Product Description

Piston 3802474 is a cast high-silicon aluminum piston for turbocharged diesel engines, widely used for overhaul of large construction machinery and mining power equipment. It has five core features:

  1. Curved constricted combustion bowl. The narrowed rounded opening controls fuel spray spread and builds orderly swirl for direct injection. It stabilizes peak combustion temperature and minimizes carbon deposits from incomplete combustion.
  2. Stress-released transition at groove root. Smooth rounded corners remove sharp stress points. It resists crack initiation under thermal expansion and repeated ring friction, preserving groove geometry and reliable cylinder sealing over long service hours.
  3. Bi-curved skirt profile for thermal compensation. The skirt contour is engineered for thermal expansion. It maintains proper clearance when cold and uniform contact with liner at operating temperature, eliminating piston slap and scuffing risk.
  4. Wedge oil guide grooves at pin bore ends. Angled internal grooves feed lubricant into the clearance between pin and bore. A dynamic oil film absorbs reciprocating impact and slows wear of the pin joint.
  5. Closed-loop inspection and sorting workflow. Combustion depth, pin bore concentricity and skirt profile are fully verified. Pistons are sorted by strict weight tolerance to limit imbalance and reduce engine vibration.

This interchangeable aftermarket piston is available individually or as a full set with piston pin, circlips and piston rings. When assembled with cylinder liner kits, it delivers stable durability under fluctuating heavy loads on outdoor job sites.
