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

Cylinder Head

-
Cylinder head   provides a place for  combustion of the fuel/air mixture and to give the cylinder  more heat conductivity for adequate cooling. The fuel/air  mixture is ignited by the spark in the combustion chamber  and commences burning as the piston travels toward TDC  on the compression stroke. The  ignited charge is rapidly expanding at this time, and pressure  is increasing so that, as the piston travels through the TDC  position, it is driven downward on the power stroke. The intake and exhaust valve ports are located in the cylinder  head along with the spark plugs and the intake and exhaust  valve actuating mechanisms. After the cylinder head is cast, the spark plug bushings, valve  guides, rocker arm bushings, and valve seats are installed in  the cylinder head. Spark plug openings may be fitted with bronze or steel bushings that are shrunk and screwed into  the openings.                  Stainless steel Heli-Coil spark plug inserts   are used in many engines currently m

Cylinder -  The portion of the engine in which the power is developed  is called the cylinder provides  a combustion chamber where the burning and expansion of  gases take place, and it houses the piston and the connecting  rod.  Cylinder head of an air cooled engine is generally made of  aluminum alloy because aluminum alloy is a good conductor  of heat and its light weight reduces the overall engine weight. Cylinder heads are forged or die-cast for greater strength. The  inner shape of a cylinder head is generally semispherical.  The semispherical shape is stronger than conventionalist  design and aids in a more rapid and thorough scavenging of  the exhaust gases Cylinder used in the air cooled engine is the overhead  valve type.    Each cylinder is an assembly of two  major parts:   cylinder head and  cylinder barrel.  At assembly,  the cylinder head is expanded by heating and then screwed  down on the cylinder barrel, which has been chilled. When  the head cools an
