An internal combustion engine;
- comprising:
- a combustion chamber having a bore wall;
- a piston configured to move relative to the bore wall;
- and
- a plurality of piston rings provided to the piston, each of the piston rings having a main body that is circular, each of the pistons rings further having a stopper that protrudes from the main body,
- the plurality of piston rings including a first ring that is a seal ring,
