Key Specification

Thefunction ofthe pistonis exposed tothe gaspressure, andto passthrough the piston pin to theconnecting rod driven bythe rotation of thecrankshaft, thepiston top oran integral part of the combustion chamber. Working conditions pistonworking ina high-temperature,high-pressure, high-speed, poor lubricationconditions. Piston directly in contact with the high temperature gas instantaneoustemperature up to 2500K,therefore, serious heat,and poorcooling conditions,the pistonwork at hightemperatures, upto 600to 700Kat the top and thetemperature distribution is veryuneven; top of thepiston is exposed to gas pressure,especially for the power stroke pressureof up to 3to 5 MPa, gasoline, diesel engine up to6 to 9MPa, whichmakes the piston animpact, andto withstand theside pressure of therole; pistonwithin the cylinder athigh speed (8 12m / s)reciprocating motion, and the speed is constantlychanging, which produce a great deal of inertia force,the piston is subjected to a great deal of additional load.The pistonwork undersuch harsh conditions, will produce a deformation and accelerated wear,but also produce the additional load and thermalstress, andat the same time bythe chemical etching effect of the gas.
