Piston rings commonly make the minimum lubricating oil film necessary to prevent scuffing. To function as a scraper and oil control to prevent excessive consumption of oil that could result if lubricant is allowed to leak past into the combustion chamber. Piston rings transfer heat from the piston crown to the cylinder Wall.
The piston rings are fixed into the grooves of the piston to maintain a good seal between the piston and the cylinder wall. To provide a pressure seal to prevent blow-by of burnt gases. Blow-by is the name that defines the exhaust of burnt gases from the combustion chamber, through the piston, and into the crankcase.
