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.
It avoids the risk of the ends of the piston rings being forced out by the gas pressure and catching on the scavenge ports.
