TECHNICAL 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 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 utilizes appropriate air/fuel
ratios
and other emissions control
systems to reduce the emissions of
carbon monoxide, oxides of nitrogen,
and hydrocarbons.
The U.S., California Clean Air
Acts, and Environment Canada
EPA, California, and Canadian
regulations require all manufacturers
to furnish written instructions
describing the operation and
maintenance of emission control
systems.
The following instructions and
p
rocedures must be followed in order
to keep the emissions from your
Honda engine within the emission
standards.
Tampering and Altering
Tampering is a violation of Federal
and California law.
Tampering with or altering the
emis
sion control system may increase
emissions beyond the legal limit.
Among those acts that constitute
tampering are:
• Removal or alteration of any part
of
the intake, fuel, or exhaust
systems.
• Alterations that would cause the
engine to operate outside its design
parameters.
