Modern slow speed, two stroke diesel engines often have locating pins or pegs to keep the piston rings in a fixed position. Why is this arrangement used?
It ensures the rings cannot be mixed up and that they are fitted in the correct order on the piston.

The piston ring gaps can be kept in line to control the gas pressure on each of the rings.
The piston rings are more difficult to lubricate because of the slow operating speeds and will wear more quickly if they are allowed to rotate.
