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 important because, under certain conditions, they I
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 US. 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
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.
Altering or defeating the governor linkage or speed-adjusting
mechanism to cause the engine to operate outside its design
parameters.
