Tltis
valve
is

controlled

by
intake

manifold
vacuum
to

prevent
backfire

in
the

exhaust
system
at
the
initial

period
of

At
this

period
the
mixture
in

the

intake
manifold
becomes
too
rich
to

ignite
and
burn
in

the
combustion

chamber
and
burns

easily
in
the
ex

haust

system
with

injected
air
in
the

exhaust
manifold

The
anti

backfire
valve

provides
air

to
the
intake

manifold
to
make
the

air
fuel
mixture
leaner
and

prevents

backfire

If

the
valve
does
not
work

properly

unburned
ntixture
will
be

emitted

from

the
combustion
chambers
