Cylinder Liner with Piston Assy. form the heart of the engine and are very critical components for the running and for performance of the engine. Care is to be taken for correct size and also correct material while producing this product.
The process starts by centrifugally casting the Cylinder Liner, which is the best process available and is reliable. Cast iron Alloy is poured in to a die, which rotates at high speed resulting into a casted product. A good quality casting is very important for the quality of the Cylinder Liner. The Cylinder Liner functionally requirement is to be wear resistant (not to be worn cut easily). It should have strength, 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 resistant, no blow holes, a fine grain structure etc. The casting Alloy should be low in Sulpher. The Alloy should have carbon in controlled percentage plus Silicon, Chromium, Manganese, Molybdenum, Nickel along with others elements to make a good quality casting.
The next step is to machine the casting. Operation of turning, phasing, 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 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.
