TECHNICAL AND CONSUMER INFORMATION
Source of Emissions
Tampering and Altering The U.S. and Calif ornia Clean
Air Acts
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.
Tampering with or altering the
emission 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.
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.
Honda utilizes appropriate air/fuel
ratios and other emissions control
systems to reduce the emissions of
carbon monoxide, oxides of nitrogen,
and hydrocarbons.
