Ductile cast iron Piston ring 4G18-2 4G18 Alloy cast iron Piston rings MD361982 MD349422

SPECIFIIONS:

The force acting on the piston ring is the gas pressure,the ring's own elastic force,the inertial force of the ring reciproing 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.

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.

AIR TIGHTNESS:

The first function of the piston ring is to maintain a seal between the piston and the cylinder wall to control leakage to a minimum.This effect is mainly borne by the gas ring,that is,the engine is controlled to minimize the leakage of compressed air and gas under any operating conditions to improve the thermal efficiency:to prevent the cylinder and the piston or the cylinder and the ring from being caused by the air leakage.Killing:preventing malfunction caused by deterioration of lubriing oil,and the like.

OIL CONTROL:

The second function of the piston ring is to properly scrape off the oil adhering to the cylinder wall and maintain normal fuel consumption.When the supplied lubriing oil is excessive,it will be sucked into the combustion chamber to increase the fuel consumption,and the carbon deposit generated by the combustion has a very bad influence on the engine performance.
