What is the purpose of piston rings?

Piston rings create a seal between the piston and the cylinder wall. This seal is essential for maintaining compression within the cylinder and preventing oil from entering the combustion chamber.

What do the different ring sizes (1.2mm, 1.2mm, 3.0mm) mean?

These measurements refer to the thickness of each ring in millimeters. The top and second rings are 1.2mm thick, while the oil control ring is 3.0mm thick. This specific sizing is important for proper fitment on the piston and effective sealing within the cylinder bore.
