Material Technology

    • With a corrosion-resistant steel/aluminum alloy body, this piston withstands extreme temperatures and pressures in diesel engines longer than standard cast-metal pistons*. The polished surface and heat-treated finish enhance durability in harsh operating conditions.

  • 2. Modular Design Adaptability

    • With a modular design featuring adjustable grooves and ring configurations, this piston easily adapts to diverse diesel engine specifications compared to rigid, non-modular designs*. This flexibility ensures compatibility with various engine types and sizes.

  • 3. Performance Parameters

    • Precision-engineered sealing rings and lubrication grooves reduce gas leakage by up to 20%*, improving combustion efficiency and power output. The oil passage channels optimize heat dissipation, enabling sustained performance in high-load scenarios.

  • 4. Scenario Solutions

    • Designed for continuous commercial use, this piston handles heavy-duty diesel engine operations more reliably than standard pistons in intermittent-use applications*. Its robust construction ensures stability in environments requiring prolonged running, such as trucks or generators.

  • 5. Certification Standards

    • RoHS-certified materials ensure compliance with global environmental regulations, unlike non-certified alternatives*. This guarantees reduced exposure to hazardous substances, aligning with eco-conscious manufacturing practices.

Supplier's note

  1. Key Technical Breakthroughs:

    • Precision Grooves: Enhanced sealing efficiency reduces fuel waste by up to 12%.
    • Thermal Coatings: The Pro Model’s DLC coating extends lifespan by 30% in high-heat environments.
    • Modular Design: Adjustable bore sizes accommodate 90% of diesel engine variants, reducing inventory costs.

  2. Version Selection Guide:

    • Base Model: Ideal for standard diesel engines (e.g., light commercial vehicles) requiring cost-effective performance.
    • Advanced Model: Suitable for medium-duty applications (e.g., agricultural machinery) needing lighter weight without compromising durability.
    • Pro Model: Engineered for heavy-duty engines (e.g., mining equipment) where extreme thermal resistance and longevity are critical. With its DLC coating, the Pro Model outperforms industry benchmarks by maintaining integrity at 520°C—20% higher than traditional pistons. Pair this with its lightweight design to reduce mechanical strain and improve fuel efficiency.

*Comparative improvement over industry standard benchmarks.
