GENERAL INFORMATION
SYSTEMS OF EMISSION CONTROL
EMISSION SOURCE
The combustion process produces carbon monoxide and hydrocarbons. The control of hydrocarbons is very im-
portant. Under certain conditions, when exposed to sunlight, hydrocarbons react to produce haze and
photochemical smog. The carbon monoxide does not react in the same way. Still, is toxic.
Motor Honda da Amazonian Ltd. used mix settings of poor carburetor, as other procedures, in order to reduce
the emission of carbon monoxide and hydrocarbons.
CONTROL SYSTEM OF ISSUING THE ENGINE CRANKCASE
The engine introduced a system of crankcase closed to avoid the discharge of their gases into the atmosphere. The
gases emitted through the crankcase returning to the combustion chamber through the air filter and of the carburetor.
