What are the functions of piston, piston ring and piston pin?
The main role of the piston is to withstand the force generated by the gas pressure in the cylinder, and pass this force to the connecting rod through the piston pin, driving the crankshaft to rotate. The piston top also forms the combustion chamber with the cylinder head and cylinder wall. The piston is driven by a connecting rod to complete three auxiliary strokes: intake, compression and exhaust. The piston ring comprises a gas ring and an oil ring.

The main role of the piston is to withstand the gas pressure in the cylinder and pass this pressure to the connecting rod through the piston pin to push the crankshaft to rotate. The top of the piston also forms the combustion chamber together with the cylinder head and the cylinder wall. The piston ring is installed in the piston ring groove, and the piston ring includes two kinds of gas ring and oil ring.

The role of the piston pin is to connect the small head of the piston and the connecting rod, and transfer the air force of the piston to the connecting rod.

The piston ring is installed in the piston ring groove to seal the gap between the piston and the cylinder wall, prevent gas channeling, and make the reciprocating movement of the piston smooth. Piston rings are divided into gas rings and oil rings. Piston pin The role of the piston pin is to connect the piston and the connecting rod small head, and to transfer the gas force of the piston to the connecting rod.

The two at the top of the piston are gas rings, also known as compression rings. Its role is to seal the cylinder to prevent air leakage, and it has a role is to transfer the heat from the top of the piston to the cylinder liner, and the cooling water takes away the heat.
