Summary[edit]
Description47mm piston rings.jpg |
A pair of en:piston rings mounted on a 47 mm en:piston. Note the use of a pin to prevent the piston rings rotating around the piston. This is a feature of piston-ported engines, most of which (and for those 47 mm diameter, we can assume all of them) are two-strokes. Picture taken and released into the en:public domain by en:User:Kallemax. |
