Basic functions of IC engine cylinder1) To retain the working fluid such as mixture of petrol and air or diesel and air2) To guide the piston
-Combustion of fuel takes place inside the Cylinder and therefore it is subjected to very hightemperature.-For this cooling arrangements are required
-In small engines- cylinder and frame are made ofOne-piece casting.-In large engines- a separate cylinder liner is used.
Construction details of cylinder liner
A thin cylinder may fail due to following stresses,1) Stress in tangential direction (Hoop stress) or circumferential stress 2) Longitudinal stress
** Hoop stress is twice the longitudinal stress hence design should be based on it.Thickness can be calculated as,
/ 2c i iPd t / 4l i iPd t
