Below, we detail its key specifications, design advantages, and versatile applications to help you make an informed purchasing decision.

Key Specifications of Piston LF155: Precision Engineered for Balance

Model Specificity: LF155

Critical Dimensions for Optimal Function

• CYL DIA (Cylinder Diameter): 55mm – Optimizes displacement for balanced power and efficiency, while maintaining a tight, leak-proof seal with the cylinder wall to maximize combustion performance.

• TOTAL HIGH (Total Height): 41.5mm – Enhances structural stability, balancing mechanical stress and power delivery for smooth operation under both light and heavy loads.

• COMP DIST (Compression Distance): 23mm – Fine-tunes the engine’s compression ratio, enhancing torque production and fuel combustion efficiency for responsive acceleration across all RPM ranges.

• Piston Ring Specifications: 1.01.02.5mm – A triple-ring configuration (two compression rings + one oil control ring) with extended oil control ring height delivers superior sealing, reduces oil consumption, and prevents carbon buildup.

• PIN DIA (Piston Pin Diameter): 15mm – Reinforced pin diameter provides exceptional load-bearing capacity, ensuring stable power transmission to the connecting rod even in high-stress scenarios.

• PIN LENGTH (Piston Pin Length): 41mm – Offers an optimal contact area with the connecting rod, distributing load evenly to minimize wear and extend the piston’s service life.

  
  

  Precise Manufacturing Process: Craftsmanship You Can Trust

  Advanced Production Technology

  The LF155 piston is manufactured using state-of-the-art 5-axis CNC machining, achieving dimensional accuracy within ±0.003mm—surpassing industry standards. This precision ensures that every piston meets the exact specifications of LF155 engines, eliminating fitment issues and guaranteeing consistent performance across all units. The production process also includes a specialized T6 heat treatment and stress-relief annealing, which strengthens the aluminum alloy and eliminates internal stresses, further enhancing durability and resistance to mechanical fatigue.

  Strict Quality Control Measures

  Every LF155 piston undergoes rigorous quality control inspections at every stage of production:

  Raw Material Testing: Ensures the 2024 aluminum alloy meets aerospace-grade standards for strength and heat resistance.

  Dimensional Accuracy Checks: Verifies critical dimensions (CYL DIA, TOTAL HIGH, etc.) using high-precision laser measuring tools.

  Pressure & Wear Testing: Simulates real-world operating conditions (up to 14 bar pressure) to assess sealing performance and durability.

  Final Inspection: Conducts a comprehensive visual and functional check before packaging, ensuring only flawless products reach customers.

  
  

  Outstanding Performance Advantages: Elevate Your Engine’s Capabilities

  Enhanced Power & Torque

  The precision engineering of the LF155 piston ensures efficient conversion of combustion energy into mechanical power. Its aerodynamic crown design promotes optimal fuel-air mixing, leading to stronger acceleration (0-60km/h in 5.1 seconds, 13% faster than generic pistons), smoother power delivery, and higher top speed. Whether you’re overtaking on the road or climbing steep hills with a loaded tricycle, the LF155 piston delivers responsive performance that enhances the driving experience.

  Improved Fuel Efficiency

  By optimizing the compression ratio and ensuring tight sealing with the piston ring, the LF155 piston promotes complete fuel combustion. This reduces fuel consumption by up to 18% compared to worn or low-quality pistons, translating to significant cost savings for daily commuters and commercial tricycle operators. For example, a tricycle operator covering 180km daily can save up to $60 per month on fuel costs—adding up to $720 annually. Additionally, improved combustion lowers harmful emissions, making the LF155 piston an eco-friendly choice for engine parts.

  Reduced Wear & Extended Engine Life

  The LF155 piston’s low-friction coating and balanced design minimize wear on the cylinder wall and connecting rod. This not only extends the piston’s service life (up to 70,000km) but also protects other critical engine parts, reducing the risk of costly engine overhauls. By reducing friction and heat buildup, the piston ensures that your engine runs cooler and smoother, even during prolonged use.
