How Piston Ring works

Piston rings commonly used on engines include the compression ring, wiper ring, and oil ring. The compression ring is the top or closest ring to combustion gases. And it is exposed to the greatest amount of chemical corrosion and the highest operating temperature. The piston rings carry heat away from the hot piston into the cooled cylinder wall/block of the engine. Heat energy flows from the piston groove into the piston ring and then into the cylinder wall. It eventually will be transferred into the engine coolant.

BOSKET Industrial Ltd.professionally provides piston rings for various Japanese Trucks such as:
