Product Description
Piston 3804747 is a forged high-silicon aluminum piston for turbocharged diesel engines, widely used for overhaul of construction machinery and vehicle-mounted power units. It has five core features:
- Diversion rib design inside combustion bowl. Guide ribs split fuel spray airflow and spread fuel evenly for direct injection. It achieves complete combustion under variable loads, restricts peak heat and reduces thermal fatigue damage.
- Silicon infiltration hardening on ring grooves. The groove surfaces are reinforced by silicon permeation treatment. It improves surface hardness and wear resistance against repeated friction from piston rings, slows groove deformation and maintains sealing performance to reduce gas blow-by.
- Gradient oil grooves on piston skirt. Progressive micro grooves capture lubricant during piston travel and form a continuous oil film on liner wall. It relieves boundary friction under heavy load and greatly reduces cylinder scuffing risk.
- Offset pin bore for impact damping. Slightly offset wrist pin hole adjusts the timing of piston slap. It cuts side thrust against the cylinder liner and lowers mechanical noise under continuous vibration on job sites.
- Tolerance sorting inspection for finished parts. Combustion bowl volume, skirt profile and pin bore concentricity are checked one by one. Pistons are grouped by weight to keep minimal weight difference, ensuring smooth engine operation and less vibration.
This interchangeable aftermarket piston can be supplied separately or as a complete kit with piston pin, circlips and piston rings. When installed with cylinder liner assemblies, it delivers stable durability under fluctuating heavy loads at construction and quarry sites
