Product Overview
4022533X Engine Piston (PISTON,ENGINE) is the core moving component of Cummins series diesel engine combustion chamber. Installed inside engine cylinder liner, it bears high pressure from fuel combustion, converts gas expansion force into mechanical power, and transfers power to crankshaft through connecting rod.
This piston solves serious engine faults including piston crown ablation, skirt scuffing, ring groove wear, power decline and blow-by caused by overloading, high temperature aging and abrasion of old pistons, which is a key spare part for engine major overhaul.
Core Product Advantages
High Performance Heat Resistant Alloy Material
Special high-strength piston alloy material, excellent thermal conductivity and anti-thermal fatigue performance, withstand instantaneous high temperature and high pressure inside cylinder without cracking or melting loss.
Precision Machined Ring Grooves
Accurately processed piston ring grooves, ensure perfect fit with piston rings, effectively control engine oil consumption and prevent gas blow-by from combustion chamber.
Optimized Piston Skirt Profile
Fine finished skirt surface with reasonable profile design, form stable lubricating oil film, reduce friction with cylinder liner and avoid cylinder scuffing.
Precision Pin Bore Machining
High tolerance piston pin hole, guarantee stable matching with piston pin, reduce impact wear during reciprocating movement.
Wide Temperature Adaptability
Stable structural performance under drastic temperature changes inside cylinder, resist thermal deformation under long-term high-load continuous operation.
Standard Matching Specification
Dimension 19cm15cm15cm, weight 3.162KG, perfectly match Cummins engine cylinder assembly, direct replacement without extra machining.
Strict Factory Multi-Process Inspection
All pistons pass dimensional inspection, hardness testing and thermal stability detection, stable batch quality for engine overhaul factories and large transport fleets bulk procurement.
