TECHNICAL INFORMATION
Emission Control System Information
Source of Emissions
The combustion process produces carbon monoxide, oxides of
nitrogen, and hydroca
rbons. Control of hydrocarbons and oxides of
nitrogen are 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.
Additionally, Honda fuel systems utilize components and control
tech
nologies to reduce evaporative em
issions.
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 k
eep 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 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.
• A
ltering or defeating the governor linkage or speed-adjusting
m
echanism to
cause the engine to operate outside its design
parameters.
