The

accelerates
the
chemical
reaction
of
hydrocarbons

He
and
carbon
monoxide
O
in
the
exhaust
gas
and
changes
them
into
non

and

H20
This
chemical
reac
tiOD
process
requires
the
proper
a
mount
of
air
which
is
supplied
by
the
air

Refer

This

OPERATION
Exhaust
gas
emitted
from
the
en
gine
contains
some
harmful
substances
due
to
incomplete
combustion
in
the
combustion
chamber
The
air
injection
stem
i
designed
to
reduce
the
con
tent
of
such
substances
in
the
exhaust
gas
In
this
system
the
secondary
air
is
led
from
the
ch
ck
valve
and
injected
in
o
the
exhaust
manifold
With
this
injection
of
the
secondary
air
hydro
carbons
He
and
carbon
monoxide
CO
in
the
exhaust
gas
are
gradually
oxidized
with
oxygen
02
in
the
secondary
air
and
converted
into
nOD
harmful
carbon
dioxide
C02
and
water
HP
The
catalytic
converter
further
cleans
engine
exhaust
gas
Through
catalytic
action
it
changes
residual
hydrocarbons
and
carbon

contained
in
exhaust
gas
into
carbon
