Engine Piston Kit WP4.1G100E311 For WEICHAI WP4.1

Product Description:

• Our diesel engine piston is core power components manufactured for heavy-duty diesel machinery, including excavators, tractors, heavy trucks, loaders, diesel generators and marine engines. Produced strictly according to OEM dimensional standards, these pistons transmit combustion power efficiently while cooperating with piston rings, cylinder liners and crankshaft assemblies to maintain stable engine operation.
  We adopt high-silicon aluminum alloy as raw material, featuring lightweight structure, outstanding heat dissipation and high thermal deformation resistance. Precision machining and surface hardening treatment greatly improve wear resistance, effectively avoiding cylinder scratching, piston melting, power attenuation and oil burning failures under long-time high-temperature, heavy-load working conditions. Each piston is equipped with accurate pin holes, ring grooves and cooling inner cavities, realizing seamless matching with original engine parts for direct replacement during engine overhaul.

Key Features:

• High-Grade High-Silicon Aluminum Alloy Material
   
  Excellent heat conductivity and thermal stability, not easy to expand and deform under extreme high combustion temperature; strong anti-scuff performance to reduce cylinder wall abrasion.
• Precision CNC Machining & Standard Size
   
  All ring grooves, piston pin holes and outer diameters are precisely processed by digital lathes, fully consistent with OEM specifications. No grinding or trimming required for fast installation.
• Surface Reinforcement Treatment
   
  Tough anodized surface plus graphite coating on skirt area, lowering friction coefficient and eliminating dry friction noise, extending overall service life significantly.
• Built-In Internal Cooling Gallery
   
  Special cooling cavity design inside the piston head takes away combustion heat rapidly, preventing piston ablation and cracking for continuous heavy-duty operation.
• Strict Multi-Item Factory Testing
   
  Every finished piston undergoes dimensional tolerance test, hardness test and thermal expansion simulation test before delivery to eliminate defective products.
