It is in direct contact with engine block. The outer diameter is very precise and perfect without
contours.In passenger cars and smaller utility vehicle engines, dry cylinder liners are used wherever the material of the engine block does not satisfy the tribological requirements.

The sealing rings and tombak shims are included in the scope of supply for the cylinder liners.
