1,Precise fit:These pistons are tailor-made for the excavator 3306DT engine. Its dimensional accuracy is extremely high, and the engine cylinder inner diameter, connecting rod size and other parameters are closely matched. 
2,High wear resistance:Considering the harsh working environment and high working intensity of excavator engines, these pistons are made of materials with excellent wear resistance.
3,High strength structure:The excavator engine will be subjected to great pressure and impact force during operation, and these pistons are designed to cope effectively. Their internal structure is optimized, for example, the top of the piston can withstand the high temperature and high pressure gas pressure in the combustion chamber.
4,Optimized power performance:The shape and design details of the piston have an important impact on the engine's power output and fuel efficiency. The top shape and finish of these pistons help fuel atomize and mix better in the combustion chamber for fuller combustion.
