The function of the gas piston is under pressure to pass through the connecting rod piston pin crankshaft driven piston, the top part of the combustion chamber. Pistons at high temperature, high pressure, high-speed, work under poor lubrication conditions. Direct contacts with the hot gas piston, the instantaneous temperature up to 2500K or more, so, serious heat, and cooling terms and conditions are very poor, so the piston working temperature is high, the top up to 600 ~ 700K, and the temperature distribution is very uneven; piston under the Ministry of the gas pressure, in particular, the greatest pressure for power stroke, gasoline up to 3 ~ 5MPa, diesel engines up to 6 ~ 9MPa, which makes an impact piston and the role of lateral pressure to bear; piston in the cylinder at high speed (8 ~ 12m / s) reciprocating motion, and the speed is constantly changing, which creates a lot of inertia, so that the additional load of the piston has been greatly. Pistons in this work under harsh conditions, will produce distortion and accelerated wear, but also generate additional load and thermal stress, while the chemical corrosion by the gas .
