An approximate normal cylinder liner wear rate is about 0.1 mm per 1000 running hours. The wear rate increases if the engine is overloaded. Generally, the liner has to be replaced when the cylinder liner wear rate is about 0.6-0.8% of the bore diameter or as per the manufacturer’s recommendation. See more The wear in the cylinder liner is mainly because of following reasons:- 1) Due to friction. 2) Due to corrosion. 3) Abrasion 4) Scuffing or Adhesion See more Whenever two surfaces slide over each other, friction is produced which leads to wearing down of both the surfaces. In liner wear, the surfaces are piston rings sliding over the cylinder … See more Cylinder wear can be minimised by carrying out the following steps: 1) By avoiding any ingress of water inside the liner by properly treating the fuel oil. 2) By maintaining the correct grade of cylinder oil. 3) By supplying … See more The cylinder liner wear due to corrosion is caused due to these reasons: – Burning of heavy fuel oil in the combustion space: This happens because heavy fuel oil contains high sulfur content.
