Cylinder liners

The main function of the cylinder liners is to seal the combustion chamber, allowing the thermal exchange of heat throughout the block. Its use allows the reuse of the block, maintaining its useful life.

Did you know?

Just like the other parts developed and produced by RIO for the spare parts market, the cylinder liners have the guarantee of quality and perfect geometry. This happens because the liners for engine cylinders are produced in a centrifugation process monitored by cutting-edge equipment and machined on CNC machines of great dimensional precision.

According to the service manuals, the interference between the cylinder liner and its respective housing must be between 0,04 and 0,06 millimeters (light line) and between 0,06 and 0,08 millimeters (heavy line).
