Piston Connecting Rod

A piston connecting rod, also known as a connecting rod or conrod, is a crucial component in an internal combustion engine. It connects the piston to the crankshaft and converts the reciprocating motion of the piston into rotational motion of the crankshaft.

The piston connecting rod is typically made of high-strength steel or aluminum alloy to withstand the high forces and temperatures generated within the engine. It consists of two main parts: the small end and the big end.

The small end of the connecting rod is attached to the piston pin, which connects the piston to the connecting rod. The small end is usually equipped with a bronze bushing or needle bearing to reduce friction and allow for smooth movement.

The big end of the connecting rod is attached to the crankshaft through a bearing known as the connecting rod bearing. This bearing allows the connecting rod to pivot and rotate around the crankshaft journal, enabling the conversion of linear motion to rotational motion.

The piston connecting rod plays a vital role in the engine's operation by transferring the force generated by the combustion process from the piston to the crankshaft. It must be strong and durable to withstand the high pressures and forces exerted during engine operation.

Overall, the piston connecting rod is an essential component in the internal combustion engine, ensuring the efficient conversion of reciprocating motion to rotational motion, ultimately powering the vehicle or machinery.
