EMISSION CONTROL SYSTEM (USA ONLY)
Source of Emissions
The
combustion process produces carbon monoxide and hydrocarbons. Control of hydrocarbons
is very important because, under certain conditions, they react to form photochemical smog when
subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic.
Honda Motor Co., Ltd. utilizes lean carburetor settings to reduce carbon monoxide and hydrocar-
bons.
Exhaust Emission Control System
The
exhaust emission control system is composed of lean carburetor settings, 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 emission control system.
