Features:

Composite polyurethane material, high impact resistance, high elasticity, high wear resistance, long service life.

Pistons are the "heart" of automobile engines. They are subjected to alternating mechanical and thermal loads and are one of the most critical parts in the engine's worst working conditions. The function of the piston is to withstand the pressure of the gas, and transmitted to the connecting rod through the piston pin to drive the crankshaft. The top of the piston is also a part of the combustion chamber.
The types of pistons are generally divided into: diesel vehicle pistons, gasoline vehicle pistons, and universal pistons
