Feed rate optimisation-fighting the cost of cold corrosion

摘要

Longer piston strokes in new generation, fuel-efficient engines can bring one such consequence: water condensation collects on the surfaces of cylinder liners, which reacts with sulphur dioxide in combustion gasses, leading to the formation of sulphuric acid and resulting in corrosion on the liner surface. The resulting iron compounds formed are flushed into the cylinder oil, leading to excessive wear of the cylinder liner.
