The gudgeon pin is another name for piston pins. It transfers the total generated power out of the combustion process from the piston through the connecting rod down to the crankshaft.
Function of Piston Pin
The piston pin creates a connection between the connecting rod and the piston. It has to withstand too high loads in changing direction. It is generally made up of nitrated or case hardening steel with a smooth ground, hardened, and polished surface.
It is essential to optimize the load-bearing capacity of this part of the engine permanently. It can withstand the producing loads out of the combustion process and the continuous increasing firing pressure.
The piston pins are characterized by precision, highest material quality, and application diversity. The piston is bent through, subjected to shear, and oval-shaped due to the ignition pressure's oscillating forces and the mass inertia forces within the opposite direction. The piston pin can be damaged by the extensive deformation, which can lead to the piston's destruction.
A cylinder liner is a thin metal cylinder-shaped part which is inserted within the engine block to create the inner wall of the cylinder.
Function of cylinder liner
The liner forms a sliding surface for the piston rings. It has high anti-galling properties. It is less wear on the partner positioned ring. It also helps the less consumption of lubricant. The cylinder liner receives combustion heat through the piston rings and the piston. It transfers heat to the coolant.
The cylinder liner helps to prevent the compressed gas and combustion gas from escaping outside. The cylinder liner must be hard to transform high temperature and pressure within the cylinder.
The mentioned above information will help you to get knowledge about the piston pins and cylinder liners. It will help you select the right options for them.
