12040-90025 Diesel Engine Piston Ring Set NISSAN PE6

The force acting on the Piston Ring is the gas pressure,the ring's own elastic force,the inertial force of the ring reciprocating motion,the friction between the ring and the cylinder and the ring groove,as shown in the figure.Due to these forces,the ring will produce basic motions such as axial motion,radial motion,and rotary motion.In addition,due to its motion characteristics,the piston ring is accompanied by irregular movement,and inevitably,floating and axial vibrations caused by axial irregular motion,radial irregular motion and vibration,twisting motion,and the like are inevitable.These irregular movements often prevent the piston ring from functioning.When designing the piston ring, it is necessary to give full play to the favorable movement and control the unfavorable side.

2.Thermal conductivity:

The high heat generated by the combustion is transmitted to the cylinder wall through the piston ring,so that it can function as a cooling piston.The heat radiated from the piston ring to the cylinder wall can generally reach 30-40% of the heat on the top of the piston.

Advantages

1.The surface of piston ring has oxide film, with corrosion resistance, anti-wearlubrication and good appearance.
2.Chrome plated layer, good wear resistance and storage lubricating oil
3.Nitriding treatment, with good wear resistance and corrosion resistance
4.Spring ptfe process, friction coefficient is very low, excellent lubricity.
