GENERAL INFORMATION
EXHAUST EMISSION CONTROL SYSTEM (SECONDARY AIR SUPPLY SYSTEM)
The exhaust emission control system is composed of
a lean fuel injection setting, and no adjustments should be made except
idle speed adjustment with the throttle stop screw. The exhaust emission control system is separate from the crankcase emis-
sion control system.
The exhaust emission control system also includes a secondary air supply system which introduces filtered air into the exhaust
gases in the exhaust port. Fresh air is drawn into the exhaust port by the function of the PAIR (Pulse Secondary Air Injection)
control valve.
This charge of fresh air promotes burning of the unburned exhaust gases and changes
a
considerable amount of hydrocar-
bons and carbon monoxide into relatively harmless carbon dioxide and water vapor.
The reed valve prevents reverse air flow through the system. The PAIR control valve is operated
by
the solenoid valve. The
solenoid valve is controlled
by
the PGM-FI unit, and the fresh air passage is
according the running condition

No adjustments to the secondary air supply system should be made, although periodic inspection of the components is
recommended.
AIR CLEANER HOUSING
California type:
The California type is equipped with two three-way warm-up catalytic converters,
a
three-way catalytic converter, and a
heated oxygen sensor.
The three-way catalytic converters are in the exhaust system. Through chemical reactions, they convert HC, CO, and
in
the engine’s exhaust t o carbon dioxide
dinitrogen
and water vapor.
No adjustment
to
these systems should be made although periodic inspection
of the components is recommended.
