The function of the piston is to withstand the gas pressure and transmit it to the connecting rod through the piston pin to drive the crankshaft to rotate. The top of the piston is also an integral part of the combustion chamber. Working conditions The piston works under the conditions of high temperature, high pressure, high speed and poor lubriion. The piston is directly in contact with the high-temperature gas, and the instantaneous temperature can reach above 2500K. Therefore, the heat is severe and the heat dissipation conditions are poor, so the temperature of the piston is very high when it is working, and the top is as high as 600-700K, and the temperature distribution is very uneven; the top of the piston bears The gas pressure is very high, especially the power stroke pressure is the highest, the gasoline engine is as high as 3-5MPa, and the diesel engine is as high as 6-9MPa, which makes the piston produce impact and bear the effect of side pressure; the piston moves in the cylinder at a very high speed (8 ~12m/s) reciproing motion, and the speed is constantly changing, which produces a large inertial force, which makes the piston subject to a large additional load. Working under such harsh conditions, the piston will deform and accelerate wear, as well as generate additional load and thermal stress, and at the same time be subjected to chemical corrosion by gas
