GENERAL INFORMATION
EIVIISSIONCONTROLSVSTEMS
SOURCE OF EMISSIONS
The combustion process produces carbon monoxide and hydrocarbons. Controlling hydrocarbon emissions is very im-
portant because, under certain conditions, they react to form photochemical smog when subjected to sunlight. Carbon
monoxide does not react i n the same way, but
it
is toxic.
Honda Moler Co., Ltd. utilizes lean carburetor settings as well as other systems, to reduce carbon monoxide and hydrocar-
bons.
CRANKCASE EMISSION CONTROL SYSTEM
The engine is equipped with a closed crankcase system to prevent discharging crankcase emissions i n to the atmosphere.
Blow-by gas is returned to the combustion chamber through the air cleaner and carburetor.
