Main Parts of an Internal Combustion Engine:
Cylinder head
The
top
end
of
the
engine
cylinder
is
closed
by
means
of
removable
cylinder
head.
There
are
two
holes
or
ports
at
the
cylinder
head,
one
for
intake
of
fuel
and
other
for
exhaust.
Both
the
intake
and
exhaust
ports
are
closed
by
the
two
valves
known
as
inlet
and
exhaust
valve.
The
inlet
valve,
exhaust
valve,
spark
plug,
injector
etc.
are
bolted
on
the
cylinder
head.
The
main
function
of
cylinder
head
is
to
seal
the
cylinder
block
and
not
to
permit
entry
and
exit
of
gases
on
cover
head
valve
engine.
Cylinder
head
is
usually
made
by
cast
iron
or
aluminum.
It
is
made
by
casting
or
forging
and
usually
in
one
piece.
Main
Parts
of
an
Internal
Combustion
Engine
(cylinder
head)
Piston rings
A
piston
must
be
a
fairly
loose
fit
in
the
cylinder
so
it
can
move
freely
inside
the
cylinder.
If
the
piston
is
too
tight
fit,
it
would
expand
as
it
got
hot
and
might
stick
tight
in
the
cylinder
and
if
it
is
too
loose
it
would
leaks
the
vapor
pressure.
To
provide
a
good
sealing
fit
and
less
friction
resistance
between
the
piston
and
cylinder,
pistons
are
equipped
with
piston
rings.
These rings are fitted in grooves which have been cut in the piston. They are split at one end so they can expand or slipped over the end of piston. A small two stroke engine has two piston rings to provide good sealing but a four stroke engine has an extra ring which is known as oil ring. Piston rings are made of cast iron of fine grain and high elastic material which is not affected by the working heat. Sometimes it is made by alloy spring steel.
