Description
Main Parts Of Engine Below:
Engine bearing
Everywhere there is rotary action in the engine, bearings are
needed. Bearings are used to support the moving parts. The
crankshaft is supported by bearing. The connecting rod big end is
attached to the crank pin on the crank of the crankshaft by a
bearing. A piston pin at the small end is used to attach the rod to
the piston is also rides in bearings.
The main function of bearings is to reduce friction between these
moving parts. In an IC engine sliding and rolling types of bearing
used. The sliding type bearing which are sometime called bush is
use to attach the connecting rod to the piston and crankshaft. They
are split in order to permit their assembly into the engine. The
rolling and ball bearing is used to support crankshaft so it can
rotate freely. The typical bearing half is made of steel or bronze
back to which a lining of relatively soft bearing material is applied.
Main Parts of an Internal Combustion Engine (engine bearing)
Crankcase
The main body of the engine at which the cylinder are attached and
which contains the crankshaft and crankshaft bearing is called
crankcase. It serves as the lubricating system too and sometime it
is called oil sump. All the oil for lubrication is placed in it.
Main Parts of an Internal Combustion Engine (crankcase)
Valves
To control the inlet and exhaust of internal combustion engine,
valves are used. The number of valves in an engine depends on the
number of cylinders. Two valves are used for each cylinder one for
inlet of air-fuel mixture inside the cylinder and other for exhaust
of combustion gases. The valves are fitted in the port at the
cylinder head by use of strong spring. This spring keep them
closed. Both valves usually open inwards.
