Product Features
  • Cast Iron Ring Carrier & Advanced Crown Swirl Geometry: Features a Ni-Resist cast iron insert bonded into the top ring groove to prevent groove wear and micro-welding under severe thermal stress. The precision-machined piston crown geometry optimizes fuel-air swirl mixing, delivering enhanced combustion efficiency and reduced exhaust emissions.
  • Thermal-Expansion Alloy & Heavy-Duty Skirt Structure: Cast from a high-silicon aluminum alloy that offers excellent thermal conductivity and low expansion rates. The skirt is engineered with a micro-tapered profile and anti-friction coating, maintaining ideal clearance with the 102 mm cylinder liner across temperatures while mitigating skirt slap and friction losses. 
  • Graphite-Coated Friction Barrier & Reinforced Pin Bore: The piston pin bore is heavy-duty reinforced and polished to withstand peak firing pressures without deformation. A protective graphite coating applied to the outer skirt provides critical boundary lubrication during dry cold starts, preventing premature scuffing or seizure against the liner.
