Engine Cylinder

The cylinder is the central working part of reciprocating engine, the space in which a piston travels. Multiple cylinders are commonly arranged side by side in a bank, or engine block. It is usually cast from iron or aluminium before more details are featured on it. Then, it is also lined with sleeves or liners of a harder metal. The piston are placed in it so that the cylinder must be made from the high melting point material because the combustion of engine occurs in it. That is why we use cast iron or aluminium to made this part. To make this part, different cooling rates sufficient to produce different properties in materials are produced by varying the surface to volume ratio and the sectional thickness of at least two of the component zones so as to cause cooling to be different in the zones when the cast metal is allowed to cool in the mold during the casting process.The cylinder is the central working part of reciprocating engine, the space in which a piston travels.
