Piston 3802263 is cast aluminum piston for turbocharged diesel engines, widely used for overhaul of construction machinery and generator sets. It has five core features:
- Multi-step recessed combustion bowl. The stepped bowl restricts the spread of fuel spray for direct injection combustion. Stable fuel mixture is formed under varied loads to suppress knocking and deliver gentle combustion.
- Stress relief groove under ring grooves. Tiny relief slots at the bottom of each groove release concentrated thermal stress. It prevents groove cracking and deformation, maintains piston ring sealing and reduces gas blow-by.
- Variable curvature skirt profile. The uneven curved skirt compensates thermal expansion automatically. It keeps proper clearance between piston skirt and liner, avoiding piston slap at cold start and scuffing under high temperature.
- Lubrication grooves at pin bore ends. Annular oil grooves inside the wrist pin hole reserve lubricant. A persistent oil film is formed during reciprocating movement, reducing dry friction between pin and bore.
- Grouped inspection with full dimension check. Combustion depth, skirt contour and pin hole concentricity are verified one by one. Pistons are sorted by weight to limit weight difference, minimizing engine vibration during operation.
This aftermarket piston has great interchangeability. It is available individually or as a kit with piston pin, circlips and rings. When assembled with cylinder liner kits, it provides stable and durable performance under variable outdoor working loads.
