operates

properly

I
When

engine
speed
is
increased

discharge

pressure
of

causes

counterweight
to

move

2
For

some
time

after

counterweight

turns
counterclockwise
until
it

comes

into

Counterweight
gradually
moves

down

AIR

DESCRIPTION

The
Air

Injection
System
A
I
S

is

adopted
on
U
S
A

models

except
FU

models

and

injects
compressed
air

secondary
air

coming
from
the
air

pump
into

the
exhaust

port
of
the

cylinder
head
to
reduce

hydrocarbons

He
and

carbon

monoxide
CO
in

exhaust

gas
through
recombustion

There

are
two

types
of
Air

Injection

System

Fresh
outside
air
is
drawn

by
the
air

pump
through
the

air

pump
air

cleaner

Compressed
air
is

injected
into

the

exhaust

manifold

through
the

check
valve

The
A
B

valve

supplies
air
from
the

carburetor
air
cleaner
to
the

intake

manifold

so
as

to

prevent
after

fire

during
deceleration

The
amount

of

injected
air
is
con

trolled

by

To

is

needed

If
