TECHNICAL & CONSUMER INFORMATION
Emission
Control
System Information
Source of Emissions
The combustion process produces carbon monoxide, oxides of nitrogen, and
hydrocarbons.
Control of hydrocarbons
and oxides of nitrogen is very impor-
tant 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 utilizes lean carburetor
settings and other systems to reduce the
emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.
The U.S. and California
Clean
Air Acts
EPA and California
regulations
require all manufacturers
to furnish written
instructions
describing
the operation and maintenance
of emission control
systems.
The following instructions
and procedures
must be followed in order to keep
the emissions from your Honda engine within the emission standards.
Tampering and Altering

sions beyond the legal limit. Among those acts that constitute tampering are:
l

or

mechanism
