The cylinder is the enclosed space in which the mixture of air and fuel is burned and then heat energy transformed to mechanical energy. A cylinder may be constructed of a varying number of parts among which the essentials are the cylinder jacket, the cylinder liner, and the cylinder head. In most designs the space between the cylinder jacket and the liner is cored to carry circulating water for cooling purposes.
