Why piston pin is designed offset?

The piston pin is designed offset to accommodate the forces exerted during the engine's operation and to optimize the performance of the engine. By positioning the pin off-center, it helps reduce side loading on the piston, which minimizes friction and wear on the cylinder walls. This offset also aids in achieving a more uniform distribution of combustion forces, enhancing engine efficiency and longevity. Additionally, it can contribute to improved engine balance and reduced noise and vibration.
