I. Piston

1, function: withstand gas pressure, and through the piston pin and connecting rod to drive the crankshaft rotation: the top of the piston and the cylinder head, cylinder wall together to form the combustion chamber.

2. Working environment

High temperature, poor heat dissipation conditions; The working temperature of the top is as high as 600~700K, and the distribution is not uniform: high speed, the linear speed is up to 10m/s, under great inertia force. The top of the piston is subjected to the maximum pressure of 3~5MPal(gasoline engine), which causes it to deform and break the fit connection

Piston top 0 function: is a component of the combustion chamber, the main role to withstand gas pressure. The shape of the top is related to the shape of the combustion chamber

Position of piston head (2) : The part between the next ring groove and the piston top

Function:

1. Transfer the pressure on the top of the piston to the connecting rod (force transmission). 2. Install the piston ring and seal the cylinder together with the piston ring to prevent the flammable mixture from leaking into the crankcase

3. Transfer the heat absorbed by the top to the cylinder wall through the piston ring

Piston skirt

Position: From the lower end of the oil ring groove to the bottom part of the piston, including the pin seat hole. And bear lateral pressure. Function: to guide the reciprocating movement of the piston in the cylinder,
