It enables the small end of the connecting rod to drive the piston in motion. To reduce weight, piston pins are generally made of high-quality alloy steel and designed as hollow. Additional information: There are three methods of fixing the piston pin: 1. Using a floating pin, which can rotate in both the piston pin boss and the small end of the connecting rod. 2. The piston pin is fixed in the piston pin boss and can rotate in the small end of the connecting rod. 3. The piston pin is fixed in the small end of the connecting rod and can rotate in the piston pin boss.
