INFORMATION ON THE NOISE
AND EXHAUST GAS EMISSION
CONTROL SYSTEM
ORIGIN OF THE EMISSIONS
The combustion process produces carbon
monoxide and hydrocarbons. The control of
hydrocarbons is very important, because under
certain conditions they react to exposure to
sunlight and produce photochemical smog.
Carbon monoxide does not react in the same
way, but it is toxic and poisonous. Derbi utilizes
"lean" carburetor settings to reduce the produc-
tion of carbon monoxide and hydrocarbons.
EXHAUST EMISSION CONTROL SYSTEM
The Exhaust Emission Control System requires
"lean" carburetor settings and no adjustments
should be made, except idle speed by means
of the appropriate screw.
The Exhaust Emission Control
System is separate from the
Cranckase Emission Control System.
CRANCKASE EMISSION CONTROL SYSTEM
The engine is equipped with a closed crancka-
se system, in order to avoid discharging the
cranckase emissions into the atmosphere. The
blow-by gas is returned to the combustion
chamber through the air cleaner and the throttle
valve.
EVAPORATIVE EMISSION CONTROL SYS-
TEM
In California vehicles are equipped with an eva-
porative emission control system consisting of
an activated carbon canister with the relevant
pipes. This system prevents the escape of fuel
vapours from the fuel tank.
