Description
Main Parts of an Internal Combustion Engine Below:
Piston
The first, a piston is fitted to each cylinder as a face to receive gas pressure and transmit the thrust to the connecting rod. It is a prime mover in the engine. The main function of piston is to give tight seal to the cylinder through bore and slide freely inside the cylinder. Piston should be light and sufficient strong to handle gas pressure generated by combustion of fuel. So the piston is made by aluminum alloy and sometimes it is made by cast iron because light alloy piston expands more than cast iron so they need more clearances to the bore.
Connecting rod
The
second,
Connecting
rod
connects
the
piston
to
crankshaft
and
transmits
the
motion
and
thrust
of
piston
to
crankshaft.
It
converts
the
reciprocating
motion
of
the
piston
into
rotary
motion
of
crankshaft.
There
are
two
end
of
connecting
rod;
one
is
known
as
big
end
and
other
as
small
end.
Big
end
is
connected
to
the
crankshaft
and
the
small
end
is
connected
to
the
piston
by
use
of
piston
pin.
The
connecting
rods
are
made
of
nickel,
chrome,
and
chrome
vanadium
steels.
For
small
engines
the
material
may
be
aluminum.
Main
Parts
of
an
Internal
Combustion
Engine
(connecting
rod)
Crankshaft
Thirdly,
the
crankshaft
of
an
internal
combustion
engine
receives
the
efforts
or
thrust
supplied
by
piston
to
the
connecting
rod
and
converts
the
reciprocating
motion
of
piston
into
rotary
motion
of
crankshaft.
The
crankshaft
mounts
in
bearing
so
it
can
rotate
freely.
The
shape
and
size
of
crankshaft
depends
on
the
number
and
arrangement
of
cylinders.
It
is
usually
made
by
steel
forging,
but
some
makers
use
special
types
of
cast-iron
such
as
spheroidal
graphitic
or
nickel
alloy
castings
which
are
cheaper
to
produce
and
have
good
service
life.
