Description
Crankshaft,
Center
of
Power
Engine
crankshaft
The
explosion
that
happens
in
the
cylinder
causes
the
piston
to
be
thrust
downward
toward
the
inside
of
the
engine.
The
connecting
rod
connects
the
bottom
of
the
piston
to
a
certain
point
on
the
crankshaft,
transferring
the
energy
of
the
combustion
(the
explosion
in
the
cylinder)
from
an
up
and
down
movement
of
the
piston
and
connecting
rod
to
a
rotational
movement
in
the
crankshaft.
Every
time
combustion
occurs
in
a
cylinder,
the
crankshaft
is
rotated
a
little
more.
Each
piston
has
its
own
connecting
rod,
and
each
connecting
rod
is
attached
to
the
crankshaft
at
a
different
point.
Not
only
are
they
spaced
out
along
the
long
crankshaft,
but
they
are
attached
at
different
points
in
the
crankshaft’s
rotation,
as
well.
This means that a different part of the crankshaft is always being pushed along in the rotation. When this happens thousands of times a minute, you get a powerful engine capable of moving a car down the road.
Remember,
if
you
forget
to
add
oil
to
your
engine
or
change
your
oil
regularly,
you
run
a
high
risk
of
seriously
damaging
the
inside
of
your
engine.
All
of
those
parts
need
constant
lubrication!
Disadvantages Of Crankshaft
Crankshaft
Just
like
a
crank
on
a
jack
in
the
box
does,
the
crankshaft
changes
the
up
and
down
motion
of
the
piston
to
rotational
motion.

Design:
Based
on
the
chemical
composition
of
the
material
we
could
design
the
crankshaft
dimensions.
The
crankshaft
is
designed
according
to
two
positions
of
the
crank.
A.
When
the
crank
is
at
dead
centre
At
this
position
of
the
crank
the
max
pressure
on
the
piston
will
transmit
max
force
on
the
crankpin
in
the
plane
of
the
crank
causing
bending
at
the
shaft.
Since
the
bending
moment
on
the
shaft
is
maximum,
the
twisting
moment…show
