The connecting rod is a component of most engines used to link the piston to the crankshaft. The small end (end towards the piston) is usually connected through the use of a wrist pin whereas the big end mates to the crankshaft with a bearing. The connecting rod translates the linear motion of the piston in the cylinder to the rotational motion of the crankshaft.
