For
the
engine
to
run
there
are
Eight
(8)
events
are
required
for
a
2
or
4
cycle
engine
to
operate.
First,
Air
is
drawn
into
the
cylinder
The
correct
amount
of
fuel
is
metered
into
the
air
The
air
and
fuel
are
mixed
The
air
fuel
mixture
is
compressed
The
spark
plug
fires
starting
combustion
Combustion
causes
a
rapid
rise
in
temperature.
The
increased
temperature
causes
pressure
to
increase
which
produces
a
force
on
the
piston.
The
connecting
rod
and
crankshaft
converts
the
linear
motion
to
rotary
motion.
The
burnt
gases
are
expelled
from
the
engine.
Do
not
confuse
these
events
with
the
four
strokes
(events)
of
a
four
cycle
engine.
