CYL DIA (Cylinder Diameter): 56.5mm – Optimizes displacement for maximum torque output, while maintaining a tight, leak-proof seal with the cylinder wall to enhance combustion efficiency and power delivery.
TOTAL HIGH (Total Height): 55mm – Increased height enhances structural rigidity, supporting the piston’s ability to withstand high combustion pressures and heavy loads (up to 680kg) without deformation.
COMP DIST (Compression Distance): 26mm – Fine-tunes the engine’s compression ratio for balanced power and fuel efficiency, ensuring responsive acceleration across all RPM ranges—critical for both riding and hauling.
Piston Ring Specifications: 1.21.22.5mm – Heavy-duty triple-ring configuration (two compression rings + one oil control ring) with thick cross-sections delivers superior sealing, reduces oil consumption, and prevents carbon buildup in high-heat, high-cycle operation.
PIN DIA (Piston Pin Diameter): 15mm – Reinforced pin diameter provides exceptional load-bearing capacity, ensuring stable power transmission to the connecting rod even under extreme stress.
PIN LENGTH (Piston Pin Length): 47.5mm – Extended length distributes load evenly across the connecting rod, minimizing wear and extending the piston’s service life in heavy-duty scenarios.
Extreme Durability: Resists corrosion, mechanical fatigue, and thermal expansion, extending the piston’s service life to 90,000km—ideal for commercial operators seeking long-term reliability and reduced replacement costs.
Enhanced Heat Management: Efficiently dissipates heat generated by heavy-duty operation, preventing engine overheating—a common concern for tricycle operators and riders in high-temperature environments.
Consistent Performance: Maintains dimensional precision over time, ensuring stable torque output and fuel efficiency even after years of high-cycle use.
Raw Material Testing: Ensures the 2017A aluminum alloy meets aerospace-grade standards for strength and heat resistance.
Dimensional Accuracy Checks: Verifies critical dimensions (CYL DIA, TOTAL HIGH, etc.) using laser measuring tools to match the TY125’s exact tolerances.
Pressure & Fatigue Testing: Simulates the TY125’s operating conditions (up to 16.5 bar pressure and 15,000 cycles) to assess sealing performance and resistance to mechanical fatigue.
Ring Groove Precision Checks: Ensures the piston’s ring grooves are machined to exact specifications, guaranteeing a tight fit with the thick piston ring set and preventing oil leakage.
