Cylinder Liner with Piston Assy. form the heart of the engine and are very critical components for the running and for the performance of the engine. Care is to be taken for the correct size and also the correct material while producing this product.

Casting

The process starts by centrifugally casting the Cylinder Liner, which is the best process available and is reliable. Cast iron Alloy is poured into a die, which rotates at high speed resulting in a casted product. Good quality casting is very important for the quality of the Cylinder Liner. The Cylinder Liner's functional requirement is to be wear-resistant (not to be worn cut easily). It should have strength, and hardness but not too hard. Very hard liner will become brittle (and break) and may chip off easily. The Cylinder Liner should have all the properties of wear resistance, strength, hardness, toughness, corrosion resistance, no blow holes, a fine grain structure, etc. The casting Alloy should be low in Sulpher. The Alloy should have carbon in a controlled percentage plus Silicon, Chromium, Manganese, Molybdenum, and Nickel along with other elements to make a good quality casting.

Machining

The next step is to machine the casting. Operation of turning, phasing, and boring are done to accurate size. Care is also taken for an even wall thickness of the Cylinder Liner. The last operation is bore horning, which we do on Hydraulic Vertical horning - double expansion machine to achieve R.A. values. The cross-horning lines are important to retain an oil film in the Cylinder Liner. Not too much oil film (or the engine will give smoke) and not less (or it will become hot and also wear out very fast). We at Reliable Engg House understand what is a good Cylinder Liner and that is why our products are successful.
