Effect’s of Heat Stress in Cylinder Walls

Effect’s of Heat Stress in Cylinder Walls Points : effect’s of heat stress in cylinder walls, causes of heat stress in cylinder walls, ic engine problems relating to engine cylinder In the reciprocating internal-combustion engine, temperature of lit gases in the cylinder varies from 100°F less to as high as 5000°F during each cycle. Owing to their very high temperature the cylinder would soon become too hot causing piston seizure.

Direct damage due to excessive cylinder wear arid even cracked cylinder bocks is evident due to the heat stress. There is now better positioning and dimensioning of the water passage in the cylinder bock and head, allowing a free flow of cooling water.

The rate of wear on the cylinder bone is largely dependent on the design of the engine, the metal used and the type a piston and rings employed. Wear does not take place on the pistons to the same extent as in the cylinder bores is continual rubbing on the cylinder bore walls is accelerated by the necessary radial pressure inherent in the ring itself.

Consequently the face of the ring gradually wears which, coupled with wear of cylinder bore reduces the scaling qualities necessary for good compression. Coupled with this, wear block are distorted to any appreciable extent even a soft copper asbestos gasket is unlikely to maintain a sound in.
