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.
Additionally, Honda fuel systems utilize components and control
technologies to reduce evaporative emissions.
The U.S. and California Clean Air Acts, and Canadian Environmental
Protection Act
U.S. EPA, California and Canadian regulations require all manufacturers
to furnish written instruction describing the operation and maintenance
of emission control systems.
The following instructions and procedures must be followed in order to
keep the Honda engine emissions 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 intake, fuel, or exhaust system.
• Altering or defeating the governor linkage or speed-adjusting
mechanism to cause the engine to operate outside its design
parameters.
