ENGINES
–
An
Introduction
Almost
all
cars
currently
use
what
is
called
a
four-stroke
combustion
cycle
to
convert
gasoline
into
motion.
Modern
automotive
internal
combustion
engines
generate
a
huge
amount
of
heat.
It
has
been
stated
that
a
typical
average-sized
vehicle
can
generate
enough
heat
to
keep
a
5-room
house
comfortably
warm
during
zero
degree
weather.
The
Necessity
of
having
a
good
Engine
Cooling
System
An
Engine
Cooling
System
is
a
system
that
controls
the
engine
temperature,
is
known
as
a
cooling
system.
The
cooling
system
is
provided
in
the
IC
engine
for
the
following
reasons:
The
temperature
of
the
burning
gases
in
the
engine
cylinder
reaches
up
to
1500
to
2000°C,
which
is
above
the
melting
point
of
the
material
of
the
cylinder
body
and
head
of
the
engine.
(Platinum,
a
metal
which
has
one
of
the
highest
melting
points,
melts
at
1750
°C,
iron
at
1530°C
and
aluminium
at
657°C.)
Therefore,
if
the
heat
is
not
dissipated,
it
would
result
in
the
failure
of
the
cylinder
material.
Due
to
very
high
temperatures,
the
film
of
the
lubricating
oil
will
get
oxidized,
thus
producing
carbon
deposits
on
the
surface.
This
will
result
in
piston
seizure.
Due
to
overheating,
large
temperature
differences
may
lead
to
a
distortion
of
the
engine
components
due
to
the
thermal
stresses
set
up.
This
makes
it
necessary
for,
the
temperature
variation
to
be
kept
to
a
minimum.
Higher
temperatures
also
lower
the
volumetric
efficiency
of
the
engine.
The
two
main
requirements
of
an
efficient
cooling
system
are:
1.
It
must
be
capable
of
removing
only
about
30%
of
the
heat
generated
in
the
combustion
chamber.
Too
much
removal
of
heat
lowers
the
thermal
efficiency
of
the
engine.
2.
It
should
remove
heat
at
a
fast
rate
when
the
engine
is
hot.
During
the
starting
of
the
engine,
the
cooling
should
be
very
slow
so
that
the
different
working
parts
reach
their
operating
temperatures
in
a
short
time.
