Connecting Rod

-
Connecting rod is the link that transmits forces between
the piston and the crankshaft is strong enough to remain rigid under load and yet be light enough to reduce the inertia forces that are produced when the rod and piston stop, change direction, and start
again at the end of each stroke.
There are four types of connecting-rod assemblies 
1. Plain
2. Fork and blade
3. Master and articulated
4. Split-type

Cylinder Barrel

Cylinder barrel   are  made of light and high-strength material and  have the proper characteristics for  operating under high temperatures. It must be made of a  good bearing material and have high tensile strength.  Cylinder barrel is made of a steel alloy forging with the inner  surface hardened to resist wear of the piston and the piston  rings which bear against it.  Hardening is usually done  by exposing the steel to ammonia or cyanide gas while the steel is very hot. The steel soaks up nitrogen from the gas,which forms iron nitrides on the exposed surface. As a result  of this process, the metal is said to be nitrided.  Nitriding   only penetrates into the barrel surface a few thousands of an  inch. As the cylinder barrels wear due to use, they can be  repaired by chroming. This is a process that plates chromium  on the surface of the cylinder barrel and brings it back to new  standard dimensions.  Chromium-plated cylinders should use  cast iron rings. Honing the cyli
