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 systems to reduce the emissions of carbon monoxide, oxides
of nitrogen, and hydrocarbons.
The California Clean Air Act
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
Tampering with or altering the emission control system may increase emis-
sions beyond the legal limit. Among those acts that constitute tampering are:
Removal or alteration of any part of the intake, fuel, or exhaust systems.
0
Altering or defeating the governor linkage or speed-adjusting mechanism
to cause the engine to operate outside its design parameters.
