The cylindrical Liner provides the cylindrical space for smooth reciprocation. The Justification of the production of the Liner for the cylindrical block (jacket) is mentioned below. Superior material is used to produce the cylinder liner than the material used to manufacture the cylinder block. Grey cast iron is used to manufacture the cylinder block, while cylinder liner owes its origin to the cast iron alloy with chromium, vanadium, molybdenum. The combustion of the fuel must be increased, or the engine’s productivity must be escalated to increase the power of the machine. The capacity of the deflagration must be increased at the same time the inlet air for combustion must also be raised for the increased rate of burning fuel. A cylinder liner also called the sleeve, is used to form a cylinder in the engine block. It is one of the inevitable fundamental parts to add up to the engine’s interior, and protection from wear is also ensured for the piston and piston rings. The Liner is predicted to face increased temperature during the engine’s operation due to the conduction of the heat by burning the fuel to the walls of the cylinder. At operational temperature, the temperature of the Liner is comparatively higher than that of the block. The Diametrical and lengthwise expansion is likely to occur in the Liner relatively smooth. The fracture and collapse of the material are likely to happen if they were cast together as a single piece due to the unacceptable thermal stress. The Engine block must contain a cylindrical space for the piston to reciprocate smoothly. This is made sure with the help of a cylindrical liner in the engine block. The prime objective of this toil is to customize and study deeply the cylindrical Liner coated with Al2O3 Niño- material. In this work, ANSYS software has been used. The quantity of the generation of heat, the pace of heat transfer of the component, calefaction within the cylinder are identified in the pre-processing of the model. Further, the heat flux dissipation is analyzed, from which it is concluded that Niño based Al2O3 coated cylinder liner has performed adequately.
