| piston |
The piston is a reciprocating part in the cylinder block of an automobile engine |
| Working conditions |
The piston works under high temperature, high pressure, high speed and poor lubrication. The piston directly contacts with high-temperature gas, and the instantaneous temperature can reach more than 2500K. Therefore, the piston is seriously heated and the heat dissipation condition is very poor, so the temperature of the piston is very high when it is working, and the top is up to 600-700K, and the temperature distribution is very uneven; The top of the piston bears great gas pressure, especially the pressure of the work stroke, which is as high as 3~5MPa for gasoline engines and as high as 6~9MPa for diesel engines. This makes the piston impact and bear the effect of side pressure; The piston moves back and forth at a high speed (8~12m/s) in the cylinder, and the speed is constantly changing, which generates a large inertial force and makes the piston subject to a large additional load. When the piston works under such harsh conditions, it will deform and accelerate wear, generate additional load and thermal stress, and be subject to chemical corrosion of gas. |
