Advantages:
1.High strength structure design
Made of cast iron or aluminum alloy material, with excellent compressive and deformation resistance, suitable for high load conditions.
2.Durability and wear resistance
The inner wall of the cylinder is specially treated (such as honing process) to reduce friction loss and extend service life.
3.Heat dissipation performance optimization
The reasonable water channel layout design ensures that the heat is evenly distributed during engine operation to avoid local overheating.
4.Precision machining technology
The precision of cylinder block and crankshaft, piston and other components is high, which improves the overall performance and stability of the engine.
5.Lightweight and compact
Aluminum alloy material can reduce the weight of the whole machine, while optimizing the space layout, suitable for a variety of equipment requirements.
6.Reliable sealing performance
The seal structure of the cylinder block and cylinder head is strictly designed to effectively prevent coolant and oil leakage.
7.Maintenance convenience
The modular design may facilitate the removal and replacement of internal components, reducing maintenance costs.
8.Wide adaptation
As the core component of mature models, it is compatible with a variety of construction machinery or generator sets.
