Description

Piston rings are used to separate the combustion chamber from the crankcase; they are also used to regulate the amount of lubrication oil between the cylinder liner and piston. Piston rings maintain a seal between the combustion space and crankcase. The combustion space comprises a fixed cylinder wall and a fixed upper wall. As it is not possible to have a fixed lower wall, piston rings are used to form a moving seal. Piston rings are attached to the piston within recessed groves and a thin film of oil fills the space between the rings and cylinder liner (the piston rings do not touch the liner). Due to the oil film and fine clearances between the rings and liner, the rings are able to maintain a tight seal despite traveling linearly up and down within the cylinder.
